    OPINION
    The appellant, John Allen Chapman, appeals from the April 2, 1994,
    Grundy County jury verdict finding him guilty of first degree murder, aggravated
    kidnapping, and aggravated sexual battery. The jury fixed the appellant’s
    sentence at life imprisonment for first degree murder and the trial court imposed
    maximum sentences of twelve years each for the remaining offenses and
    ordered all sentences to be served consecutively. On appeal, the appellant
    challenges:
    I. The sufficiency of the indictment charging aggravated
    kidnapping;
    II. The sufficiency of the evidence for all three convictions;
    III. The admission of DNA evidence;
    IV. Denial of the appellant's motion to suppress blood samples
    obtained during the investigation;
    V. Failure of the trial court to properly instruct the jury regarding
    identity;
    VI. The scope of cross-examination of State’s witnesses; and
    VII. Sentencing: length of sentences and imposition of consecutive
    sentences.
    After review, the judgment of the trial court is affirmed.
    BACKGROUND
    Guilt Phase
    On April 19, 1990, Michelle Blake, the victim in this case, was employed
    as a clerk at the Pit Stop South, a gas and convenience store in McMinnville.
    Mrs. Blake was twenty-six years old, married and the mother of a four-year-old
    daughter. On this date, she was scheduled to work the 3:00 p.m. to 11:00 p.m.
    2
    shift. At 5:15 p.m., Mrs. Blake's husband, William Blake, arrived at the Pit Stop
    South to pick up the couple's vehicle, a Ford Bobcat. He left the business,
    traveled to a video store, and then went home. As was customary, Blake was to
    return to the Pit Stop later that evening with his wife’s dinner.
    Around 8:30 p.m., Ed Martin stopped at the store to purchase gasoline.
    Martin pumped three dollars worth of gasoline and went inside the store to pay.
    As Martin was leaving the store, Mrs. Blake remarked, "I wish he'd go ahead and
    leave. I've already pumped his gas," referring to a man sitting outside the front
    of the store in an older model gray Chevrolet pick up truck which displayed
    Grundy County license plates.
    Fifteen minutes later, around 8:45 p.m., Sylvia Fults and her husband
    pulled into the drive-through window of the Pit Stop South to purchase cigarettes.
    Although she depressed the customer assistance button, no clerk appeared.
    She then noticed Mrs. Blake at the full service pump with a jug in her hand.
    Mrs. Blake re-entered the store to wait on Fults. While waiting on Fults, Mrs.
    Blake
    talked about this guy being there before getting gas and talking
    about him being so weird. She said he had been there earlier and
    got gas in his truck and he had left or started to leave, and came
    back and had her put gas in a can, and she said, 'Now he's back
    wanting it in a jug.'
    Mrs. Blake also told Fults that this man had asked her if she had wanted any
    help since she was at the store by herself. During this conversation, Fults
    noticed a man in the store who looked like he was trying to scare Mrs. Blake.
    When she was leaving the parking lot, she observed a "gray primer color" pick
    up truck with chrome parked in front of the store.
    Mary Jones lives across the street from the Pit Stop South. Around 8:55
    3
    p.m. on April 19, 1990, she heard what she thought to be a scream coming from
    the front of her house. After hearing an apparent second scream, she went to
    her front porch where she observed a truck on the Pit Stop’s parking lot. She
    stated that the truck was a "gray primer color" and had a Chevrolet logo across
    the back of the tailgate. She noticed a man and a woman in the truck. Ms.
    Jones related that “at one time it looked like she pulled away from him.” She
    assumed that, more than likely, it was simply a “domestic problem." The truck
    then pulled out of the parking lot and onto Highway 55. She commented that, as
    the truck left the parking lot, it was going very fast and that it made loud sounds.
    At 9:05 p.m., as planned, William Blake returned to the Pit Stop South
    with his wife's, dinner. When he arrived at the Pit Stop, he noticed two vehicles
    in the parking lot. Two customers approached him and inquired as to "what was
    going on" as there was no attendant on duty. Immediately, Blake began to
    search the premises for his wife. During this search, one of the customers
    discovered Mrs. Blake's eyeglasses in the parking lot. At this point, the police
    were called and the owner of the station, Mr. Stanton, arrived. After inspecting
    the premises, Mr. Stanton stated that no money had been taken from the cash
    register, although the key that functioned as the "on-off" switch was missing. A
    search then began in Warren County for Michelle Blake.
    Joe Roper informed law enforcement officials that, while traveling home
    on the evening of April 19, 1990, on route 108, a vehicle came up behind him at
    an excessive rate of speed and passed him on a double yellow line. He
    described the vehicle as being a gray Chevrolet pick up truck with large tires and
    Grundy County license plates. Roper also stated that there were two people in
    the truck. Dale Winton reported that, at 9:05 p.m., he was traveling on highway
    127 when a vehicle came up behind him "real fast" and swerved around him,
    4
    almost running him off the road.1 He described the vehicle as being a dark
    colored 1979 or 1980 Chevrolet pick up truck with "cherry bomb mufflers" and
    chrome on the side of the truck.
    Danny Wannamaker, whose residence is directly adjacent to the
    Philadelphia Cemetery in Grundy County, testified that, at around 9:20 p.m. on
    April 19, 1990, he took a shower and prepared for bed. Around 9:50 p.m., he
    heard a vehicle that sounded like it did not have a muffler. He looked out the
    window, but did not see anything. Again, he heard the vehicle stop for a few
    minutes, then "the motor was turned off, cranked back up and took off, again
    approaching the house." Herbert Lewis, who also lives behind the Philadelphia
    Cemetery, was at home alone on the evening of April 19, 1990. Shortly after
    9:30 p.m., he heard what appeared to be a female screaming for help, followed
    shortly thereafter, by a loud vehicle coming around the bend from behind the
    graveyard. He explained that he was not alarmed by the screams because he
    was “use (sic) to hearing people screaming, raising cane (sic) at the volleyball
    court."
    The next morning between 7:00 and 7:30 a.m., Sharon Shannon, the
    daughter of Herbert and Melba Lewis, dropped her six-month-old son off at her
    parents' home. As she was leaving, she spotted what at first appeared to her to
    be shoes, however, she soon realized it was a body. Because her eleven year
    old daughter was in the vehicle with her, she did not stop, but returned to her
    parents' home instead. After leaving her daughter with her parents, Shannon
    returned to the cemetery to verify the presence of the body and then contacted
    the authorities. The body was identified as that of Michelle Blake.
    1
    The proof at trial revealed that a motorist traveling between the Pit Stop South and the
    Philadelphia Cem etery would take Highway 55 to 108, 108 to 127, 127 to 56, 56 to the Grundy
    County line, then to the cemetery. The total distance of this trip is approximately 16.2 miles. At
    the poste d speed rate, th is dista nce take s an average of twe nty m inutes to travel.
    5
    An investigative team with the Tennessee Bureau of Investigation arrived
    at the scene. The victim was found fully clothed with her blouse partially
    unbuttoned. Her brassiere was missing. The victim's body was examined for the
    presence of hair, fibers, and fingerprints. Joe Minor, a member of the
    investigative team, testified that a whitish stain which appeared to be semen was
    discovered on the left breast of the victim’s body. The whitish stain extended
    from the victim’s breast to her stomach. Examination of the stain revealed that
    the substance did contain spermatozoa, and further testing indicated that the
    source of the semen was a Type B secretor.
    Dr. Charles Harlan, the chief medical examiner for the State of
    Tennessee, performed an autopsy upon the body of Michelle Blake on April 21,
    1990. His report identified a total of seven stab wounds, one to the left side of
    the neck, four to the left breast, and two to the mid-line of the back. He indicated
    that the wounds were caused by a single sided instrument, three to three and
    one-half inches in length. Three of the wounds caused damage to main organs
    which resulted in the victim's death, i.e., damage to the carotid artery, damage to
    the heart, and damage to the right lung. He opined that death occurred within
    three to ten minutes of the injuries. The medical examiner further explained that
    a sharp line of demarcation existed on the victim's neck, indicative of ligature
    strangulation. He noted there were no defensive wounds and no evidence of
    forcible vaginal intercourse. He also determined that the victim's blood was
    type O.
    Despite descriptions of the perpetrator, his truck, and available scientific
    evidence, the case remained unsolved for over two years. In July, 1992, Special
    Agent Larry Davis with the Tennessee Bureau of Investigation, was called to
    6
    assist Grundy County officials in the investigation of the June 7 murder of Vicky
    Sue Metzger, whose body was discovered at the I-24 Eastbound Rest Area near
    Monteagle. On July 13, Davis interviewed the appellant who was the attendant
    on duty at the rest area on the date of the murder. The attendant at the
    westbound rest area was also interviewed. Neither man was placed under
    arrest, although both men were asked to submit blood samples for DNA
    comparison analysis on semen found on the victim. On November 5, 1992,
    Davis was requested to assist in the investigation of an assault on another victim
    at the I-24 Eastbound Rest Area. On this occasion, the appellant was identified
    as the assailant and was in custody at the Monteagle police station when
    interviewed by Agent Davis. The appellant "stated that he had assaulted the
    victim because he had been drinking and smoking marijuana." Again, the
    appellant submitted to blood testing. 2
    From these tests, it was determined that the appellant has Type B blood.
    Review of the case file at this point led authorities to the belief that the appellant
    may have been involved in the 1990 death of Michelle Blake. DNA comparison
    analysis was then requested on the appellant's blood sample and the semen
    sample recovered from Mrs. Blake's body. The results from the tests revealed
    that the DNA binding pattern on each sample matched. Additional forensic tests
    established that fibers found on the victim's clothing were consistent with the
    fibers found in the carpet of the appellant’s Chevrolet pick up truck. The proof at
    trial established that, in April, 1990, the appellant lived in Grundy County and
    was employed by a nursery in Warren County. On occasion, after regular
    working hours at the nursery, he would work for his supervisor, Floyd Hardcastle,
    who lived in Warren County. When working for Mr. Hardcastle, his commute to
    and from home would take him by the Pit Stop South. The appellant admitted
    2
    Evidence of the crim es against V ick y Metzger an d Pam ela Sue Back, the second victim
    at the I-24 eastbound Rest Area, was developed during pre-trial suppression hearings.
    7
    that he had, on occasion, purchased gas at the Pit Stop South. However, when
    showed the photograph of Michelle Blake at trial, he stated that he did not
    recognize her. On cross-examination, the State introduced a payroll check from
    Hardcastle to the appellant, dated March 3, 1990, which was cashed at the Pit
    Stop South, bearing the initials “M.B.” The initials were identified as being those
    of Michelle Blake. The appellant also admitted that, in April, 1990, he owned a
    1977 gray Chevrolet short-bed pickup truck which displayed Grundy County
    license plates. He stated that he sold the truck in the spring of 1991.
    Additionally, the proof established that, in April of 1990, the appellant’s truck had
    other matching characteristics to that of the truck driven by the abductor of
    Michelle Blake.
    Based upon the evidence introduced, the jury convicted the appellant of
    first degree murder, aggravated kidnapping, and aggravated sexual battery.
    Following the testimony of various defense witnesses and the proof
    introduced at the guilt phase, the jury fixed the appellant’s sentence for first
    degree murder at life imprisonment.
    Sentencing Phase: Aggravated Kidnapping and Aggravated Sexual Battery
    The hearing to determine the appropriate sentences for the appellant's
    remaining convictions was held on May 12, 1994. The presentence report
    revealed that, at the time the report was prepared, the appellant was a twenty-six
    year old Caucasian male, married, and the father of a three year old son. He
    has a tenth grade education. After dropping out of school, he joined the
    Tennessee National Guard. He received an honorable discharge in 1992
    attaining the rank of E-4. He admits to being an alcoholic and to occasional
    marijuana use. Since 1987, the appellant has worked for various employers in
    8
    the nursery business and, briefly, as a rest area attendant. Regarding the
    appellant's prior record, the report indicated that the appellant, on the date of the
    sentencing hearing in this case, had one count of first degree murder, one count
    of aggravated rape and two counts of aggravated robbery pending in the Grundy
    County Circuit Court. Additionally, the appellant has three prior convictions for
    driving while intoxicated, one conviction for possession of marijuana, and one
    conviction for driving on a revoked license. He was arrested for possession of a
    weapon for purposes of going armed, however, this charge was dismissed upon
    payment of costs and confiscation of the firearm.
    Larry Davis, a special agent with the TBI, testified regarding his
    investigation of the murder of Vicky Sue Metzger and the assault of Pamela Sue
    Back. He explained that, through his investigation of these two cases, the TBI
    was able to target the appellant as a suspect in the present case. He also
    recounted the appellant's confession to the assault on Pamela Sue Back.
    The trial court found three non-statutory mitigating factors and five
    statutory enhancement factors applicable. In doing so, the court imposed the
    maximum sentence of twelve years for each conviction within the range.
    Moreover, based upon the allegations of the pending indictments, the court
    concluded that the appellant was a dangerous offender and ordered that all
    sentences be served consecutively.
    I. Sufficiency of the Indictment
    The appellant first contends that the indictment for aggravated kidnapping
    is void because it fails to set forth the essential elements of the offense.
    Specifically, he argues that the indictment fails to allege the elements of false
    9
    imprisonment, which is an essential element of aggravated kidnapping. Count
    two of the indictment, which charged the offense of aggravated kidnapping,
    alleged in pertinent part as follows:
    JOHN ALLEN CHAPMAN . . . did unlawfully, (intentionally), . . .
    remove and confine one Michelle Darlene Blake with the intent to
    inflict serious bodily injury upon the person of the said Michelle
    Darlene Blake, in violation of . . . Tenn. Code Ann. § 39-13-301. . .
    .3
    (Emphasis added)
    The appellant acknowledges that the charging instrument includes the
    statutory language “did unlawfully . . . remove and confine” one Michelle Darlene
    Blake. He argues, however, that the failure of the indictment to include the
    remaining statutory language “so as to interfere substantially with the other’s
    liberty” renders the indictment void.
    An indictment should state the facts constituting the offense in ordinary
    and concise language in such a manner as to enable a person of common
    understanding to know what is intended, and with that degree of certainty which
    will enable the court, on conviction, to pronounce the proper judgment. Tenn.
    Code Ann. § 40-13-202 (1990); State v. Marshall, 
    870 S.W.2d 532
    , 537 (Tenn.
    Crim. App. 1993). This court recently held that “[i]f an offense is alleged in such
    a way that the defendant cannot fail to be apprised of the elements of the
    offense, the indictment is sufficient, notwithstanding the fact that an element may
    not be specifically alleged.” See State v. John Haws Burrell, No. 03C01-9404-
    CR-00157, (Tenn. Crim. App. at Knoxville, Feb. 11, 1997) (Rule 11 application
    filed, April 10, 1997).
    The indictment in this case alleges that the appellant removed and
    3
    Tenn. Code Ann. § 39-13-304(a) (1989) defines aggravated kidnapping as "false
    imprisonment com mitted . . . (3) with the intent to inflict serious bodily injury. . . ." False
    imprisonm ent is the know ing rem oval or confinem ent of ano ther u nlawfully so as to interfe re with
    the other's liberty. Ten n. Code A nn. § 39-13-30 2 (1989).
    10
    confined Michelle Darlene Blake with the intent to inflict serious bodily injury. We
    find the language of the indictment provides constitutionally sufficient notice of
    the offense charged as well as suitable protection against double jeopardy. This
    issue is without merit.
    II. Sufficiency of the Evidence
    Next, the appellant challenges the sufficiency of the convicting evidence
    as to each count of the indictment. Within this challenge, he alleges (1) that the
    evidence fails to prove, in regards to the aggravated kidnapping conviction, that
    "any removal or confinement substantially interfered with the victim's liberty;" (2)
    that, concerning the aggravated sexual battery conviction, there was no proof of
    unlawful sexual contact with the victim; and (3) that the State failed to establish,
    by either lay or expert testimony, that the appellant was, indeed, the perpetrator
    of the offenses committed against Ms. Blake.4
    When a challenge is made on appeal to the sufficiency of the convicting
    evidence, this court must adhere to certain well-established principles. First, a
    jury conviction removes the presumption of innocence with which a defendant is
    initially cloaked and replaces it with one of guilt, so that on appeal a convicted
    defendant has the burden of demonstrating that the evidence is insufficient.
    State v. Tuggle, 
    639 S.W.2d 913
    , 914 (Tenn. 1982). Next, the State is entitled to
    the strongest legitimate view of the evidence and all reasonable or legitimate
    inferences which may be drawn therefrom. State v. Harris, 
    839 S.W.2d 54
    , 75
    (Tenn. 1992). Moreover, this court may not reweigh or reevaluate the evidence.
    State v. Cabbage, 
    571 S.W.2d 832
    , 835 (Tenn. 1978). Viewing the evidence
    under these criteria, it is this court's responsibility to affirm the conviction if the
    4
    The appellant does not challenge the sufficiency of the convicting evidence as to the
    offense of first d egree m urder other than to th e issue of the perpetrator's identity.
    11
    proof was sufficient for any rational trier of fact to have found the essential
    elements of the offense beyond a reasonable doubt. Jackson v. Virginia, 
    443 U.S. 307
    , 317, 
    99 S. Ct. 2781
    , 2789 (1979); State v. Cazes, 
    875 S.W.2d 253
    , 259
    (Tenn. 1994); Tenn. R. App. P. 13(e). This rule is applicable to findings of guilt
    predicated upon direct evidence, circumstantial evidence, or a combination of
    both direct and circumstantial evidence. State v. Matthews, 
    805 S.W.2d 776
    ,
    779 (Tenn. Crim. App. 1990).
    A. Aggravated Kidnapping
    The jury found the appellant guilty of aggravated kidnapping pursuant to
    Tenn. Code Ann. § 39-13-304(a). In order to obtain a conviction under this
    statute, the State must prove that the defendant committed the act of false
    imprisonment, as defined in §39-13-302, supra note 5, with the intent to inflict
    serious bodily injury. . . ." Tenn. Code Ann. § 39-13-304. The proof establishes
    that Mrs. Blake disappeared from the Pit Stop South during her scheduled shift,
    leaving behind her eyeglasses, which were later found in the parking lot. Her
    disappearance coincided with the appearance of the appellant at the
    convenience store. Mrs. Blake did not know the appellant. Various witnesses
    thought they heard the victim's screams. The following morning, the victim was
    found brutally murdered. We find nothing from these facts to suggest that the
    departure of the victim from her place of employment was occasioned by any
    thing other than removal and confinement by force, ultimately resulting in her
    death. This issue is without merit.5
    B. Aggravated Sexual Battery
    Next, the appellant challenges his conviction for the aggravated sexual
    battery committed against Michelle Blake. Although he concedes that the proof
    5
    W ithin this issue, the appellant, again, contends that the indictment fails to allege that
    "any removal or confinement substantially interfered with the victim's liberty." This contention has
    prev iously been add ressed in Section I, and, w as fo und to be withou t m erit.
    12
    establishes serious bodily injury, i.e., multiple stab wounds, he contends that
    there is "no proof of any sexual contact with Mrs. Blake's body either before or
    after her death. The entire proof on this issue consisted of the testimony that. . .
    a semen stain was recovered from the left portion off her body extending from
    her left breast to her abdominal area." He argues that the "record discloses no
    evidence whatsoever that the victim's intimate parts were touched as part and
    parcel of a sexual act."
    In order to sustain a conviction for aggravated sexual battery, this court
    must find that the proof establishes that the appellant made unlawful sexual
    contact with the victim and caused bodily injury to the victim. Tenn. Code Ann. §
    39-13-504 (a)(2) (1989). "'Sexual contact' includes the intentional touching of
    the victim's, the defendant's, or any other person's intimate parts, or the
    intentional touching of the clothing covering the immediate area of the victim's,
    defendant's, or any other person's intimate parts, if that intentional touching can
    be reasonably construed as being for the purpose of sexual arousal or
    gratification." Tenn. Code Ann. § 39-13-501(6) (1989) (emphasis added).
    "'Intimate parts' includes the . . . breast of a human being." Tenn. Code Ann. §
    39-13-501(2). Again, as the appellant concedes, the proof showed semen stains
    on Michelle Blake's left breast and abdomen. DNA evidence, identity testimony,
    and other circumstantial evidence linked the appellant to the crimes committed
    against Mrs. Blake. Clearly, from the proof introduced, the jury could have
    rationally inferred that it was the appellant who deposited the semen on the
    victim's breast. This fact is sufficient to establish sexual contact. Our statute
    does not require that “intentional touching” of the victim’s intimate part result from
    direct contact with the defendant’s hand or any other part of the defendant’s
    body. This issue is without merit.
    C. Identity of the Perpetrator
    13
    The appellant's main contention regarding his challenge to the sufficiency
    of the evidence is that the proof fails to establish that he is the perpetrator of the
    offenses. Specifically, the appellant questions the reliability of eyewitness
    testimony identifying him "as the individual at the Pit Stop South at or near 8:50
    p.m. or thereafter on April 19," and, he attacks the accuracy of the scientific
    evidence due to deficient collection of evidence and inappropriate scientific
    procedures.6 The State responds that both the direct and circumstantial proof
    establish the appellant as the offender in this case.
    Ed Martin and Sylvia Fults provided identification testimony at trial.7
    Moreover, the proof at trial revealed numerous matching characteristics between
    the appellant’s truck and the truck driven by the abductor of Michelle Blake. Both
    trucks were described as older model trucks, both short-wheeled base, both gray
    in color, both displayed Grundy County license plates, both had loud mufflers,
    both had chrome on the side, and both had the name “Chevrolet” on the tailgate.
    Fibers later obtained from the appellant's truck were consistent with those
    obtained from Michelle Blake's clothing. Other proof revealed that testing of the
    semen found on Michelle Blake's body indicated that the perpetrator has Type B
    blood. The appellant has Type B blood. Moreover, the DNA binding patterns
    obtained from the two samples matched.8
    The State must prove beyond a reasonable doubt that the accused is the
    person who committed the offense. See White v. State, 
    533 S.W.2d 735
    , 744

    determination of identity is a question of fact for the jury after a consideration of
    all competent evidence. See Biggers v. State,

    (Tenn. Crim. App. 1982); State v. Hodge, No. 6 (Tenn. Crim. App. at
    Jackson, June 30, 1987). Likewise, the determination of whether all reasonable
    theories are excluded by the circumstantial evidence presented is primarily a
    question of fact for the jury. Pruitt v. State, 
    460 S.W.2d 385
    (Tenn. Crim. App.

    Before an accused may be convicted upon circumstantial evidence alone, the
    facts must be “so clearly interwoven and connected that the finger of guilt is
    pointed unerringly at the defendant and the defendant alone.” State v. Howell,
    
    868 S.W.2d 238
    , 253-254 (Tenn.), cert. denied, - - U.S. - -, 
    114 S. Ct. 1339
    (1993).
    We conclude that the proof in the record points the finger of guilt
    unerringly at the appellant and the appellant alone, and that the proof was
    sufficient for a jury to have found the essential elements of the offenses beyond
    a reasonable doubt.
    III. DNA Opinion Evidence
    Prior to trial, the appellant filed a motion in limine seeking to exclude the
    results of a DNA profiling analysis performed by Cellmark Diagnostics, a private
    Maryland laboratory contracted by the Tennessee Bureau of Investigation in the
    present case. These results revealed that the appellant's DNA matched DNA
    15
    samples (semen) recovered from the victim. At the conclusion of a lengthy
    hearing on the appellant's motion, the trial court, after considering the testimony
    of Dr. Lisa Forman, a Cellmark representative, ruled that the expert testimony
    concerning the DNA analysis was admissible.
    At trial, Dr. Forman and Julie Cooper, a senior molecular biologist with
    Cellmark, testified on behalf of the State regarding Cellmark's testing procedures
    and the results attained in the present case. To rebut this testimony, the
    defense presented the testimony of Dr. Marvin Shapiro, a professor at Emory
    University, and Dr. Ronald T. Acton, a professor at the University of Alabama.
    Dr. Shapiro opined that Cellmark used an insufficient database by failing to
    employ an Appalachian subgroup database, in determining their frequency
    calculation, and, as such, their results cannot be deemed accurate or reliable.
    Dr. Acton commented on the ongoing concerns in the scientific community with
    the use of ethidium bromide at the beginning of the analysis procedure.9 He
    further noted that Cellmark's combination of probes furnished results which were
    just an estimate at best and that Cellmark's method of combining probes has not
    been scientifically validated.
    On appeal, the appellant contends that the trial court failed to properly
    apply Tenn.R.Evid. 702, 703, and 403 in reaching its decision to allow the State
    to introduce DNA opinion testimony. Specifically, he asserts that the testimony
    introduced by representatives of Cellmark Diagnostic, the testing laboratory, is
    inadmissible because Cellmark's testing procedure indicates a "lack of
    trustworthiness." In this regard, the appellant contests:
    (1) Cellmark's use of ethidium bromide in the agarose gel before
    electrophoresis;
    9
    Ethidium bromide is a florescent dye that binds to DNA, allowing it to be visualized.
    16
    (2) Cellmark's selection and use of a Caucasian database from
    Delaware and failure to use a database exclusively from
    Appalachia; and
    (3) Cellmark's statistical analysis of the population frequencies.
    The appellant challenges specific techniques employed by Cellmark in the
    DNA analysis performed in this case. Due to the complex nature of the subject
    matter, an understanding of the structure of the DNA molecule and the precise
    procedures utilized is helpful to our review.
    A. Scientific Background
    I. DNA Structure
    The DNA molecule is a double helix, shaped like a twisted ladder.
    Phosphate and deoxyribose sugar form the rails of the ladder. Four chemical
    bases -- Adenine (A), Cytosine (C), Guanine (G), and Thymine (T) - lie next to
    each other on the sugar links along the sides of the ladder. Each A always
    bonds with a T on the other side of the ladder, and each C always bonds with a
    G on the other side of the ladder, so that the possible base pairs on the ladder
    are A-T, T-A, C-G, and G-C. The base pairs, e.g., A-T, C-G, are connected by a
    hydrogen bond, such that the bonds form the rungs of the ladder. There are
    approximately three billion base pairs in one DNA molecule. The sequence of
    the base pairs is the same in every cell of a person's body.
    Of the three billion base pairs, ninety-nine and nine-tenths percent are
    identical among all human beings. It is this identity that makes humans look like
    humans. Thus, only the remaining one-tenth of one percent of a person's base
    pairs vary from person to person.10 These sequences of variation from person to
    person are known as polymorphisms. Polymorphisms are the key to DNA
    10
    W e note that identical twins have all three billion pairs the same.
    17
    identification because they create the individual characteristics of each human
    being and they are detectable in laboratory testing.
    ii. Generating DNA Profiles
    Testing for DNA identification involves disassembling the ladder (DNA
    molecule) in one of several ways. Cellmark Diagnostics, the testing laboratory in
    this case, employs the Restriction Fragment Length Polymorphism (RFLP)
    method of analysis. The RFLP method determines if there is a "match." A
    "match" does not mean that the suspect is with certainty the source of the
    genetic material found at the crime scene or on the victim, but only that the
    suspect cannot be eliminated as a potential source. RFLP analysis involves
    extracting and isolating small portions of the DNA molecule to examine sites on
    the DNA that exhibit highly variable characteristics.11
    The preliminary procedure is to extract a DNA molecule from a sample of
    certain tissue or bodily fluid by using chemical enzymes and then to purify that
    sample. The DNA molecule is "cut" into smaller fragments with chemical
    scissors called restriction enzymes. These enzymes recognize certain base
    pairs and sever the DNA molecule at specifically targeted base pair sites to
    produce RFLPs. The cut fragments of DNA molecules (RFLPs) are next placed
    in an agarose gel and ethidium bromide is incorporated into the gel.12 The gel is
    then electrically charged to sort the fragments by length. This process is known
    as electrophoresis. The electric current causes the fragments to migrate through
    the gel. The distance traveled depends upon the length of the fragments; the
    11
    The following procedure explained herein summ arizes the RFLP procedure utilized by
    Cellmark D iagnostic in the present case. W e acknowledge, however, that other variations of the
    RFLP m ethod of DNA analysis exist and are employed successfully by other laboratories.
    12
    Questions have arisen concerning the use of ethidium brom ide at the beginning of the
    process. Using ethidium brom ide prior to electrophoresis has been shown to alter the mobility of
    fragm ents at high DN A co nce ntration s, thus de creasing the reliability of fragm ent size
    measurem ents.
    18
    shorter fragments, because they are lighter, will travel further in the gel. Once
    migration has ceased, the fragments of known base pair lengths are placed in
    separate lanes to allow the measurement of RFLPs in units of base pairs. A
    nylon membrane is placed over the gel, permanently transferring the RFLPs to
    this more functional surface.13 A denaturization process occurs during this step,
    severing each double-stranded DNA fragment into two single strands. This
    facilitates detection of specific RFLPs and Variable Number Tandem Repeats
    (VNTRs), i.e., the number of repeat core sequences of base pairs which
    determine the length of each RFLP.
    RFLPs that are defined by specific sequences are detected by
    hybridization with a genetic probe, a single stranded segment of DNA tagged
    with a radioactive reporter molecule designed to detect a complementary single
    strand base sequence.14 The membrane is placed in a bath that contains the
    probe, and the probe hybridizes to the target denatured RFLP.
    Next, the nylon membrane is placed in contact with a piece of x-ray film
    where the radioactive probes expose the film at their respective locations.15
    Black bands appear where the radioactive probes have bonded to the RFLPs,
    producing a DNA "print," or autorad. The position of each band indicates the
    location of a polymorphic segment on the blot. Location, in turn, indicates the
    length of the DNA fragment that contains the polymorphic DNA segment.16 The
    particular region on the DNA where a specific VNTR occurs is called a locus. A
    locus is considered polymorphic when the number of VNTRs varies from
    individual to individual. Each locus consists of variant forms of genes known as
    13
    Th is proces s is k now n as "Sou thern Blotting."
    14
    The probes utilized in this case were MS1, MS31, MS43, G3.
    15
    This pro cess is re ferred to as autoradiography.
    16
    It is the length of the DNA fragments that individualizes each living thing, thus, the
    position of the bands on a DNA print can differentiate individuals.
    19
    alleles. Two allele forms occupy each locus, one on a chromosome inherited
    from the mother, and one on a chromosome inherited from the father. When the
    same form of allele occupies both loci on the chromosomes the individual is
    homozygous for that allele, and when different alleles occupy the loci, the
    individual is heterozygous for both alleles.17 Typically, this process is repeated
    with four or five different probes. Several probes are necessary because,
    although the degree of individualization for the two alleles that occur on one
    locus is not high, it is extremely rare for two people to have eight or ten matching
    alleles across four or five different loci.
    The last step in the RFLP process is to determine if a match exists in the
    two lanes of the autorad between the DNA sample from the suspect and the
    forensic sample taken from the crime scene or the victim.18 If it matches, the
    analyst must determine the likelihood that someone other than the suspect might
    have the same DNA pattern. This calculation of the probability of a random
    match generates a ratio to accompany a match, the purpose of which is to
    express the statistical likelihood that an unrelated person chosen at random from
    a particular population could have the same DNA profile as the suspect.
    iii. Frequency Calculations
    The initial process in generating this ratio involves the creation of an
    autorad database. In the present case, Cellmark's database was comprised of
    DNA autorads from Caucasian individuals who donated blood at a Delaware
    blood bank, along with an African-American database, and a Hispanic database.
    Racially similar databases are used to create a greater likelihood of a DNA
    profile match, which safeguards against understating the probability of a random
    17
    The alleles which comprise the loci consist of multiple pairs of the nucleotide bases A, T,
    G, a nd C , supra, wh ich bond according to th e base pair rule . In order to generate a profile that is
    unique, C ellm ark studies four highly variab le sites referred to as polym orph ic loci.

    20
    match.
    Once a database is constructed, autorad band frequencies are calculated
    by comparing the known bands with the database bands to determine how
    frequently bands match. Scientists use either fixed or floating bin analysis to
    calculate match frequencies. Binning helps to account for variables in recording
    autorads, and provides confidence limits on frequency estimates. Cellmark
    employs a floating bin analysis. Floating bin analysis focuses on the autorads
    obtained from the evidence sample, around which individual bins are
    constructed. Typically, floating bins are constructed with a resolution tolerance
    of a certain number of standard deviations centered around the evidence band.
    Database bands which fall within the bin created from the evidence band are
    then assigned to the evidence band's floating bin to calculate band frequencies.
    Binning typically results in higher probable match frequencies. The higher match
    frequencies weigh in a suspect's favor because the probability calculations will
    yield a greater chance of a random match.19
    After individual band frequencies are calculated, the likelihood that the
    complete autorad would be duplicated in a randomly selected individual is
    calculated using the product rule. The product rule is simply the mathematical
    formula used to determine the probability that two independent events would
    occur simultaneously, calculated by multiplying the probability of each event.
    Two product rule calculations are required to determine the likelihood of a
    random profile match. First, the frequency of a match at each locus is
    19
    In the present case, a combination of two bands was necessary in order to calculate the
    frequency. Cooper used the analysis specific to probes MS1 and MS31 because they could be
    identified in the evidence as well as in the blood. However, the remaining three bands were either
    MS43 or G3. So, a combined analysis was completed on the final three bands. Cooper testified
    that the com bination of data in determining a frequenc y statistic results in a m ore cons ervative
    num ber.
    21
    calculated.20 After the frequency for each locus is calculated, the frequency of
    the complete genotype (genetic makeup of an organism) is calculated by
    multiplying together the four loci frequencies.
    Product rule probabilities are only accurate estimates if the events
    underlying the calculations are truly independent and random. Independence
    means the probability of finding one allele is not affected by having found any
    other allele. For each locus, event independence occurs when there is no
    correlation between the allele inherited from an individual's mother and the allele
    inherited from that individual's father. When no correlation between the two
    parental alleles exists the population sample is considered in Hardy-Weinberg
    equilibrium.21 Several critics have noted that there is a problem in that the
    product rule method is based on incorrect assumptions that (1) members of the
    racial groups represented by the broad data bases, Caucasians, Black, Hispanic,
    etc., mate within their groups at random, without regard to religion, ethnicity, and
    geography, and (2) the DNA fragments, identified by DNA processing behave
    independently and they are independent in a statistical sense. Contrary to the
    assumption of random mating, ethnic subgroups within each random data base,
    tend to mate within a specific subgroup, e.g., the Appalachian subgroup, Jewish
    subgroup. Such endogamous mating tends to maintain genetic differences
    between subgroups, as a result, the subgroups may have substantial differences
    in the frequency of a given DNA fragment, or VNTR allele, identified in the
    20
    Be cause the bands generated at each locus depend on whethe r the individual is
    homozygous or heterozygous for those particular alleles, the formula varies depending on the
    allele form. The frequency for a homozygous allele is computed using the formula p(al)2; the
    frequency for a heterozygous allele is computed using 2(p(al1)p(al2)); where p denotes
    probability, and al represents each allele.
    21
    Hardy-W einberg prin ciples derive from an algebraic equatio n that describes th e genetic
    equilibrium within a population. The principle states that gene frequencies will remain constant
    from generation to generation within a population unless outside forces act to change it, provided
    mating remains random.
    22
    processing step of DNA analysis.22 A given VNTR allele may be relatively
    common in some subgroups but not in the broader database. Thus, some critics
    argue that the current method, using the Hardy-Weinberg equation and the
    product rule, will be reliable only if there is extensive study of VNTR allele
    frequencies in a wide variety of ethnic subgroups. However, the National
    Research Academy remarks that "[t]he goal is not to ensure that the ethnic
    background of every particular defendant is represented, but rather to define the
    likely range of allele frequency variation." NATIONAL RESEARCH COUNSEL , DNA
    TECHNOLOGY IN FORENSIC SCIENCE 82-85 (1992). Moreover, to overcome the
    problem of allele frequency within a genetic subgroup, the National Research
    Academy recommends employing the ceiling principal in determining frequency
    statistics. 
    Id. When requested,
    as in the present case, Cellmark also employs what is
    known as the "ceiling principle" to calculate statistical frequencies. The ceiling
    method also uses the product rule. This method obtains the most conservative
    bin for every band and then multiplies it together, generally resulting in a more
    conservative number. Using the aforementioned procedures, Cellmark
    determined that the frequency reported, in the present case, as far as the
    Caucasian race, was one in nineteen thousand.
    B. Standard of Admissibility
    In State v. Harris, 
    866 S.W.2d 583
    , 586 (Tenn. Crim. App. 1992), this
    court addressed the proper standard for determining the admissibility of scientific
    evidence and testimony. 23 The court acknowledged the Frye test, see Frye v.
    22
    This hypothesis is the basis of the appellant's challenge of Cellmark's results. He
    argues that, sin ce an Appalachian subgroup was not em ployed by C ellm ark, the ratio produced in
    the instant case cannot be accurate.
    23
    The appellant correctly states that Tenn. Code Ann. § 24-7-117 (1991) (admissibility of
    the res ults of D NA analysis in civil or crim inal trials) is inconsequentia l to th e present c ase as it
    only applies "to persons comm itting or attempting to comm it one of the offenses set out in § 40-
    35-3 21 o n or a fter July 1, 199 1." See Com piler's Notes, Tenn. Code Ann. § 24-7-117. The
    23
    United States, 
    293 F. 1013
    (D.C. Cir. 1923), which requires that the scientific
    analysis from which the ultimate deduction is made must be "sufficiently
    established to have gained general acceptance in the particular field in which it
    belongs." 
    Id. at 1014.
    Additionally, the court recognized the Tennessee Rules of
    Evidence, which provide:
    If scientific, technical, or other specialized knowledge will
    substantially assist the trier of fact to understand the evidence or to
    determine a fact in issue, a witness qualified as an expert by
    knowledge, skill, experience, training, or education may testify in
    the form of an opinion or otherwise.
    Tenn.R.Evid. 702. However, the rule adds that the court "shall disallow
    testimony in the form of an opinion or inference if the underlying facts or data
    lack trustworthiness." Tenn.R.Evid. 703 (emphasis added).
    The court in Harris chose not to accredit one standard over the other, as
    the evidence at issue satisfied both requirements. See 
    Harris, 866 S.W.2d at 587
    . Subsequently, however, the United States Supreme Court in Daubert v.
    Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    , 587, 
    113 S. Ct. 2786
    , 2793
    (1993), held that the Frye test, "absent from and incompatible with the Federal
    Rules of Evidence, should not be applied in federal trials." Daubert does not by
    its terms, however, apply to state court proceedings. Although Tenn.R.Evid. 703
    and Fed.R.Evid. 703 are identical, Tenn.R.Evid. adds the sentence: "The court
    shall disallow testimony in the form of an opinion or an inference if the underlying
    facts or data indicate a lack of trustworthiness." In this respect, the Tennessee
    rule expresses a greater concern with the bases of expert testimony than its
    federal counterpart. Omni Aviation v. Perry, 
    807 S.W.2d 276
    , 281 (Tenn. App.
    1990). Moreover, our supreme court has held that the requisite foundations
    which must be established prior to the admission of scientific evidence are that
    (1) the facts underlying the testimony must be reasonably relied upon by experts
    offenses in the present case occurred on or about April 19, 1990.
    24
    in the particular field and (2) the facts must be trustworthy. State v. Ballard, 
    855 S.W.2d 557
    , 562 (Tenn. 1993); see also Advisory Commission Comments,
    Tenn.R.Evid. 703. We conclude that the "general acceptance standard"
    espoused in Frye is necessarily implicit within the requirements of Tenn.R.Evid.
    703. See Advisory Commission Comments, Tenn.R.Evid. 702 (Tennessee law
    is consistent with the Frye test). Accordingly, before expert testimony regarding
    DNA analysis may be admitted in Tennessee, the proposed testimony and
    evidence must meet the standards promulgated by Tenn.R.Evid. 702 and 703.
    C. Application of Standard
    The trial court concluded that Cellmark's techniques in generating a DNA
    profile and formulating a statistical frequency were based on accepted scientific
    practice and are trustworthy.24 See, e.g., 
    Harris, 866 S.W.2d at 586
    (approving
    RFLP analysis); accord State v. Begley, No. 01C01-9411-CR-00381 (Tenn.
    Crim. App. at Nashville, Jan. 11, 1996), perm. to appeal granted, (Tenn. July 1,
    1996). Generally, the qualifications, admissibility, relevancy, and competency of
    expert testimony are matters which largely rest within the sound discretion of the
    trial court, unless such discretion is arbitrarily imposed. 
    Ballard, 855 S.W.2d at 562
    ; see also State v. Schimpf, 
    782 S.W.2d 186
    , 191 (Tenn. Crim. App. 1989).
    Without evidence that Cellmark's standards were somehow deficient, we cannot
    conclude that the trial court abused its discretion or that the laboratory's
    conclusion was unreliable.
    Once evidence is properly admitted, disputes over its reliability go to its
    weight. Here, much of the appellant's attack focused on Cellmark's
    implementation of DNA frequency analysis and specifics of Cellmark's
    procedures, including the size of Cellmark's database, whether the sampling of a
    24
    The procedu res and protoc ols em ployed by Cellmark in the presen t case are
    substantially in compliance with the recomm ended procedures of the Technical W orking Group on
    DN A Ana lysis Me thods (TW GD AM ).
    25
    Delaware blood bank was truly random, and alleged problems with the
    electrophoresis process. This attack was presented to the jury through the
    testimony of Drs. Shapiro and Acton. Differences in the opinions of experts are
    inevitable in the application of science to the law. In our opinion, these issues
    were questions properly decided by the jury. The jury was free to reject the DNA
    evidence if it concluded that the evidence was unreliable or misleading.
    The appellant also argues that the evidence should have been excluded
    because its probative value was outweighed by its prejudicial effect.
    Tenn.R.Evid. 403. The appellant makes no argument in support of this
    contention. As such, this claim is waived. Tenn. R. App. P. 27(a)(7).
    26
    Nonetheless, the testimony, in sum, was that the appellant could not be
    excluded as a source of the semen found on the victim, but could not be
    identified as the source with absolute certainty. Clearly, the probative value of
    the expert testimony outweighed any prejudicial effect.
    In summary, we conclude that the trial court properly analyzed the DNA
    typing evidence according to the Tennessee Rules of Evidence. Furthermore,
    we find that the existence of scientific debate does not, by itself, require
    exclusion of evidence. The DNA statistical frequency analysis was generally
    accepted by the scientific community at all times relevant to the trial court's
    decision. Thus, the evidence exhibited both reliability and trustworthiness. The
    trial court did not abuse its discretion in admitting the calculations as to
    frequency probability, and it was for the jury to determine what weight, if any, to
    give such evidence. Additionally, we note that the State did not rely exclusively
    on the DNA evidence to prove its case. Sufficient evidence existed apart from
    the DNA analysis from which the jury could have concluded the appellant's guilt.
    This issue is without merit.
    IV. Motion to Suppress
    A hearing was held on March 1, 1994, regarding the appellant's motion to
    suppress blood samples obtained from his person. At the hearing, the State
    presented the testimony of only one witness, Larry Davis, a special agent with
    the Tennessee Bureau of Investigation. Agent Davis explained that on June 7,
    1990, the body of Vicky Sue Metzger was found in a wooded area adjacent to
    the eastbound I-24 rest area near Monteagle. Davis was assigned to investigate
    the Metzger murder. During the early stages of the murder investigation, Davis
    talked with the appellant, who was the attendant at the eastbound rest area, and
    27
    Johnny Hood, the attendant at the westbound rest area. On this occasion, Davis
    informed both men that they would be contacted in the future for additional
    statements. On July 11, Davis issued subpoenas for both men setting a July 13
    interview.
    On July 13, 1990, Agent Davis met the appellant and Hood at the Grundy
    County Jail. Both men gave sworn statements and both men consented to
    provide a blood sample for DNA comparison analysis with the semen found on
    the victim's body. The appellant and Hood were taken to Dr. Horbolt's office and
    the samples were drawn. At no time did the appellant voice an objection to the
    procedure. After the sample was drawn, the appellant left the doctor’s office.
    Subsequently, on November 5, 1992, Agent Davis was again called to the
    eastbound I-24 rest area to investigate an assault on Pamela Sue Back. When
    Davis reached the Monteagle Police Station, the appellant was in custody and
    had been provided Miranda warnings. Upon questioning by Agent Davis, the
    appellant confessed that he had assaulted Back because he had been drinking
    and smoking marijuana. Davis asked the appellant if he would provide a blood
    sample for a drug screen. The appellant again consented. The appellant was
    then transported to the Emerald-Hodgson Hospital in Sewanee where the blood
    sample was taken.25
    Several days later, Davis reviewed the I-24 incidents and the murder of
    Michelle Blake with Agent Danny Wix and Investigator Bouldin. The officers
    recalled that the perpetrator of the Blake murder had type B blood, the same
    type possessed by the appellant. Agent Wix inquired about obtaining another

    On July 17, 1990, at least seven additional TBI subpoenas were issued to area
    hos pitals requiring them to produc e na m es a nd o ther p ersona l inform ation o n wh ite m ale pa tients
    with blood type B. W e reject the appellant’s argument that this alleged dragnet approach violated
    his constitutional rights under the holding of Davis v. Mississippi, 
    394 U.S. 721
    , 
    89 S. Ct. 1394
    (1969).
    28
    blood sample from the appellant. Agent Davis responded that he had a blood
    sample from the appellant drawn on November 5 at his office. This sample was
    sent to Cellmark Diagnostics for DNA analysis in the Blake case. No alcohol or
    drug screen was performed on this sample.
    The appellant contends that the trial court erroneously denied his motion
    to suppress the evidence stemming from blood samples taken from him on these
    two separate occasions. In denying the motion, the trial court concluded that
    "the blood samples provided by the appellant were done so consensually and
    voluntarily."
    The initial inquiry before us is whether the TBI subpoena issued to the
    appellant on July 11, 1990, constituted a significant intrusion upon interests
    protected by the Fourth Amendment.26 Fourth Amendment protections against
    unlawful seizures are designed to "prevent arbitrary and oppressive interference
    by officials with the privacy and personal security of individuals." INS v. Delgado,
    
    466 U.S. 210
    , 215, 
    104 S. Ct. 1758
    , 1762 (1984) (internal quotations omitted).
    Therefore, "not all . . . intercourse between policemen and citizens involves
    seizures of persons. Only when an officer, by means of force or show of
    authority, has restrained the liberty of a citizen may we conclude that a seizure
    has occurred." Terry v. Ohio, 
    392 U.S. 1
    , 19, 
    88 S. Ct. 1868
    , 1879, n. 16 (1968).
    Although the appellant, in the instant case, received a subpoena to appear for
    further questioning, we cannot conclude that this amounted to more than a
    request to respond to police questioning. First, no sanctions exist for failure to
    comply with the request in the subpoena.27 Moreover, although most people will
    26
    Tenn. Code Ann. § 38-6-102 provides that "criminal investigators shall
    have full power to issue subpoenas for witnesses . . . ."
    27
    The subpoena received by the appellant was captioned "Tennessee Bureau of
    Investigation Su bpo ena " and provided, in pertine nt part:
    You are hereby commanded to summ on John Chapman to personally appear
    before the undersigned Special Agent of the Tennessee Bureau of Investigation
    on July 13th , 19 92, at 1:00 p m at Grundy Co. Jail, Altamont, Tennessee and
    29
    comply with a police request, the fact that people do so, and do so without being
    told they are free not to respond, does not eliminate the consensual nature of the
    response. INS v. 
    Delgado, 466 U.S. at 216
    , 104 S.Ct. at 1762. Unless the
    circumstances of the encounter at issue are so intimidating as to demonstrate
    that a reasonable person would have believed he was not free to refuse the
    officer's request, one cannot say that the questioning resulted in a detention
    under the Fourth Amendment. 
    Id. Thus, although
    we concede the question is
    perilously close, we conclude that the issuance of a TBI subpoena does not, per
    se, constitute a seizure within the meaning of the Fourth Amendment. However,
    this consensual encounter may escalate into a seizure as a consequence of
    police behavior, e.g., threatening presence of several officers, the display of a
    weapon by the officer, physical touching of the person, or the use of language or
    tone of voice indicating that compliance with the officer's request might be
    compelled. United States v. Mendenhall, 
    446 U.S. 544
    , 554-55, 
    100 S. Ct. 1870
    ,
    1877 (1980). In the present case, Agent Davis testified that the appellant came
    to the police station of his own free will. In fact, Davis had previously informed
    the appellant of his intent to contact him for a subsequent statement, at which
    time the appellant was cooperative. And, although the appellant bears the initial
    burden of showing that there was a violation of some constitutionally protected
    area to trigger further inquiry, there is no evidence indicating that the appellant
    would have refused the subsequent interview notwithstanding service of the
    subpoena. See State v. Burton, 
    751 S.W.2d 440
    (Tenn. Crim. App. 1988).
    Absent any evidence indicating force or coercion on the part of law enforcement
    officials, the inoffensive contact, i.e., the questioning of the appellant at the jail,
    cannot amount to an unconstitutional seizure. 
    Id. from day
    to day hereafter until discharged and bring all papers, books, records,
    agreements, documents and                          to be sworn and questioned by the
    und ersigned Sp ecial Agent for th e pu rpos e of g iving a w ritten sta tem ent,
    delivering aforementioned items and obtaining evidence by said agent in an
    inves tigation con duc ted by the T enn ess ee B urea u of Investigation perta ining to
    TBI File 5A-530.
    30
    Although we have determined that the appellant's presence at the jail did
    not constitute an illegal seizure, we must next determine whether the subsequent
    taking of blood samples constituted an illegal search of the appellant's person.
    The withdrawal of blood from a subject for purposes of serological typing and
    DNA analysis constitutes a search within the constraints of the Fourth
    Amendment and, therefore, a search warrant is generally required. See
    Schmerber v. California, 
    384 U.S. 757
    , 767-72, 
    86 S. Ct. 1826
    , 1833-37 (1966);
    see also State v. Jackson, 
    889 S.W.2d 219
    , 221 (Tenn. Crim. App. 1993), perm.
    to appeal denied, (Tenn. 1994). Unless it falls within a specifically established
    and well-delineated exception, a search conducted without a warrant is per se
    unreasonable. Schneckloth v. Bustamonte, 
    412 U.S. 218
    , 219, 
    93 S. Ct. 2041
    ,
    2043 (1973) (citations omitted). "One of the specifically established exceptions
    to both a warrant and probable cause is a search that is conducted pursuant to a
    voluntarily given consent." 
    Id. at 219,
    93 S.Ct. at 2043, 2044 (citations omitted);
    see also State v. Bartram, 
    925 S.W.2d 227
    , 230 (Tenn. 1996). The burden of
    proof rests upon the State to show, by a preponderance of the evidence, that the
    consent to a warrantless search was given freely and voluntarily. 
    Schneckloth, 412 U.S. at 248-49
    , 93 S.Ct. at 2059; Bumper v. North Carolina, 
    391 U.S. 543
    ,
    548, 
    88 S. Ct. 1788
    , 1792 (1968); 
    Bartram, 925 S.W.2d at 230
    . The question of
    whether the appellant voluntarily consented to the search is a question of fact
    which focuses upon the totality of the circumstances. 
    Schneckloth, 412 U.S. at 248-249
    , 93 S.Ct. at 2059.
    In the present case, the trial court accredited Agent Davis' testimony that
    the appellant voluntarily consented to providing both blood samples. There was
    no indication that the appellant's acquiescence to the "search" was the result of
    force or coercion. In fact, the defense presented no proof to refute Agent Davis'
    testimony. A trial court's finding that a search is consensual is presumed correct
    31
    and is conclusive on appeal unless the evidence preponderates against the
    ruling. State v. Woods, 
    806 S.W.2d 205
    , 208 (Tenn. Crim. App. 1990), perm. to
    appeal denied, (Tenn. 1991), cert.denied, 
    502 U.S. 1079
    , 
    112 S. Ct. 986
    (1992);
    see also State v. Dougherty, 
    930 S.W.2d 85
    , 86 (Tenn. Crim. App. 1996); State
    v. Tuttle, 
    914 S.W.2d 926
    , 931 (Tenn. Crim. App. 1995). We conclude that the
    evidence in the record supports the trial court's finding. This issue is without
    merit.
    V. Instruction on Identity
    The appellant contends that the trial court committed reversible error by
    failing to instruct the jury on the issue of identity as provided in State v. Dyle, 
    899 S.W.2d 607
    (Tenn. 1995). The appellant concedes that, because his trial
    occurred prior to the Dyle opinion, no special instruction regarding identity was
    requested.28 In Dyle, our supreme court held that the identity instruction,
    promulgated within that decision, must be given when identification is a material
    issue. 
    Dyle, 899 S.W.2d at 612
    . "Identity will be a material issue when the
    defendant puts it at issue or the eyewitness testimony is uncorroborated by
    circumstantial evidence." 
    Id. at note
    4. In our opinion, the trial court's failure to
    instruct on identity in the present case was harmless. The proof regarding
    identification was more than sufficient. The descriptions of the appellant and his
    vehicle by numerous witnesses were generally consistent. Fibers from the
    victim's clothing were determined to be consistent with fibers from the carpeting
    of the appellant's truck. Most notably, the results of the DNA profile analysis
    reveal that the appellant's DNA matched the DNA obtained from the semen stain
    on the victim's body. It was within the jury's prerogative to assess the credibility
    28
    The appellant's trial began on March 21, 1994, concluding on April 2, 1994, over one
    year prior to our supreme court's opinion in Dyle, 899 S.W .2d at 612, which was released on May
    15, 1995 . How ever, Dyle is applicable both to those cases on appeal when the opinion was
    released and to thos e ca ses tried after that date. 
    Id. 32 of
    those who testified. Any error created by the failure to provide the Dyle
    instruction was harmless. State v. Williams, No. 01C01-9505-CR-00146 (Tenn.
    Crim. App. at Jackson, Nov. 12, 1996). This contention of the appellant is
    without merit.
    VI. Scope of Cross-Examination
    Next, the appellant makes two arguments regarding the examination of
    the DNA experts from Cellmark Diagnostics. Julie Cooper, a senior molecular
    biologist with Cellmark, testified for the State. In response to defense counsel's
    questions on cross-examination, Cooper testified that, in 1988, Cellmark
    responded to an invitation extended by the California Association of Crime Lab
    Directors to bid for services to complete forensic DNA analysis for the State of
    California. Prior to being awarded the contract, Cellmark was required to submit
    analysis on unknown controlled random samples.29 During further cross-
    examination, defense counsel questioned Cooper concerning alleged errors
    made by Cellmark on the sample tests.30 On re-direct, Cooper testified that forty
    percent of Cellmark's cases originate from the State of California. She further
    explained that, in regard to the 1988 test, "California was interested in seeing
    how well Cellmark, as a laboratory, function[ed] on their test." The appellant
    argues this re-direct testimony was error. He contends that these statements
    constitute inadmissible hearsay, were made outside the scope of cross-
    examination, and are self-serving statements offered in an attempt to bolster the
    credibility of Cellmark.
    29
    Cooper testified that, unlike routine forensic testing, serological testing had not been
    performed on the test samples. Therefore, Cellmark was not informed as to whether the samples
    were blood, ketchup, etc.
    30
    Co ope r testified that "the re was o ne e rroneou s m atch m ade out of thos e 50 sam ples."
    33
    "The right to cross-examination is fundamental, thus, the denial of this
    right to apprise the accused a fair trial is 'constitutional error of the first
    magnitude.'" State v. Henning, No. 02C01-9504-CC-00115 (Tenn. Crim. App. at
    Jackson, Jan. 9, 1997) (quoting State v. Hill, 
    598 S.W.2d 815
    , 819 (Tenn. Crim.
    App. 1980)). Yet, the propriety, scope, manner and control of testimony and
    other evidence, including the scope of cross and re-direct examination, is within
    the sound discretion of the trial court, which will not be reversed absent an abuse
    of that discretion. See State v. Barnard, 
    899 S.W.2d 617
    , 624 (Tenn. Crim.
    App.), perm. to appeal denied, (Tenn. 1994) (citing State v. Banks, 
    564 S.W.2d 947
    , 949 (Tenn. 1978)); State v. Elrod, 
    721 S.W.2d 820
    , 823 (Tenn. Crim. App.
    1986); Tenn. R. Evid. 611(a).
    The scope of cross-examination extends to "any matter relevant to any
    issue in the case, including credibility." Tenn.R.Evid. 611(b). The scope of re-
    direct examination is generally limited to matters brought out during cross-
    examination, however, new matters may be introduced. Bouchard v. State, 
    554 S.W.2d 654
    , 658-659 (Tenn, Crim. App. 1977); Lundy v. State, 
    521 S.W.2d 591
    ,
    594 (Tenn. Crim. App. 1974). It is within the trial court's discretion to allow a
    party, on redirect examination, to supply testimony omitted by oversight, or to
    clarify testimony given on direct examination, or, where the facts thus developed
    34
    are not inconsistent with his previous answers to ask a witness to expand his
    testimony. 
    Barnard, 899 S.W.2d at 624
    (citing 98 C.J.S. Witnesses § 419
    (1955)); see also State v. Owen, No. 1209 (Tenn. Crim. App. at Knoxville, May
    26, 1989), perm. to appeal denied, (Tenn. Oct. 2, 1989) (citing C. TORCIA ,
    W HARTON'S CRIMINAL EVIDENCE § 416 (4th ed.)). We find no abuse of discretion
    by the trial court in permitting the introduction of Cooper’s testimony on redirect
    examination. This issue is without merit.
    Next, the appellant challenges the trial court's ruling which limited his
    cross-examination of State's witness, Dr. Lisa Forman, an expert in the field of
    DNA analysis. Forman testified that, in the present case, a Southern
    Appalachian database was not used in determining a frequency ratio. Moreover,
    in response to the challenge of "genetic inbreeding" in the Appalachian area,
    she testified that she doubted the veracity of the stereotype associated with the
    region and that, although "it would not be inappropriate to screen people from
    this area", she does not believe that inclusion of such a database would change
    the results of Cellmark's calculations. The appellant asserts that another
    Cellmark employee, Dr. Charlotte Word, testified as an expert witness in an Ohio
    courtroom that Cellmark did not employ an Appalachian database and, therefore,
    she would be very concerned about the reliability of any projections using
    Cellmark's existing databases. He argues that the trial court committed
    reversible error by not permitting him to impeach Dr. Forman with the testimony
    of her co-employee, Dr. Word. In support of his position, the appellant contends
    that "[Cellmark] was the witness and that the only authority Forman or Cooper
    had was to speak about what the lab collectively produced."
    Impeachment of an expert witness is governed, generally, by
    Tenn.R.Evid. 616 (bias or prejudice), Tenn.R.Evid. 618 (learned treatise), and
    Tenn.R.Evid. 613 (prior inconsistent statement). However, the appellant
    35
    attempts to create a right of impeachment based upon alleged conflicting
    positions of experts within the scope of their common employment. This
    argument is misplaced. Again, the trial court has the discretion to impose
    reasonable limits on cross-examination and, we will only find error when that
    discretion has been abused. See 
    Barnard, 899 S.W.2d at 624
    . In determining
    whether limitations on cross-examination of government witnesses are so severe
    as to amount to a violation of the Confrontation Clause, the reviewing court must
    ascertain "whether the jury was already in possession of sufficient information to
    make a discriminating appraisal of the particular witness' possible motives for
    testifying falsely in favor of the government."31 United States v. Christian, 
    786 F.2d 203
    , 213 (6th Cir. 1986) (citation omitted); see also United States v. Harris,
    No. 95-4356 (6th Cir. July 1, 1997). From the facts before us, we find no abuse
    of discretion or infringement of the appellant's right to confrontation. The
    proffered statements of the non-testifying witness, Dr. Word, were clearly
    inadmissible hearsay. Moreover, the expert, in this case, was Dr. Forman, not
    Cellmark Diagnostic. A business entity cannot be qualified as an expert, rather
    an individual may be qualified as an expert through his or her employment with
    that entity.32 See Tenn.R.Evid. 702. This issue is without merit.
    VII. Sentencing
    In his final issue, the appellant alleges that the trial court erred by
    imposing the maximum sentences for his convictions for aggravated kidnapping
    and aggravated sexual battery and by ordering that all three sentences be
    31
    The Confrontation Clause only guarantees "an opportunity for effective cross-
    examination, not cross-examination that is effective in whatever way, and to whatever extent, the
    defens e m ight wish." Delaware v. Fensterer, 
    474 U.S. 18
    , 20, 
    106 S. Ct. 292
    , 294 (1985) (citation
    om itted).
    32
    To be qualified as an expert, one m ust be particularly sk illed, learned, or experienced in
    a sc ience, art, trade, business , profe ssion or voca tion. Otis v. Cambridge Mut. Fire Ins. Co., 850
    S.W .2d 439 (Te nn. 1992).
    36
    served consecutively.
    Review, by this court, of the length, range, or manner of service of a
    sentence is de novo with a presumption that the determination made by the trial
    court is correct. Tenn. Code Ann. § 40-35-401(d)(1990). This presumption only
    applies, however, if the record demonstrates that the trial court properly
    considered relevant sentencing principles. State v. Ashby, 
    823 S.W.2d 166
    , 169
    (Tenn. 1991). In making our review, this court must consider the evidence heard
    at trial and at sentencing, the presentence report, the arguments of counsel, the
    nature and characteristics of the offense, any mitigating and enhancement
    factors, the appellant's statements, and the appellant's potential for rehabilitation.
    Tenn. Code Ann. §§ 40-35-102, -103(5), -210(b) (1990); see also State v. Byrd,
    
    861 S.W.2d 377
    , 379 (Tenn. Crim. App. 1993) (citing 
    Ashby, 923 S.W.2d at 168
    ). The burden is on the appellant to show that the sentence imposed was
    improper. Sentencing Commission Comments, Tenn. Code Ann. § 40-35-
    401(d).
    A. Enhancement and Mitigating Factors
    At the conclusion of the sentencing hearing, the trial court found five
    enhancement factors and three non-statutory mitigating factors applicable and
    imposed the maximum twelve year sentences for each conviction. The
    enhancing factors found are as follows:
    (a) Tenn. Code Ann. § 40-35-114(5) - The appellant treated the
    victim with exceptional cruelty;
    (b) Tenn. Code Ann. § 40-35-114(6) - The personal injuries inflicted
    upon the victim were particularly great;
    (c) Tenn. Code Ann. § 40-35-114(7) - the offense involved a victim
    and was committed to gratify the appellant’s desire for pleasure or
    excitement;
    37
    (d) Tenn. Code Ann. § 40-35-114(9) - The appellant possessed
    and employed a deadly weapon during the commission of the
    offense; and
    (e) Tenn Code Ann. § 40-35-114(10) - The appellant had no
    hesitation about committing a crime when the risk to human life
    was high.
    The trial court applied all five factors to both offenses.
    The following mitigating factors were found:
    Tenn. Code Ann. § 40-35-113(13):
    1. The appellant did not have a significant history of criminal
    convictions at the time of the present offenses;
    2. The appellant had obligations to his child; and
    3. The appellant served in the National Guard.
    The appellant contends that any factor involving bodily injury is not
    applicable to the aggravated kidnapping conviction since that element was
    necessarily included within the offense. Additionally, he argues that factor (7)
    also is not applicable to the aggravated kidnapping conviction. The State
    concedes that factor (7), committed to satisfy the appellant's desire for pleasure
    or excitement, is inapplicable to either offense. We agree.
    Initially, we note that enhancement factors cannot be elements of the
    offense charged. Tenn. Code Ann. § 40-35-114. The trial court applied factor
    (6), that the victim's injuries were particularly great, to the appellant's conviction
    for aggravated kidnapping and aggravated sexual battery. The appellant now
    argues that the court erred in applying this factor. See State v. Nix, No. 03C01-
    9406-CR-00211(Tenn. Crim. App. at Knoxville, Nov. 21, 1995); State v. Nunley,
    No. 01C01-9309-CC-00316 (Tenn. Crim. App. at Nashville, Feb. 2, 1995), perm.
    to appeal denied concurring in results only, (Tenn. May 8, 1995). Aggravated
    kidnapping, in the present case, requires that the defendant committed the act of
    "false imprisonment, as defined in §39-13-302, with the intent to inflict serious
    38
    bodily injury. . . ." Tenn. Code Ann. § 39-13-304. "Proof of serious bodily injury
    will always constitute proof of particularly great injury." State v. Jones, 
    883 S.W.2d 597
    , 602 (Tenn. 1994). Thus, factor (6) may not be used to enhance the
    appellant's sentence for aggravated kidnapping. However, aggravated sexual
    battery requires that the defendant made unlawful sexual contact with the victim
    and caused only bodily injury to the victim. Tenn. Code Ann. § 39-13-504 (a)(2).
    If the proof supports a finding that the personal injuries were particularly great,
    factor (6) is applicable to sexual battery cases. See State v. Kissinger, 
    922 S.W.2d 482
    , 488 (Tenn. 1996). The evidence establishes that the physical
    injuries to the victim were particularly great. The trial court properly applied
    factor (6) in enhancing the appellant's sentence for aggravated sexual battery.
    Accordingly, upon de novo review, we conclude that the trial court
    properly applied factors (5), the appellant treated the victim with exceptional
    cruelty, Tenn. Code Ann. § 40-35-114(5)33; (9), the appellant possessed and
    employed a deadly weapon during the commission of the offense, Tenn. Code
    Ann. § 40-35-114(9); and (10), the appellant had no hesitation about committing
    a crime when the risk to human life was high, Tenn. Code Ann. § 40-35-
    114(10),34 to both offenses. However, factor (6) is only applicable to the
    conviction for aggravated sexual battery.
    Additionally, upon de novo review, we find factor (1), that the defendant
    has a previous history of criminal convictions or criminal behavior, Tenn. Code
    33
    See Sta te v. Po ole, 945 S.W .2d 93 (Ten n. 1997).
    34
    Our supreme court held, in Jones, 883 S.W .2d at 602-603, that enhancement factor
    (10) is not inh eren t in offense s wh ere s erious bo dily injury is an e lem ent of the offense c harg ed.
    Factor (1 0) is appro priate whe re the con duc t of the pers on h as c aus ed o r incre ase d risk either to
    human life in general or to the victim in particular and risk to human life is not an element of the
    offense . State v. Fox, No. 03C01-9503-CR-00061 (Tenn. Crim. App. at Knoxville, June 21, 1996)
    (citations omitted). W e conclude that stabbing the victim m ultiple times, resulting in her death,

    Ann. § 40-35-114(1), and factor (8), that the defendant has a previous history of
    unwillingness to comply with the conditions of a sentence involving release in the
    community, Tenn. Code Ann. § 40-35-114(8), applicable to both offenses. The
    appellant was convicted of driving under the influence in 1988. He admitted to
    the use of marijuana, although he denied he had a drug dependency. See State
    v. Massey, 
    757 S.W.2d 350
    , 352 (Tenn. Crim. App. 1988). See, e.g., State v.
    Parsons, No. 01C01-9601-CC-00043 (Tenn. Crim. App. at Nashville, Jan. 30,
    1997) (criminal behavior based upon use of marijuana). After the commission of
    the instant offenses but prior to sentencing, the appellant committed and was
    convicted of driving under the influence, driving on a revoked license, and
    possession of marijuana. The appellant admitted to criminal behavior in the
    assault of Pamela Back. State v. Marshall, 
    870 S.W.2d 532
    , 542 (Tenn. Crim.
    App. 1993). This court has previously held that a sentencing court "can consider
    criminal convictions or any other criminal behavior which occurred prior to the
    sentencing hearing as constituting a previous history of criminal convictions or
    criminal behavior, regardless of whether the convictions or behavior occurred
    before or after the criminal conduct under consideration." State v. Poole, No.
    02C01-9506-CC-00178 (Tenn. Crim. App. at Jackson, Jan. 31, 1996), affirmed
    
    by, 945 S.W.2d at 93
    (Tenn. May 12, 1997) (citing State v. Waters, No. 01C01-
    9106-CR-00158 (Tenn. Crim. App. at Nashville, Feb. 20, 1992), perm. to appeal
    denied, (Tenn. June 22, 1992)). The evidence supports application of factor (1).
    Consequently, implicit within our finding that the appellant has a previous history
    of criminal convictions and behavior is our rejection of the trial court's finding, as
    a mitigating factor, that the appellant does not have a significant history of
    criminal convictions. Moreover, the record indicates that the appellant received
    suspended sentences for driving under the influence and driving on revoked
    license convictions occurring after the instant offenses. Approximately five
    months after being placed on probation, the appellant was charged with criminal
    attempt to commit aggravated burglary. Subsequently, his probation was
    40
    revoked. Accordingly, factor (8) is also applicable. See State v. Hayes, 
    899 S.W.2d 175
    (Tenn. Crim. App. 1995).
    In reference to the trial court’s finding of the non enumerated mitigating
    factor (13), “the appellant’s obligation to his child,” we hold this factor
    inapplicable as we are unable to conclude that it is “consistent with the purpose
    of this chapter.” Tenn. Code Ann. § 40-35-113(13). We find no nexus between
    paternityship and mitigation of punishment. Moreover, support of a dependent is
    by law an obligation and a duty. See Tenn. Code Ann. § 34-11-102(a) (1996).
    We find it inappropriate to reward someone for that which they are already under
    a moral and legal obligation to perform. We agree with the trial court’s finding
    that the appellant’s service in the National Guard is a proper mitigating factor. In
    sum, we find enhancing factors (1), (5), (8), (9), and (10) and one mitigating
    factor applicable to both offenses. Regarding the aggravated sexual battery
    conviction, we find the additional enhancing factor that the injuries to the victim
    were particularly great, 40-35-114(6), applicable.
    B. Length of Sentence
    The appellant was convicted, as a range I offender, of aggravated
    kidnapping and aggravated sexual battery, both class B felonies. See Tenn.
    Code Ann. § 39-13-304(b)(1); Tenn. Code Ann. § 39-13-504(b). Accordingly, he
    was subject to a sentence "not less than eight nor more than twelve years."
    Tenn. Code Ann. § 40-35-112(a)(2) (1990). The trial court imposed the
    maximum sentence, twelve years, for each offense. The appellant now
    contends that, considering the trial court's misapplication of enhancement
    factors, the court erred in imposing the maximum sentence within the range to
    his two convictions.
    41
    Regarding the length of a sentence, the presumptive sentence shall be
    the minimum sentence in the range if there are no enhancement or mitigating
    factors. Tenn. Code Ann. § 40-35-210(c). Thus, the presumptive sentence for
    the instant offenses is eight years. However, if there are both enhancement
    factors and mitigating factors, the court must start at the minimum sentence in
    the range, enhance the sentence within the range as appropriate for the
    enhancement factors, and then reduce the sentence within the range as
    appropriate for the mitigating factors. Tenn. Code Ann. §40-35-210(e).
    "The weight to be afforded mitigating and enhancement factors derives
    from balancing relative degrees of culpability within the totality of the
    circumstances of the case involved." State v. Moss, 
    727 S.W.2d 229
    , 238
    (Tenn. 1986). See also State v. Marshall, 
    870 S.W.2d 532
    , 541 (Tenn. Crim.
    App. 1993). There is no particular value "vis-a-vis how many years should be
    added or subtracted based on the presence of any of these factors." 
    Moss, 727 S.W.2d at 238
    . Thus, with the purposes of the Sentencing Act in mind, the
    sentencing court retains the discretion in determining the weight afforded to the
    applicable factors. 
    Id. at 273.
    Upon de novo review, with full consideration of
    the applicable enhancers and single mitigator, the presumptive sentence at the
    minimum of the range, and the nature and circumstances of these offenses, we
    conclude that the maximum sentences of twelve years are justified for both
    offenses. This issue is without merit.
    C. Consecutive Sentences
    Finally, the appellant contends that the trial court erred in ordering his
    42
    sentences to be served consecutively. At the conclusion of the sentencing
    hearing, the court determined that, based upon the appellant's pending charges
    for the murder of Vicky Sue Metzger and the assault of Pamela Sue Back, the
    appellant qualified as a "dangerous offender," Tenn. Code Ann. § 40-35-
    115(b)(4) (1990), and imposed consecutive sentences. The appellant contends
    that the trial court’s consideration of the pending criminal charges for purposes of
    imposing consecutive sentences was error.
    If a defendant is convicted of more than one criminal offense, the court
    may order the sentences to run consecutively provided that the defendant meets
    at least one of the criteria enumerated in Tenn. Code Ann. § 40-35-115. In the
    present case, the trial court imposed consecutive sentences based upon the
    appellant's classification as a dangerous offender. Thus, we must determine
    whether the appellant qualifies as a "dangerous offender." Tenn. Code Ann. §
    40-35-115(b)(4).
    In Gray v. State, 
    538 S.W.2d 391
    , 393 (Tenn. 1976), our supreme court
    held that "[a] defendant may be classified as a dangerous offender if the crimes
    for which he is convicted indicate that he has little or no regard for human life,
    and no hesitation about committing a crime in which the risk to human life is
    high." (emphasis added). See also Tenn. Code Ann. § 40-35-115(b)(4); State
    v. Wilkerson, 
    905 S.W.2d 933
    , 937 (Tenn. 1995). Again, the trial court relied
    exclusively upon the charges pending against the appellant in classifying him as
    a "dangerous offender." The mere fact that a charge is pending, without more,
    furnishes neither evidence of criminal conduct nor proof that the defendant is a
    dangerous offender. Thus, consideration of the pending murder indictment and
    the related charges for purposes of consecutive sentencing was improper.
    Rather, the focus remains upon the inherently dangerous nature of the instant
    offenses. 
    Gray, 538 S.W.2d at 393
    .
    43
    Notwithstanding the trial court's improper consideration of the pending
    charges, upon de novo review, we conclude that the appellant is a "dangerous
    offender." See 
    Gray, 538 S.W.2d at 393
    . The appellant forcibly abducted the
    victim from her employment, transporting her into the adjoining county. He
    committed a sexual battery upon his victim. The medical report indicates
    evidence of ligature strangulation in addition to seven stab wounds to her torso,
    resulting in death. From these facts, it is obvious that the appellant’s “behavior
    indicates little or no regard for human life and no hesitation about committing a
    crime in which the risk to human life is high.” Tenn. Code Ann. 40-35-115(b)(4).
    However, this classification alone will not justify consecutive sentencing.
    
    Wilkerson, 905 S.W.2d at 938
    . "The proof must also establish that the terms
    imposed are reasonably related to the severity of the offenses committed and
    are necessary in order to protect the public from further criminal acts by the
    offender." 
    Id. In the
    present case, we find that the aggregate sentences are
    reasonably related to the severity of the offenses and are necessary to protect
    the public from further criminal acts by the appellant. Accordingly, the
    appellant's sentences are ordered to run consecutively.
    VIII. Conclusion
    For the foregoing reasons, we affirm the judgment of convictions and the
    sentences imposed for the offenses of first degree murder, aggravated
    kidnapping, and aggravated sexual battery.
