    Appeal from the United States District Court

    (December 16, 2015)
    Before HULL, WILLIAM PRYOR, and JORDAN, Circuit Judges.
    PER CURIAM:
    Case: 15-11008     Date Filed: 12/16/2015    Page: 2 of 23
    Charles Partin appeals his convictions and 292-month sentence for one count
    of transportation of a stolen vehicle, in violation of 
    18 U.S.C. § 2312
    , and two
    counts of transportation of a minor with the intent to engage in criminal sexual
    activity, in violation of 
    18 U.S.C. § 2423
    (a). Mr. Partin raises four issues on
    appeal. First, he argues that the district court erred by admitting his pre-Miranda
    statements made to park rangers. Second, he asserts that the district court abused
    its discretion by admitting DNA evidence that showed he was the father of the
    child of the victim A.L. Third, he contends that the district court incorrectly
    denied his motion for judgment of acquittal. And finally, he claims that the district
    court erred by applying a sentencing enhancement for obstruction of justice. After
    a thorough review of the record and the parties’ briefs, we affirm.
    I
    A
    On September 3, 2012, at around 5:00 p.m., Officer Jeremy Morrison, a park
    ranger in Hamilton County, Tennessee, received a report from a park employee of
    what he believed to be a minor female performing oral sex on an adult male in a
    vehicle at a remote campsite area.            Officer Morrison, along with Officer
    Christopher Baxter and Shannon McDonald, went out to locate the vehicle and
    campsite identified by the employee.
    2
    Case: 15-11008    Date Filed: 12/16/2015    Page: 3 of 23
    Upon arriving at the campsite, Officer Morrison found Mr. Partin and A.L.,
    the victim, sitting in the vehicle described by the employee, watching a movie.
    Officer Morrison approached the vehicle, identified himself, explained why he had
    come to their campsite, and asked for their identification and A.L.’s age. Both Mr.
    Partin and A.L. responded that they had not been engaging in oral sex, and Mr.
    Partin stated, “[S]he doesn’t do that. I can’t get her to do that.” D.E. 106 at 6. Mr.
    Partin gave Officer Morrison his identification. Both Mr. Partin and A.L. said that
    she was 18, but A.L. did not have any identification.
    Officer Morrison asked A.L. to step out of the vehicle and walk up the hill
    with him so that he could get her information to verify her identity. While Officer
    Morrison took A.L. up to the patrol car where Officer McDonald was waiting,
    Officer Baxter stayed with Mr. Partin. At first, A.L. gave Officer Morrison a false
    date of birth, and he was unable to verify her identity. Eventually, however, she
    admitted that she was only 15 years old and that Mr. Partin was her step-father.
    When Officer Morrison returned to the vehicle, Mr. Partin maintained that A.L.
    was 18, that she was a friend of the family and his babysitter, and that they were at
    the park on vacation.
    Officer Morrison went back to A.L. and asked her for her legal guardian.
    A.L. provided her mother’s name but said that she did not have her phone number.
    She told Officer Morrison that he would have to contact another person, whose
    3
    Case: 15-11008     Date Filed: 12/16/2015   Page: 4 of 23
    number was in Mr. Partin’s phone, to get in touch with her mother.            While
    speaking with A.L., Officer Morrison learned that she was pregnant and that she
    and Mr. Partin had come to the park because they were running from the Alabama
    Department of Human Resources.
    Once Officer Morrison learned how to reach A.L.’s mother, he returned to
    the vehicle and told Mr. Partin that A.L.’s legal guardian would need to be
    contacted. Mr. Partin asked why A.L.’s legal guardian would need to be contacted
    if A.L. was 18, but ultimately agreed to give Officer Morrison his phone. After
    Officer Morrison retrieved the contact information, he placed the phone on the
    hood of Mr. Partin’s car, where Mr. Partin was sitting. Mr. Partin, up to this point,
    was not restrained.
    Officer Morrison asked Mr. Partin for consent to search the vehicle and the
    two tents next to the vehicle at the campsite. Mr. Partin signed a consent to search
    form. In one tent, Officer Morrison found a laundry hamper, and in the second tent
    he found male and female clothing, a bed made out of blankets, and wet towels.
    Officer Morrison did not remove any of the items from the tent. In Mr. Partin’s
    vehicle, Officer Morrison found a sex toy in a flute case. Mr. Partin claimed that it
    belonged to A.L. and was not his.
    Shortly after Officer Morrison began the search, Mr. Partin became upset,
    and began to collect the items from his campsite as if he was getting ready to leave.
    4
    Case: 15-11008        Date Filed: 12/16/2015   Page: 5 of 23
    At that point, Officer Morrison was worried that Mr. Partin was moving and
    potentially destroying evidence, and explained to Mr. Partin that he was going to
    be detained. At 7:04 p.m., almost two hours after Officer Morrison arrived at the
    campsite, Mr. Partin was patted down and handcuffed. While Mr. Partin was
    detained, no investigatory actions were taken. Officer Morrison contacted the
    Sherriff’s Office, and Detective Greg Carson, a child abuse detective, responded to
    the scene. At this time Detective Carson read Mr. Partin his Miranda rights and
    took off Mr. Partin’s handcuffs.
    Officer Morrison heard Detective Carson go over the Miranda rights with
    Mr. Partin, saw Mr. Partin sign a waiver of rights form, and heard Mr. Partin
    indicate that he understood his rights. At no point did Officer Morrison hear Mr.
    Partin request an attorney or state that he did not want to answer any questions.
    Mr. Partin was handcuffed again and transported to the police station.
    After her return to Alabama, A.L. was taken to a medical center by an
    Alabama Department of Human Resources official for an ultrasound. While she
    was filling out paperwork, Mr. Partin approached A.L., ordered her to leave with
    him, grabbed her by the wrist, and pulled her down the stairs. A.L. left with Mr.
    Partin, got in a van that her mother was driving, and subsequently switched into a
    second van. Mr. Partin told A.L. that he and A.L.’s mother had stolen the second
    van from an auto dealership. They retrieved A.L.’s siblings and began driving
    5
    Case: 15-11008     Date Filed: 12/16/2015   Page: 6 of 23
    towards Mexico to avoid the Amber Alert that they believed would go out when it
    was discovered A.L. was gone. On the drive to Mexico, Mr. Partin and A.L. had
    sexual intercourse several times, and she performed oral sex on Mr. Partin.
    Eventually, Mr. Partin and A.L.’s mother decided not to continue on to
    Mexico, and instead drove to Ohio.         While in Ohio, Mr. Partin had sexual
    intercourse and oral sex with A.L. before the FBI eventually found them and
    arrested Mr. Partin.
    B
    Prior to trial, Mr. Partin filed a motion to suppress the statements he made to
    the park rangers before he was read his Miranda rights. The magistrate judge
    recommended denying the motion to suppress and concluded that Mr. Partin was
    not the subject of a Terry stop, but rather a consensual police-citizen encounter.
    The magistrate judge alternatively found that even if Mr. Partin were deemed to be
    the subject of a Terry stop, the officers had “a particularized and objective basis for
    suspecting criminal activity, both at the time the rangers initially approached the
    vehicle and afterward.” D.E. 146 at 10.
    The magistrate judge also concluded that Mr. Partin was not effectively in
    custody during the encounter with the officers. As a result, the officers were not
    required to give him Miranda warnings.
    6
    Case: 15-11008   Date Filed: 12/16/2015   Page: 7 of 23
    First, the magistrate judge found that there was no restraint to the degree
    associated with formal arrest because there was no evidence that the officers
    blocked the campsite to prevent Mr. Partin from leaving, that they threatened or
    touched him, or indicated that he was forced to comply. The magistrate judge
    found that the tone of the encounter was generally calm and cooperative and that
    Mr. Partin freely consented to searches and willingly answered questions. In the
    magistrate judge’s view, this was not the highly intrusive coercive atmosphere that
    would require Miranda warnings.
    Second, the scope of the investigatory stop was not exceeded, and thus, did
    not mature into an arrest requiring probable cause as well as Miranda warnings
    prior to questioning. In applying a four-factor test, the magistrate judge concluded
    that (1) that the officers’ investigative techniques were quick, with minimum
    interference; (2) nothing in the record indicated that the officers were less than
    prompt in carrying out their investigation; (3) an officer’s instruction to Mr. Partin
    that he remain by his car was not overly intrusive, but rather was reasonable in
    light of the circumstances; and (4) although two hours is longer than the average
    Terry stop, in this scenerio the officers were diligent and the total amount was
    reasonable in relation to the purpose of the stop and the necessary scope of the
    investigation.
    7
    Case: 15-11008    Date Filed: 12/16/2015    Page: 8 of 23
    The district court adopted the magistrate judge’s report and denied Mr.
    Partin’s motion to suppress.
    C
    Before trial, the government filed a motion in limine stating that it would
    seek to introduce evidence of Mr. Partin’s motive and intent, including testimony
    of analysts who would testify as to two matters: the results of the DNA analysis
    performed on A.L.’s underwear found at the campsite (which contained Mr.
    Partin’s semen); and the analysis performed regarding the paternity of A.L.’s baby
    (which showed that Mr. Partin was the father).           Mr. Partin argued that the
    government should be prohibited from introducing any evidence concerning his
    sexual relationship with A.L. before the events alleged in the indictment, as well as
    any evidence concerning the paternity of A.L.’s baby. Mr. Partin argued that the
    evidence was inadmissible under Federal Rule of Evidence 403 and 404. Mr.
    Partin further argued that it was not until the paternity test results were revealed,
    which was after the indictment was issued, that he learned he was likely the father
    of the child. He alleged that he believed a person named “Eric” was the father of
    the child. Therefore, he continued, at the time of the trip to Tennessee and the
    subsequent trip to Ohio, the paternity test results were irrelevant because the
    elements of the charge were his intent and motive at the time of the trip.
    8
    Case: 15-11008   Date Filed: 12/16/2015   Page: 9 of 23
    The district court ruled that evidence as to prior sexual encounters between
    A.L. and Mr. Partin was admissible, but reserved ruling on the admissibility of the
    paternity test results until after A.L. testified. The district court instructed the
    government to not go into the DNA evidence during opening statements or during
    direct examination.
    At trial, after the government had presented A.L.’s testimony on direct
    examination—during which A.L. testified that she and Mr. Partin had sex in
    Tennessee and Ohio—Mr. Partin claimed that the government “ha[d] opened the
    door” on the matter of A.L’s past sexual partners and the possible paternity of her
    child. Accordingly, Mr. Partin argued that cross-examination in this area was
    appropriate. The district court warned Mr. Partin that if his intention was to show
    that there existed a person named “Eric” that could have been the father of the
    child, then “the DNA probably definitely comes in to show that Eric is not the
    father of this child.”   D.E. 297 at 54. During cross-examination, Mr. Partin
    questioned A.L. about Eric. Subsequently, the district court ruled that the DNA
    paternity evidence was admissible: “[T]he probative value is pretty overwhelming
    for two reasons. Number one is it refutes your implied contention that she’s lying.
    Secondly, the DNA test shows that in fact he was the father, so there’s no prejudice
    at all.” 
    Id. at 69
    .
    9
    Case: 15-11008     Date Filed: 12/16/2015     Page: 10 of 23
    At the close of the government’s case and at the conclusion of trial, Mr.
    Partin moved for judgment of acquittal, arguing that the government failed to
    prove beyond a reasonable doubt all of the elements of counts two and three. Mr.
    Partin conceded that A.L. was transported in interstate commerce and that she was
    a minor, but he denied that he transported her across state lines with the intent to
    engage in unlawful sexual activity. The district court denied each of the motions.
    The jury found Mr. Partin guilty of all three charges in the indictment.
    At sentencing, Mr. Partin objected to the PSI, which recommended a two-
    level enhancement for obstruction of justice. The district court overruled the
    objection, finding that Mr. Partin obstructed justice by lying on two occasions
    during his testimony at trial. The district court stated:
    First of all, when he denied taking A.L. out of Alabama to have sex.
    It’s clear that his intent was to have sex with A.L. in Tennessee as
    well as in Ohio, and, in fact, he did [and] . . . independently and
    separately . . . [Mr. Partin] clearly perjured himself and obstructed
    justice when he claimed that he had sex with A.L., his step-daughter,
    because she sneaked into his bed and he mistook her for an older
    woman.
    D.E. 329 at 10 (alterations added).
    Mr. Partin raises four issues on appeal. First, he argues that the district court
    erred by denying his motion to suppress his pre-Miranda statements to officers
    because the officers lacked reasonable suspicion to stop him, and even if they had
    reasonable suspicion, the stop matured into a custodial detention before he was
    10
    Case: 15-11008    Date Filed: 12/16/2015   Page: 11 of 23
    given his Miranda warnings. Second, Mr. Partin contends that the district court
    abused its discretion by admitting DNA evidence demonstrating that he was the
    father of A.L.’s child because the evidence was not relevant and because its
    prejudicial effect outweighed its probative value. Third, Mr. Partin asserts that the
    district court erred in denying his motion for judgment of acquittal because the
    government did not prove beyond a reasonable doubt that he transported A.L. out
    of state with the intent to engage in unlawful activity with her. Finally, Mr. Partin
    claims that the district court erred in applying a sentencing enhancement for
    obstruction of justice.
    II
    In reviewing the denial of a motion to suppress, legal rulings are subject to
    de novo review and factual findings are reviewable for clear error. See United
    States v. Watkins, 
    760 F.3d 1271
    , 1279 (11th Cir. 2014). We consider the evidence
    in the light most favorable to the government, which prevailed below. See 
    id.
     We
    are not restricted to the evidence presented at the suppression hearing, and may
    consider the record as a whole. See United States v. Jordan, 
    635 F.3d 1181
    , 1185
    (11th Cir. 2011). Additionally, we afford substantial deference to the district
    court’s credibility determinations, both explicit and implicit. See United States v.
    Lewis, 
    674 F.3d 1298
    , 1303 (11th Cir. 2012).
    11
    Case: 15-11008     Date Filed: 12/16/2015   Page: 12 of 23
    The Fourth Amendment protects an individual’s right to be secure against
    unreasonable searches and seizures. U.S. CONST. Amend. IV. Not all interactions
    between law enforcement and citizens, however, implicate the Fourth Amendment.
    See Jordan, 
    635 F.3d at 1185
    . Only when an officer, by means of physical force or
    show of authority, has in some way restrained the liberty of a citizen, may a court
    conclude that a seizure has occurred. See 
    id.
    There are three broad categories of police-citizen encounters for purposes of
    our Fourth Amendment analysis: (1) police-citizen exchanges involving no
    coercion or detention; (2) brief seizures or investigatory detentions; and (3) full-
    scale arrests. See United States v. Perez, 
    443 F.3d 772
    , 777 (11th Cir. 2006). With
    regard to the second category of police-citizen encounters, the Fourth Amendment
    does not prohibit a police officer in appropriate circumstances and in an
    appropriate manner from approaching a person for purposes of investigating
    possible criminal behavior, even though there is no probable cause to make an
    arrest. See Jordan, 
    635 F.3d at 1186
    .
    Pursuant to Terry v. Ohio, 
    392 U.S. 1
     (1968), law enforcement officers may
    seize a suspect for a brief, investigatory stop. Such a stop, known generally as a
    Terry stop, and can be conducted where the officer has reasonable suspicion that
    the subject was involved in, or is about to be involved in, criminal activity, and the
    12
    Case: 15-11008     Date Filed: 12/16/2015   Page: 13 of 23
    stop “was reasonably related in scope to the circumstances which justified the
    interference in the first place.” Jordan, 
    635 F.3d at 1186
    .
    Reasonable suspicion requires more than just a hunch; it demands that the
    totality of the circumstances create, at least, some minimal level of objective
    justification for the belief that the person was or is engaged in unlawful activity.
    See United States v. Blackman, 
    66 F.3d 1572
    , 1576 (11th Cir. 1995). The Supreme
    Court has firmly rejected the argument that a reasonable cause for an investigative
    stop can only be based on the officer’s personal observation, rather than on
    information supplied by another person. See Navarette v. California, 
    134 S. Ct. 1683
    , 1688 (2014). In fact, where the information received can be corroborated by
    officers, it is sufficiently reliable to create reasonable suspicion of criminal
    activity. See 
    id.
     Additionally, police may also draw on their own experience and
    specialized training to make inferences from and deductions about the cumulative
    information available to them. See United States v. Lindsay, 
    482 F.3d 1285
    , 1290–
    91 (11th Cir. 2007).     Whether reasonable suspicion exists is determined by
    considering the totality of the circumstances. See Jordan, 
    635 F.3d at 1186
    .
    We agree with the district court’s alternative finding that Mr. Partin was the
    subject of a Terry stop and there was reasonable suspicion for the officers to stop
    him. The officers had reasonable suspicion to conduct the stop based on the report
    they had received from a park employee regarding possible criminal activity and
    13
    Case: 15-11008    Date Filed: 12/16/2015   Page: 14 of 23
    their own initial observations at the scene.      We disagree with Mr. Partin’s
    argument that the stop matured into a custodial detention for which Miranda
    warnings were required. The stop did not exceed its scope, and Mr. Partin was not
    subjected to the same type of inherently coercive environment as a stationhouse
    interrogation.
    Miranda warnings are required only when a defendant is “in custody,”
    meaning that there has been either a formal arrest or a restraint on the defendant’s
    freedom of movement that is of the degree associated with a formal arrest. See
    United States v. Street, 
    472 F.3d 1298
    , 1309 (11th Cir. 2006). Whether a person is
    in custody “depends on whether under the totality of the circumstances, a
    reasonable man in his position would feel a restraint on his freedom of movement
    to such extent that he would not feel free to leave.” United States v. Brown, 
    441 F.3d 1330
    , 1347 (11th Cir. 2006) (citation omitted). Relevant factors include the
    location and duration of the questioning, the statements made during the interview,
    whether the defendant was physically restrained, and whether the defendant was
    released after questioning. See Howes v. Fields, 
    132 S. Ct. 1181
    , 1189 (2012).
    Not all restraints on a person’s freedom of movement constitute custody for
    purposes of Miranda. Courts must determine “whether the relevant environment
    present[ed] the same inherently coercive pressures as the type of station house
    questioning at issue in Miranda.” 
    Id. at 1190
    . In making that determination, we
    14
    Case: 15-11008     Date Filed: 12/16/2015   Page: 15 of 23
    have considered whether the circumstances were such that a reasonable person
    would have “believe[d] that he was utterly at the mercy of the police, away from
    the protection of any public scrutiny, and had better confess or else.” United States
    v. Acosta, 
    363 F.3d 1141
    , 1150 (11th Cir. 2004). . Because the custody standard is
    objective, the subjective beliefs of the defendant and the officer as to whether the
    defendant was free to leave are irrelevant. See Brown, 
    441 F.3d at 1347
    .
    In distinguishing between a Terry stop and an arrest, we consider four
    nonexclusive factors: “(1) the law enforcement purpose served by the detention;
    (2) the diligence with which the officers pursued the investigation; (3) the scope
    and intrusiveness of the investigation; and (4) the duration of the detention.”
    Street, 
    472 F.3d at 1306
    . In balancing these factors, we focus on “whether the
    police diligently pursued a means of investigation likely to confirm or dispel their
    suspicions quickly, during which time it was necessary to detain the defendant.”
    
    Id.
     (quotation and citation omitted).
    First, in analyzing the law enforcement purposes served by the detention, the
    most important consideration is whether the police quickly and with minimum
    interference pursued a method of investigation that was likely to confirm or dispel
    their suspicions.    See Acosta, 
    363 F.3d at 1146
    .         Here, Officer Morrison
    approached the vehicle and asked for identification to confirm the ages of the
    passengers. Given that the park employee’s report was that the female passenger
    15
    Case: 15-11008     Date Filed: 12/16/2015   Page: 16 of 23
    was young and possibly a minor, asking for identification to determine age was the
    quickest method to confirm or dispel the suspicion that A.L. might be a minor.
    Second, “we ask whether the police were diligent in pursuing their
    investigation, that is, whether the methods the police used were carried out without
    unnecessary delay.” 
    Id.
     The record indicates that the officers were diligent and
    that the methods they used did not create unnecessary delay. Although separating
    A.L. and Mr. Partin created some delay because Officer Morrison had to walk up
    and down the hill to communicate with each of them, this was necessary under the
    circumstances. Separation, and any extra time spent corroborating their stories,
    was reasonable to get the truth from A.L. about her identity and age without any
    pressure from Mr. Partin for her to lie.
    Third, “we ask whether the scope and intrusiveness of the detention
    exceeded the amount reasonably needed by police to ensure their personal safety.”
    
    Id.
     “While restriction on freedom of movement is a factor to be taken into account
    in determining whether a person is under arrest, it alone is not sufficient to
    transform a Terry stop into a de facto arrest.” 
    Id. at 1147
     (citation omitted). Until
    Mr. Partin was handcuffed, his freedom of movement was only restricted with
    regards to going up the hill to speak with A.L. Other than that, he was free to walk
    around within the vicinity of his vehicle and smoke. Restricting Mr. Partin from
    A.L. was necessary to ensure that officers could determine her age without Mr.
    16
    Case: 15-11008    Date Filed: 12/16/2015   Page: 17 of 23
    Partin’s insistence that she was 18. Additionally, Mr. Partin was in possession of
    his car keys and his cellphone the entire time. The only brief exception was when
    Officer Morrison used the phone to write down the contact information of the
    person who could be reached to find A.L.’s legal guardian.
    The “final factor is whether the duration of the detention was reasonable.”
    
    Id.
     From our discussion of the third factor, it is clear that the amount of time was
    reasonable under the circumstances of this case. Although two hours may be
    longer than a typical Terry stop, it was reasonably necessary in this case.
    In summary, the stop did not evolve into a custodial detention for which
    Miranda warnings were required because it did not exceed its scope. The district
    court did not err in denying Mr. Partin’s motion to suppress his pre-Miranda
    statements.

    Next we turn to Mr. Partin’s challenge to the admission of the DNA
    paternity evidence. We review a district court’s evidentiary rulings for an abuse of
    discretion. See United States v. Augustin, 
    661 F.3d 1105
    , 1123 (11th Cir. 2011).
    Even if the district court’s ruling constitutes abuse of discretion, however, we will
    reverse only if the error was not harmless. See 
    id.
     An evidentiary error is harmless
    unless, in light of the record as a whole, there is a reasonable likelihood that the
    error had a substantial influence on the outcome of the proceeding. See 
    id.
    17
    Case: 15-11008    Date Filed: 12/16/2015   Page: 18 of 23
    Federal Rule of Evidence 404(b) provides that although “[e]vidence of a
    crime, wrong, or other act is not admissible to prove a person’s character in order
    to show that on a particular occasion the person acted in accordance with the
    character,” such “evidence may be admissible for another purpose, such as proving
    motive, opportunity, intent, preparation, plan, knowledge, identity, absence of
    mistake, or lack of accident.” Evidence is admissible under Rule 404(b) if (1) the
    evidence is relevant to an issue other than the defendant’s character; (2) there is
    sufficient proof to enable a jury to find by a preponderance of the evidence that the
    defendant committed the act(s) in question; and (3) the probative value of the
    evidence cannot be substantially outweighed by undue prejudice, and the evidence
    must satisfy Federal Rule of Evidence 403. See United States v. Ford, 
    784 F.3d 1386
    , 1393 (11th Cir. 2015).
    Such evidence may be independently admissible if it arose out of the same
    transaction or series of transactions as the charged offense, is necessary to
    complete the story of the crime, or is inextricably intertwined with the evidence
    regarding the charged offense. See 
    id.
     Whether offered under Rule 404(b) or as
    intrinsic evidence, the district court must find that the probative value of the
    proffered evidence is not substantially outweighed by unfair prejudice and that it
    meets the other requirements of Rule 403. See 
    id.
     In reviewing a district court’s
    decision not to exclude evidence under Rule 403, we “view the evidence in the
    18
    Case: 15-11008     Date Filed: 12/16/2015   Page: 19 of 23
    light most favorable to admission, maximizing its probative value and minimizing
    its undue prejudicial impact.” United States v. Bradberry, 
    466 F.3d 1249
    , 1253
    (11th Cir. 2006).
    The district court did not err in admitting the DNA evidence establishing Mr.
    Partin as the father of A.L.’s child because it was relevant for a number of reasons.
    First, it was relevant to Mr. Partin’s motive and intent for taking A.L. to
    Tennessee. It also provided context as to why Mr. Partin took A.L. from her
    medical appointment while she was in the custody of the DHR, and why he
    attempted to flee to Mexico. Further, as the district court noted, the evidence was
    relevant to refute Mr. Partin’s implied contention that A.L. was lying about her
    relationship with him and the implication that Eric was the father of her child.
    Finally, the probative value of the paternity test was not substantially
    outweighed by any risk of unfair prejudice because there was other evidence in the
    record, to which Mr. Partin did not object, from which the jury could have found
    that Mr. Partin had a sexual relationship with his stepdaughter and inferred that he
    was the father of her child. Even assuming the district court had erred in admitting
    the paternity evidence, Mr. Partin has not demonstrated that the evidence had a
    substantial prejudicial impact on the outcome of the trial.
    IV
    19
    Case: 15-11008     Date Filed: 12/16/2015    Page: 20 of 23
    We review de novo the denial of a motion for judgment of acquittal on
    sufficiency of the evidence grounds. See United States v. Friske, 
    640 F.3d 1288
    ,
    1290 (11th Cir. 2011). In reviewing the sufficiency of the evidence, we review the
    evidence in the light most favorable to the government and draw all reasonable
    inferences and credibility choices in the government’s favor. See 
    id.
     at 1290–91.
    The evidence is sufficient if a reasonable trier of fact could find that it established
    the defendant’s guilt beyond a reasonable doubt. See United States v. Beckles, 
    565 F.3d 832
    , 840 (11th Cir. 2009).
    Federal law prohibits the knowing transportation, in interstate commerce, of
    an individual under the age of 18 with the intent to engage in criminal sexual
    activity. See 
    18 U.S.C. § 2423
    (a). To prove that Mr. Partin violated § 2423(a), the
    government had to prove that he (1) knowingly transported A.L. in interstate
    commerce; (2) A.L. was under the age of 18; and (3) Mr. Partin intended to engage
    in criminal sexual activity with A.L. See id.
    As to the element of intent, we have often noted the difficulty in establishing
    a defendant’s state of mind. See United States v. Jernigan, 
    341 F.3d 1273
    , 1279
    (11th Cir. 2003).     Given this difficulty, intent most often is inferred from
    circumstantial evidence. See United States v. Manoocher Nosrati-Shamloo, 
    255 F.3d 1290
    , 1292 (11th Cir. 2001).        Thus, where there is some corroborative
    evidence of the defendant’s guilt and the defendant testifies in his own defense, his
    20
    Case: 15-11008    Date Filed: 12/16/2015    Page: 21 of 23
    testimony may by itself establish elements of the charged offense. See United
    States v. Ellisor, 
    522 F.3d 1255
    , 1272 (11th Cir. 2008). This is especially true of
    subjective elements such as the defendant’s intent. See 
    id.
     We have also noted
    that the jury is allowed to disbelieve the defendant and to infer that the opposite of
    his testimony is true. See United States v. Pendergraft, 
    297 F.3d 1198
    , 1211 (11th
    Cir. 2002).
    Here, the government presented evidence that Mr. Partin took A.L. across
    state lines, had intercourse with her, and had her perform oral sex on him. Mr.
    Partin claimed in his trial testimony that the intention of his traveling from
    Alabama to Tennessee was for the purpose of starting a new life with his family
    and that the trip to Ohio was to allow A.L. to live with the family again and not
    with child services. But the jury was free to reject his testimony and conclude that
    it was not true. Sufficient evidence supports the jury’s finding that Mr. Partin
    acted with the requisite intent for violating § 2423(a), and the district court did not
    err in denying his motion for judgment of acquittal.
    V
    Mr. Partin’s last argument concerns the district court’s sentencing
    enhancement for obstruction. The government bears the burden of establishing the
    facts necessary to support a sentencing enhancement by a preponderance of the
    evidence. See United States v. Perez-Oliveros, 
    479 F.3d 779
    , 783 (11th Cir. 2007).
    21
    Case: 15-11008    Date Filed: 12/16/2015    Page: 22 of 23
    We review a district court’s interpretation and application of the advisory
    sentencing guidelines to the facts de novo, and review its findings of fact for clear
    error. See United States v. Barrington, 
    648 F.3d 1178
    , 1194–95 (11th Cir. 2011).
    A factual finding is clearly erroneous when, upon review of the evidence, we are
    left with a definite and firm conviction that a mistake has been made. See 
    id. at 1195
    . Additionally, we give substantial deference to the district court’s implicit
    and explicit credibility determinations concerning witness testimony. See Lewis,
    
    674 F.3d at 1303
    .
    The Sentencing Guidelines provide for a two-level enhancement if the
    defendant willfully obstructs or attempts to obstruct the administration of justice
    with regard to the prosecution of his offense of conviction. See U.S.S.G. § 3C1.1.
    Obstruction of justice includes perjury. See id., comment. (n.4(B)). In the context
    of § 3C1.1, we have defined perjury as “false testimony concerning a material
    matter with the willful intent to provide false testimony, rather than as a result of
    confusion, mistake or faulty memory.” United States v. Moran, 
    778 F.3d 942
    , 981
    (11th Cir. 2015). See also U.S.S.G. § 3C1.1, comment. (n.2).
    Mr. Partin argues that the application of § 3C1.1 constituted error. We
    disagree.
    In finding that the obstruction of justice enhancement applies, a district court
    should clearly and separately address each element of its perjury finding. See
    22
    Case: 15-11008    Date Filed: 12/16/2015   Page: 23 of 23
    United States v. Equanazi, 
    752 F.3d 912
    , 938 (11th Cir. 2014). We may, however,
    “affirm a district court’s enhancement even absent particularized findings
    regarding the defendant’s perjury so long as the district court found in general that
    the defendant’s testimony was perjurious as to material matters and the record
    supports that finding.” United States v. Hatney, 
    80 F.3d 458
    , 463 (11th Cir. 1996)
    (citing United States v. Dobbs, 
    11 F.3d 152
    , 155 (11th Cir. 1994)).
    The district court did not err in finding that Mr. Partin perjured himself on
    material matters when he denied taking A.L. out of Alabama with the intent to
    engage in criminal sexual activity. We give substantial deference to the district
    court’s decision to credit A.L.’s testimony over Mr. Partin’s regarding the sexual
    activity that occurred on the two trips, and other evidence presented at trial
    supports the district court’s finding. As such, the district court did not err in
    applying the obstruction of justice enhancement.
    VI
    For the reasons stated above, we affirm Mr. Partin’s convictions and
    sentence.
    AFFIRMED.
