    *
    This order and judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
    however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th
    Cir. R. 32.1.
    In these consolidated appeals, Defendants-Appellants Henry Peter W oody,
    Jr., and Larry W oody (collectively “Defendants,” individually “Henry” and
    “Larry”) appeal from their convictions for second-degree murder in violation of
    
    18 U.S.C. § 1111
    (a), § 1153(a) and § 2. On October 21, 2005, following a four-
    day jury trial, Defendants, who are brothers, w ere found guilty in connection with
    the stabbing death of Kenneth Tutt on the Navajo Indian Reservation in Shiprock,
    New M exico. The district court sentenced Henry to 262 months imprisonment
    and 5 years supervised release and Larry to 235 months imprisonment and 5 years
    supervised release.
    Defendants challenge their convictions on four grounds: (1) Larry argues
    there was insufficient evidence adduced at trial to support his conviction; (2) both
    Henry and Larry argue evidence was admitted at trial in violation of Fed. R. Evid.
    401 and 403; (3) Larry challenges several of the prosecutor’s remarks made
    during closing arguments; and (4) Henry argues the district court erroneously
    imposed a special condition on his supervised release without giving prior notice
    pursuant to Fed. R. Crim. P. 32(h). Exercising jurisdiction pursuant to 
    28 U.S.C. § 1291
     and 
    18 U.S.C. § 3742
    (a), we reverse both convictions -- Larry’s due to
    insufficient evidence and Henry’s due to the erroneous admission of evidence
    substantially prejudicial to his defense.

    I. Background
    In the early morning hours of April 26, 2004, Kenneth Tutt’s body was
    discovered under a tree behind the City M arket in Shiprock, New M exico. The
    area in which Tutt’s body was discovered is known to be frequented by transients.
    It was later determined that the cause of Tutt’s death was a stab wound to the left
    side of his neck.
    On February 25, 2005, a federal grand jury returned a second superseding
    indictment charging Defendants with the second-degree murder of Tutt. After the
    district court denied the government’s motion to sever, trial commenced on
    October 17, 2005, and ended on October 20, 2005. The jury returned guilty
    verdicts against Defendants the following day. In sentencing Defendants, the
    district court imposed, without notice, a condition of supervised release that both
    Defendants submit to suspicionless searches of their property and persons
    whenever requested by law enforcement.
    Because we must review the record for sufficiency of the evidence in
    Larry’s appeal and for the admission of unfairly prejudicial evidence in H enry’s
    appeal, w e recount in some detail the pertinent portions of the trial testimony.
    Prosecution witness, Officer Brenda Harrison with the Navajo Nation Department
    of Law Enforcement, was the first officer to arrive on scene after Tutt’s body was
    discovered on April 26. She observed a pair of broken sunglasses and a baseball
    cap near the body. She also observed blood splatters on the tree branches near
    -3-
    Tutt’s head. She and another officer did not locate any other evidence in the area
    surrounding the crime scene. Harrison also testified she was familiar with
    D efendants prior to Tutt’s death and both of them usually carried backpacks. A t
    some point during the investigation of the crime scene, the authorities received
    information from Nelvis Dawes, a man w ho resided between 100 and 200 yards
    from where Tutt’s body was found, that led them to focus their attention on
    Defendants. The information gleaned from Dawes also led police to the property
    of Barbara Litson for the purpose of searching a shack occupied by Paul Hayes,
    Jr. A t around 11:00 a.m., the authorities received permission from Litson to
    search the shack, and, based on something they found during the search, the shack
    was secured until a search warrant could be obtained.
    George Joe, the individual who called law enforcement to report the
    discovery of Tutt’s body, testified next. He explained a friend had informed him
    there w as a body behind the C ity M arket. Joe also testified that he had known
    Defendants for three or four years and had seen them in the vicinity of the City
    M arket in the early afternoon on April 25. He described how Larry typically
    wore blue jeans, tennis shoes, sunglasses that fold over the eyes, and a cap.
    Henry typically wore square sunglasses, a light blue jacket, blue jeans, and tennis
    shoes. Later, during cross-examination, Joe confirmed Henry was wearing a light
    blue windbreaker on April 25, the day before the body was discovered.
    Phillip Joe, the second law enforcement officer to arrive on scene after
    -4-
    Tutt’s body was discovered, testified to observing broken wrap-around style
    sunglasses near the victim and described the general area around the body as
    “somewhat trashy.” (R. Vol. IX at 59.) He explained the Hayes shack was
    located right next to the street and was “pretty simply put together with numerous
    rough material, lumber, bark wood, plywood, and the front of the shed was or the
    entrance was unsecured.” (Id. at 67.) Hayes was not in the shack at the time of
    the search. Next, Officer Joe detailed how he searched the shack and discovered
    what appeared to be a bloody steak knife within a cupboard. On redirect
    examination, Officer Joe testified that, at the time of the search, he also noticed a
    portion of a blue jacket with reflective tape on it stuck behind a mattress. Later
    in the trial, Officer Joe claimed a jacket seized from Henry follow ing his arrest
    was similar to the blue jacket he had seen in the shack on April 26.
    Shirley Hayes, Paul Hayes’s aunt, who also lives on the property with
    Litson, testified as follows: Hayes was indeed living in the shack on April 25;
    Defendants were staying at the shack on the afternoon of April 25; and food from
    a birthday party was sent out to them at around 4:00 p.m. She opined that Henry
    always w ore a light or dark blue windbreaker, Larry always w ore a blue and white
    jacket, and both of them always carried backpacks.
    Litson was called next and testified that when she returned home from Las
    Vegas, Nevada, on the evening of April 25, nobody was at the shack. She
    confirmed, however, that sometime before 10:00 a.m. on the morning of April 26
    -5-
    she saw Defendants walking near the shack and both were holding bags.
    Dawes was next. He said Defendants had been in the Shiprock area in the
    month and a half preceding Tutt’s death. He observed the following on the
    evening of April 25:
    And I seen a bunch of people w alking as a group, and there was this
    one individual that they w ere kicking, and he kept falling down. He
    would get up, and they would kick him again. And then the taller one
    would eventually help him up, and it seems like he was getting his hits
    in at the same time, too. And he would get up again, and he would
    kick him down again. And finally, they just kept on doing that, and
    they just kept on walking.
    (R. Vol. X at 165.) Dawes recalled a total of six individuals in the group— the
    victim of the beatings, the two individuals inflicting blow s, and three observers
    who were just following. He thought nothing of the incident because fights
    happen all the time in that area of Shiprock; he turned away to return to his work.
    W hen he looked outside again a half an hour later, he saw nothing. Dawes
    identified Henry as the individual kicking the victim and Larry as the individual
    hitting the victim, but did not testify he ever observed a weapon in the hands of
    either. W hen the prosecution showed Dawes the shirt Tutt was found wearing
    when his body was discovered on April 26, Dawes confirmed the victim of the
    beatings he observed was wearing the same shirt. On cross-examination, Dawes
    admitted the only way he even recognized Larry was by his height, and claimed
    that Larry was hitting the victim with only his right hand.
    Next, the government called four expert witnesses to discuss the scientific
    -6-
    evidence (or lack thereof). First, Sandra Koch, a forensic examiner in the trace
    evidence (hairs and fibers) unit of the FBI, testified she could not match any hairs
    from Tutt to those found on the items seized from Henry’s backpack. Lora J.
    Gioeni, a forensic examiner in the mitochondrial DNA unit at the FBI, testified
    that, based on DNA testing, Tutt could be excluded as a possible source of a hair
    found on Henry’s backpack. Julie Ann Kidd, a DNA and serology (the study of
    bodily fluids) examiner with the FBI, testified she performed DNA testing on
    H enry’s boots, a jacket, a pair of pants, a t-shirt, and a backpack. Tutt’s DNA
    was not found on any of these items. Nor was either Defendants’ DNA found
    under Tutt’s fingernails. DNA extracted from blood found on the handle and
    blade of the knife located in Hayes’s shack matched Tutt’s D NA to a reasonable
    degree of scientific certainty but no latent fingerprints— from Defendants or
    anyone else— were found on the knife.
    The government’s final scientific expert was D r. Jeffrey Nine, the forensic
    pathologist who performed an autopsy on Tutt. According to D r. Nine, Tutt’s
    blood-alcohol level was .142 at the time of his death. Dr. Nine testified the cause
    of death was a stab wound “on the left side of the neck just above like the
    collarbone area, and that penetrated about two and a half inches into the neck
    tissues both perforating and penetrating a couple of major blood vessels, the
    cephalic artery and carotid artery, resulting in a lot of blood loss . . . .” (Id. at
    265-66.) Tutt also exhibited a number of other injuries (mostly scrapes and
    -7-
    bruises), including a superficial knife wound to the neck. In Dr. Nine’s opinion,
    both of the stab wounds to Tutt’s neck were consistent with having been inflicted
    by a knife like the one found in H ayes’s shack. He admitted during cross-
    examination, however, an inability to determine whether the wound was inflicted
    by a right-handed or left-handed assailant. He also estimated Tutt would have
    lost two and a half quarts of blood before he died.
    The next witness for the government was Paul Hayes who was not an eager
    witness. The government secured his presence by arrest for failing to comply
    with a subpoena. W hen he was called as a witness, prior to any questioning, the
    trial court addressed Hayes as follows: “Now, you have been given the oath, and
    you have promised to tell the truth. Do you understand that?” (R. Vol. XI at
    329.) N o other w itness was addressed in this manner.
    Hayes began his testimony by explaining that on April 25, 2004, he was
    living in the shack on Litson’s property, but did not see Defendants that
    afternoon. He went on to testify: (1) he spent the night in the shack on April 25th
    but did not remember seeing either Henry or Larry; (2) his father and a female
    friend also spent the night at the shack on April 25, but they left the next morning
    around 7:00 or 8:00 a.m.; and (3) he did not see D efendants in the morning either.
    He then offered this description of the shack:
    I can tell you this. Over at my dad’s house, we have no door. W e use
    a curtain for a door. And on the other side is a car hood, and we chain
    it up, and then we leave. Sometimes w e come back, and the door’s
    -8-
    already opened again.
    (Id. at 340.)
    Hayes was interviewed by FBI Agent W illiam Hall on April 29, three days
    after Tutt’s body was discovered. W hen Hayes testified he could not remember
    what he said to Agent Hall, the court allowed him to silently read Hall’s report to
    refresh his memory. Due to a concern Hayes may have difficulty reading the
    report in English, the court called a translator to read the report to Hayes in
    Navajo. 1 After Hayes stated he understood the substance of the report, the
    government renew ed its questioning as follow s:
    Q:       And this is a statement that you gave to M r. Hall and M r. Deale at
    the BIA office, do you recollect that?
    A:       Yes.
    ....
    Q:       Okay. Now . . . I’m going to ask you about the statement at the
    bottom . . . of Page 1, the last sentence. Do you remember making
    that statement?
    A.       No.
    Q.       Do you remember the agent asking you about Henry W oody?
    A.       No.
    Q.       Okay. Do you remember telling the agent that Henry W oody stutters
    1
    The record is not clear whether the translator read the report to Hayes
    within the hearing of the jury, but unless the jurors understood the Navajo
    language, it would not matter.
    -9-
    when he gets scared?
    A:     No.
    ....
    Q:     D o you remember telling the agent that you saw Henry W oody two
    days after M r. Tutt’s death, on the 28th?
    A:     No.
    Q:     And do you remember telling him that Henry W oody told you not to
    say anything?
    A:     No.
    Q:     You don’t remember that?
    A:     No.
    Q:     Do you remember telling me this morning that when Henry W oody
    gets nervous, that he stutters?
    A:     No.
    Q:     Do you remember talking to me downstairs this morning about 7:30
    a.m. . . . ?
    A:     Yes.
    Q:     But you don’t remember telling me that?
    A:     No.
    (R. Vol. XI at 347-48.) The court then intervened (with the jury present) 2 :
    2
    “In jury cases, proceedings shall be conducted, to the extent practicable,
    so as to prevent inadmissible evidence from being suggested to the jury by any
    means, such as making statements or offers of proof or asking questions in the
    hearing of the jury.” Rule 103(c). Federal Rules of Evidence. A judge’s
    -10-
    The Court: M r. Hayes, do you understand the questions that the law yer is
    asking you?
    The W itness:       No.
    The Court: Look at me when I talk to you. You took an oath this morning
    to tell the truth. Do you understand that?
    ....
    The Court: You sw ore to tell the truth, you promised to tell the truth
    as to all questions that . . . would be asked.
    The W itness:       Yes.
    The Court: I have concerns that you are not honoring . . . that oath. M r.
    Hayes, what is it about the questions that you do not
    understand? Tell me.
    The W itness:       I understand everything. There’s some things that’s
    written there. I don’t think I said those things.
    (Id. at 349.) W hen further questioning received the same type of response, the
    jury was sent on break. The court again admonished Hayes regarding his
    evasiveness and warned he was treading close to contempt.
    Still outside the presence of the jury, the government suggested Hayes was
    afraid of the Defendants and his fear was the source of his contrived lack of
    memory. The court questioned Hayes regarding this suggestion, but Hayes denied
    being afraid or receiving any threats from the Defendants. Henry objected to the
    form of the government’s questioning. The court responded to the prosecutor, “I
    suggestion that a witness is not being truthful would seem to be best made outside
    of the jury’s presence.
    -11-
    do have concern w ith the amount of detail here that you are noting, [counsel],
    with respect to the substance of the statements that you have.” (Id.) The
    prosecution replied, “Your Honor, just so the Court is aware, the reason I’m doing
    or going into detail because my intention is to call Agent Hall and get these
    [statements in] under the Rules of Evidence . . . prior inconsistent [statements] . .
    . .” (Id.) There was no further discussion and the jury returned to the courtroom.
    The questioning resumed in the same form. After several minutes, the
    court spoke to the jury, stating:
    [L]et me just remind the jurors. Some of the earlier instructions that
    I have given, which I will give from time to time again throughout
    the course of this trial, you are to determine the facts solely from the
    evidence admitted in this case. The evidence consists of the
    testimony of witnesses and the exhibits that are received in evidence.
    Questions asked by the lawyers are not evidence, for the evidence
    consists of the witnesses’ answers to the questions, not the questions
    themselves. Let us continue.
    (Id. at 360-361.) Eventually, the government reached the point where it tried to
    elicit Hayes’s reported statement to A gent Hall describing the Defendants’
    conduct when they drink or get angry. It inartfully asked, “A nd what, in fact, did
    you tell the agent about Larry W oody when they [sic] get mad?” (Id. at 363.)
    Henry objected alleging the statement was irrelevant and unduly prejudicial under
    Rule 403. The court did not address Rule 403 but, rather, told the prosecutor to
    lay a better foundation and ruled it would permit the question. These questions
    followed:
    -12-
    Q          Now, so when you made this statement about how they act
    when they get mad, what made you tell the agent that?
    A          W ell, like I said, what Larry does is when he gets mad and then when
    we try to joke around, he just gets mad and hits me or some other
    people there. Then he hits them, too.
    Q.         And then did you tell the agent that he talked about killing people
    when he gets mad?
    A.         That, I don’t remember.
    (Id. at 366.) 3
    Agent Hall was the government’s final witness. Assigned to investigate
    Tutt’s murder, Hall responded to the crime scene early on April 26 and at
    approximately 11:00 a.m. he was informed of the search of Hayes’s shack and the
    discovery of the bloody knife. In response, he prepared a search warrant and
    affidavit, and after obtaining a search warrant, seized the knife. He next
    described how he interviewed Henry in Cortez, Colorado, a couple of weeks after
    the murder. During that interview , Henry claimed he had heard about Tutt’s
    death on the radio and then spontaneously volunteered, “I’m innocent. I don’t
    even know that guy.” (Id. at 88 (quotations omitted)). Henry later referred to Tutt
    as Ken, leading Agent Hall to believe Henry had indeed known Tutt.
    Henry eventually admitted to Agent Hall during the interview that on April
    3
    Perhaps realizing he had focused solely on Larry, the prosecutor later
    attempted to re-ask the question by stating, “[The report] says, ‘W hen Larry and
    Henry get together and drink, they threaten,’” but the court sustained an objection
    on the basis the question had been asked and answered. (R. Vol. X I at 367.)
    -13-
    25 he had been drinking with Tutt behind the City M arket. W ith regard to the
    moment when Tutt was stabbed, Henry advised Hall, “he got up and bent over,
    and it happened really fast.” (Id. at 390.) Henry claimed that after the stabbing
    he went back to Hayes’s shack and fell asleep. Henry described the murder
    weapon “as a fixed blade hunting style knife with a four-inch blade [and] a black
    handle.” (Id. at 391.)
    Agent Hall detailed two interviews he conducted with Larry, during which
    Larry also admitted to being with Tutt on the day he was slain. Larry claimed
    that on April 25 he encountered Tutt, who requested that Larry go into the City
    M arket and purchase some “ocean” 4 for them to consume. After Larry purchased
    mouthwash and gave Tutt his change, the two drank “ocean.” Larry claimed he
    then went back to Hayes’s shack and spent the night. W hen confronted
    specifically about Tutt’s death, Larry blurted out, “I didn’t stab him or I w ould
    have blood all over my jeans.” (Id. at 395 (quotations omitted).)
    The government then moved to Hayes’s statements to Hall regarding
    Defendants’ propensity for violence when drinking. Because Hayes denied
    making the statements, the government was allowed to elicit impeachment
    testimony from Agent Hall. Hall testified Hayes told him, “‘[W hen Henry and
    4
    “Ocean” is a substitute for alcoholic beverages which are unavailable on
    the Navajo Reservation. It is created by diluting either mouthwash or hairspray
    with water. The mixture is then consumed and, apparently, can be the equivalent
    of consuming 80 proof liquor.
    -14-
    Larry] get mad, they talk about killing people’ and [Hayes] went on to say, ‘W hen
    they get together and drink, they also threaten people.’” (Id. at 402.) W hen the
    jury returned from lunch, the court properly instructed the jury that such evidence
    was admissible only to impeach the credibility of the witness and not to establish
    the truth of H ayes’s statements.
    On cross-examination, Hall testified that, at the time of his first interview
    with Larry on April 28, Larry’s right hand was extremely swollen (his fingers
    were twice the normal diameter) and he had sutures on one of his fingers. Larry
    told Hall he had surgery on his right hand in early April, a fact Hall
    independently corroborated through medical records. Hall admitted he had
    previously testified before a grand jury saying: “It’s my belief, based on what I
    saw of Larry W oody’s hand, that he could not have stabbed someone.” (Id. at 422
    (quotations omitted).) After evaluating the crime scene, Hall believed the
    assailant was right-handed and Larry would not have been able to make a fist
    without injuring the surgery wound. Hall further testified that, during a prior
    investigative interview, Dawes had said four of the five men he saw on April 25
    were kicking Tutt, but that one individual— who was wearing a blue jacket, black
    pants, and black plastic wrap-around sunglasses— did most of the pushing and
    kicking.
    At the conclusion of Hall’s testimony, the government rested and
    Defendants moved for judgments of acquittal. The judge denied the motions,
    -15-
    finding sufficient evidence as to each element of the charged offenses. The
    Defendants chose not to put on any evidence. Following jury instructions and
    closing arguments, the case was submitted to the jury.
    Larry now argues the government presented insufficient evidence from
    which a reasonable jury could find he caused Tutt’s death. Larry also takes issue
    with several of the prosecutor’s statements made during closing argument,
    including one suggesting he might have enjoyed killing the victim “in a primitive
    and human recreational kind of way thinking that he would never be in front of
    you guys [the jury].” (R. Vol. XII at 486.) Both Larry and Henry contend the
    district court committed reversible error when it allowed the prosecutor to
    question Hayes and Agent Hall regarding Hayes’s prior statements that the
    Defendants get violent and threaten to kill people when drinking and angry.
    Finally, Henry argues the court erred in attaching the suspicionless search
    condition upon his supervised release without first giving notice pursuant to Fed.
    R. Crim. P. 32(h).
    II. Discussion
    A.    Introduction
    Since Henry and Larry were co-defendants much of the evidence was
    overlapping. W e take care to delineate the scope of our review with regard to
    each of the brothers because Larry briefed and argued insufficiency of the
    evidence, but Henry did not. Henry has waived any such argument as a result of
    -16-
    his failure to raise and brief the issue. See State Farm Fire & Cas. Co. v. M hoon,
    
    31 F.3d 979
    , 984 n.7 (10th Cir. 1994) (failure to raise an issue in the appellate
    brief waives that issue).
    B.    Larry W oody
    W e begin and end our discussion of Larry’s appeal by addressing the
    sufficiency of the evidence. The requirement for the government to prove each
    essential element of a crime beyond a reasonable doubt is of immense importance
    in our criminal justice system. See In re W inship, 
    397 U.S. 358
    , 363-64 (1970)
    (“a society that values the good name and freedom of every individual should not
    condemn a man for commission of a crime when there is reasonable doubt about
    his guilt”). A ccordingly, we review the sufficiency of the evidence de novo.
    U nited States v. V oss, 
    82 F.3d 1521
    , 1524-25 (10th Cir. 1996). In so doing, we
    must “view[] the evidence in the light most favorable to the government” and ask
    whether “any rational trier of fact could have found the defendant guilty of the
    crime beyond a reasonable doubt.” United States v. Vallo, 
    238 F.3d 1242
    , 1247
    (10th Cir. 2001); accord Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979). The
    discretion to resolve conflicting testimony, weigh the evidence, and draw
    inferences from basic facts to ultimate facts lies with the jury. United States v.
    Nieto, 
    60 F.3d 1464
    , 1469 (10th Cir. 1995). On the other hand, the evidence
    relied upon to support a conviction must be substantial and raise more than a mere
    suspicion of guilt . United States v. Jameson, 
    478 F.3d 1204
    , 1208 (10th Cir.),
    -17-
    cert. denied, ___ S.Ct. ___, 2007 W L 300493 (2007) . Inferences may be
    properly drawn from the evidence but, to be reasonable, an inference must be
    based on more than mere conjecture and speculation, United States v. Atencio,
    
    435 F.3d 1222
    , 1232 (10th Cir.), cert. denied, 
    126 S.Ct. 2310
     (2006), and the jury
    is not permitted to arrive at a guilty verdict by piling inference upon inference,
    Jameson, 
    478 F.3d at 1208
    .
    To convict of second-degree murder under 
    18 U.S.C. §§ 1111
    (a) and
    1153(a), the government must show the defendant (1) is American Indian (2) who
    killed the victim (3) unlawfully (4) with malice and (5) committed the crime
    within Indian Country. See United States v. Visinaiz, 
    428 F.3d 1300
    , 1306 (10th
    Cir. 2005), cert. denied, 
    546 U.S. 1123
     (2006). All parties concede Defendants
    are Indians and Tutt, also an Indian, was killed in Indian Country. Indeed, the
    only element with which Larry takes issue, and we think correctly, is whether the
    evidence was sufficient to convict him. See United States v. Sw allow, 
    109 F.3d 656
    , 659 (10th Cir. 1997) (“Proximate cause of death is an essential component of
    both first-and second-degree murder.”).
    Both Henry and Larry denied involvement; neither self defense nor any
    other type of justification was at issue. Thus, the primary question is whether the
    evidence submitted to the jury was sufficient to prove beyond a reasonable doubt
    Larry killed Tutt or whether he aided and abetted the murder.
    Upon close examination of the testimony and evidence adduced against
    -18-
    Larry, we conclude no rational trier of fact could have found him guilty of
    second-degree murder beyond a reasonable doubt. While there was certainly
    evidence indicating he was involved (along with others) in an assault of Tutt, the
    cause of death was not the assault, but rather a stabbing. Even viewed in the light
    most favorable to the government, the evidence simply does not sufficiently link
    Larry with the stabbing. The jury could have concluded the Defendants stayed at
    Hayes’s shack the night before the murder weapon was found there. But the
    evidence also demonstrates the murder weapon was not discovered for over
    twelve hours after the stabbing allegedly occurred, at least three other
    individuals— Paul Hayes, Jr., his father and his father’s girlfriend— stayed at the
    shack on the night of April 25, and the shack was freely accessible to all who
    wished to enter.
    The lack of forensic evidence connecting Larry to the killing is also
    noteworthy. The forensic pathologist stated Tutt lost large amounts of blood,
    probably two to two and a half quarts, and significant bleeding would have
    occurred given the nature of the injuries. Indeed, the testimony revealed that
    blood had covered surrounding tree branches, and yet authorities did not find any
    of Tutt’s blood on Larry’s clothing or the backpack he constantly carried. Neither
    could the government establish the time of death. The FBI also did not find any
    trace evidence from Tutt (i.e. hairs or fibers) on Larry’s possessions and did not
    find any of Larry’s DNA on Tutt. Lastly, the FBI found no fingerprints on the
    -19-
    steak knife.
    The most damning bit of evidence against Larry is, of course, Daw es’s
    testimony -- he observed Henry (described as “the shorter [man]”) and Larry
    (described as “the taller [man]”) kicking and punching a man matching Tutt’s
    description around dusk on April 25. (R. Vol. X at 166.) Despite the great
    distance from which Dawes made these observations and the inconsistencies in
    his statements regarding the number of individuals participating in the assault, w e
    must assume his testimony is true and he did indeed see the Defendants hitting
    and kicking Tutt that evening. But while that fact incontrovertibly establishes
    battery of Tutt by the Defendants, it does not, without more, provide sufficient
    evidence to convict Larry of second-degree murder. Notably, Dawes never
    testified he saw a weapon of any sort, let alone a steak knife. M oreover, the
    exculpatory evidence regarding the physical state of Larry’s right hand only two
    days after the killing must function into the equation and Larry only confessed to
    buying and drinking “ocean” with Tutt, hardly an admission to second-degree
    murder.
    Larry’s spontaneous statement to Agent Hall is insufficient to lift the
    government’s case over the threshold of reasonable doubt. He told Hall, “I didn’t
    stab him or I would have blood all over my jeans.” (R. Vol. XI at 395 (quotations
    omitted).) W e are somewhat baffled by the government’s argument that this
    exculpatory statement is overt evidence of guilt. Even false exculpatory
    -20-
    statements (which the government did not prove this was) cannot be considered
    by the jury as direct evidence of guilt. See United States v. Davis, 
    437 F.3d 989
    ,
    996 (10th Cir.), cert. denied, 547 U .S. 1122 (2006). Viewed in the light most
    favorable to the government, Larry’s statement is not sufficiently inculpatory,
    even when combined with drinking “ocean” and participation in the assault on
    Tutt, to establish guilt beyond a reasonable doubt. 5
    M oreover, Agent Hall admitted he did not believe Larry could have stabbed
    Tutt given the physical condition of his right hand at the time of the April 28
    interview. He described the hand as extremely swollen, sutured, and bandaged
    and independently confirmed that Larry underwent hand surgery on April 10. Not
    only does this evidence cast some doubt on Dawes’s testimony— he claimed he
    saw Larry hitting Tutt with his right hand— but it further erodes the already thin
    evidence in this record suggesting Larry might have killed Tutt.
    Although the government is not required to present evidence which
    5
    Even if, viewing the evidence in the light most favorable to the
    government, the jury could find that portions of Larry’s exculpatory statements
    were false, we agree with the Second Circuit that:
    falsehoods told by a defendant in the hope of extricating himself from
    suspicious circumstances are insufficient proof on which to convict
    where other evidence of guilt is weak and the evidence before the
    court is as hospitable to an interpretation consistent with the
    defendant’s innocence as it is to the Government’s theory of guilt.
    United States v. Johnson, 
    513 F.2d 819
    , 824 (2d Cir. 1975).
    -21-
    eliminates all possible hypotheses of innocence, “readily available inferences of
    innocence” must be factored into our determination of w hether a reasonable jury
    could find a particular defendant guilty of the crime charged beyond a reasonable
    doubt. M aldonado v. Scully, 
    86 F.3d 32
    , 37 (2d Cir. 1996) (Oakes, J.,
    dissenting). Suffice it to say that the evidence brought forth at trial, even when
    view ed in toto and in the light most favorable to the government, is insufficient to
    establish Larry’s guilt beyond a reasonable doubt.
    A comparison of the evidence against Larry with that presented in United
    States v. Vallo, is instructive. 
    238 F.3d 1242
     (10th Cir. 2001). In that case, we
    held the evidence was sufficient to support the defendants’ (a mother for aiding
    and abetting and her boyfriend as a principal) second-degree murder convictions
    for the death of an infant. 
    Id. at 1247-49
    . Although the type and quantity of
    evidence adduced in Vallo is by no means the minimum required to convict for
    second-degree murder, it is nonetheless illustrative. The evidence indicated the
    defendants had repeatedly assaulted the child on the date of his death and in the
    past (the defendants, in fact, admitted to doing so), and the expert medical
    testimony established the infant died from a recent combination of shaking and
    blunt force trauma. The evidence presented in Vallo— clear admissions of
    assaulting an infant (something which is, in and of itself, sufficient to cause
    death) coupled with scientific evidence and consistent past behavior— was vastly
    stronger than the evidence the jury took under consideration in the instant case.
    -22-
    Unfortunately, there are few other reported federal decisions addressing the
    sufficiency of the evidence presented in second-degree murder trials. W e have
    located, however, a factually analogous state court decision. In State v. W hite,
    
    235 S.E.2d 55
     (N.C. 1977), the N orth Carolina Supreme Court concluded there
    was insufficient evidence to support the defendant’s second-degree murder
    conviction. 
    Id. at 59
    . The jury heard evidence in the case that the victim had
    lived in a mobile home adjacent to a motel where the defendant resided, the
    defendant frequently visited the victim, the defendant was a black male and a
    black male was seen running away from the mobile home on the evening of the
    killing, there was blood found on the carpet of the defendant’s motel room, and a
    knife similar to the murder weapon was found in the defendant’s motel room. See
    
    id. at 56-58
    . In reversing the trial court’s refusal to grant the defendant’s motion
    for non-suit, the North Carolina Supreme Court reasoned:
    [t]he State has shown that the defendant was in the general vicinity of
    the deceased’s home at the time of the murder and that he made
    several arguably contradictory statements during the course of the
    police investigation. It may even reasonably be inferred that the
    defendant was at the home of the deceased when the deceased came to
    her death, or shortly thereafter. Thus, the State has established that the
    defendant had an opportunity to commit the crime charged. Beyond
    that we must sail in a sea of conjecture and surmise. This we are not
    permitted to do.
    
    Id. at 59
     (internal citations and quotation marks omitted). This reasoning applies
    equally here.
    The government, however, also relies upon an aiding and abetting theory.
    -23-
    Pursuant to 18 U .S.C. § 2(a), “[w ]hoever . . . aids, abets, counsels, commands,
    induces or procures [the] commission [of a crime] is punishable as a principal.”
    The federal aiding and abetting statute does not establish a separate crime but
    merely eliminates “the common law distinction between principal and accessory.”
    United States v. Langston, 
    970 F.2d 692
    , 705-06 (10th Cir. 1992). Regardless,
    “one cannot aid and abet a completed crime.” United States v. Ledezma, 
    26 F.3d 636
    , 642 (6th Cir. 1994). A conviction based upon an aiding and abetting theory,
    therefore, requires the government to prove:
    (1) that the defendant associated [himself] with a criminal venture; (2)
    that the defendant participated in the venture as something [he] wished
    to bring about; (3) that [he] sought by [his] actions to make it succeed;
    and, lastly, (4) that the proof establishes the commission of the offense
    by someone and the aiding and abetting by the defendant so charged.
    United States v. Lee, 
    54 F.3d 1534
    , 1540 (10th Cir. 1995). “Although knowledge
    a crime is being committed is relevant, some showing of intent to further the
    criminal venture must be introduced at trial.” United States v. Delgado-Uribe,
    
    363 F.3d 1077
    , 1084 (10th Cir. 2004); see also United States v. Hanson, 
    41 F.3d 580
    , 582 (10th Cir. 1994) (“A defendant may not stumble into aiding and abetting
    liability by inadvertently helping another in a criminal scheme unknown to the
    defendant.”).
    The government’s case is not salvaged by its aiding and abetting theory.
    Aiding and abetting requires a defendant to “willfully associate himself with the
    criminal venture and seek to make the venture succeed through some action of his
    -24-
    own.” United States v. Leos-Quijada, 
    107 F.3d 786
    , 794 (10th Cir. 1997); see
    also United States v. Sarracino, 
    131 F.3d 943
    , 946 (10th Cir. 1997) (discussing
    the required elements of a conviction under an aiding and abetting theory). In
    other words, “[t]he aider must have the mens rea to bring about the result
    comm itted by the other principals.” United States v. Cooley, 
    1 F.3d 985
    , 997
    (10th Cir. 1993); see also United States v. Hatatley, 
    130 F.3d 1399
    , 1406 (10th
    Cir. 1997) (discussing aiding and abetting liability and differentiating it from
    principal liability). That being said, the government was required to prove Larry
    participated in the assault and battery of Tutt intending (or reasonably expecting)
    it would bring about his death. An unpredictable stabbing during the assault (and
    certainly not later) would not satisfy that requirement. No evidence was
    presented from which a rational jury could find Larry participated with the
    knowledge or reasonable expectation the assault would be fatal. Because aiding
    and abetting requires specific intent, United States v. Lambert, 
    995 F.2d 1006
    ,
    1008 (10th Cir. 1993), the act of assaulting Tutt, standing alone, is insufficient.
    At the very least, the government was required to show Larry knew or should
    have known a dangerous w eapon would be employed such that the jury could
    infer he appreciated the risk of mortal injury and participated in the assault
    nonetheless. But no such evidence, circumstantial or direct, was adduced.
    Consequently, there was insufficient evidence from which the jury could find
    Larry aided and abetted Tutt’s murder.
    -25-
    C.    Henry W oody
    Henry claims Hayes’s statements to A gent Hall regarding D efendants’
    propensity tow ard violence and talking about killing people when drinking were
    erroneously admitted. He argues Hayes’s statements were not relevant (Fed. R.
    Evid. 401), were unduly prejudicial (Fed. R. Evid. 403), and for the first time,
    almost as an afterthought, argues the statement is inadmissible as evidence of
    Henry’s character (Fed. R. Evid. 404(a)). Because the statements w ere originally
    intended to be introduced as substantive evidence, but actually came in as
    impeachment evidence, we separately address each context.
    1.     Statements as Substantive Evidence
    W hen the government attempted to introduce Hayes’s statements to Agent
    Hall as substantive evidence during Hayes’s direct examination, Henry objected
    on the basis of Rules 401 and 403. “A district court has broad discretion . . . and
    will be reversed only on a showing . . . . it [made] a clear error of judgment,
    exceed[ed] the bounds of permissible choice, or when its decision is arbitrary,
    capricious or whimsical, or results in a manifestly unreasonable judgment.”
    United States v. Nickl, 
    427 F.3d 1286
    , 1300 (10th Cir. 2005) (quotations and
    citation omitted).
    Rule 401 of the Federal Rules of Evidence defines relevant evidence as that
    which has “any tendency to make the existence of any fact that is of consequence
    to the determination of the action more probable or less probable than it would be
    -26-
    without the evidence.” Henry claims Hayes’s statements were irrelevant because
    (1) there was no foundation for Hayes’s knowledge of Henry’s conduct while
    drinking or angry, (2) there was no evidence the Defendants were angry the night
    of the murder, and (3) general threats directed at no one in particular are not
    probative of intent to kill a particular person. W e easily reject the Rule 401
    arguments.
    As to a lack of foundation, Hayes testified he knew Larry better than
    Henry, but that does not negate personal knowledge of Henry’s behavior. Hayes
    admitted he was interviewed by Agent Hall and clearly stated his acquaintance
    with both Defendants as w ell as his personal knowledge of Larry’s tendency to hit
    people w hen angry. Similarly, the lack of direct evidence that the Defendants
    were angry the night of the murder is not fatal. The jury could reasonably infer
    anger from their assault on M r. Tutt.
    The government concedes a defendant’s generic threats to people other than
    the victim are generally inadmissible to show the defendant was predisposed to
    murder the victim. See People v. W illiams, 
    407 N.E.2d 608
    , 613 (Ill. App. Ct.
    1980); see also Sikes v. State, 
    252 So.2d 258
    , 260-61 (Fla. Dist. App. Ct. 1971);
    State v. Faust, 
    118 S.E.2d 769
    , 772 (N.C. 1961). However, it argues the
    statements at issue were relevant because they prove motive for the
    unpremeditated murder of Tutt, stating: “In this case, the United States offered
    the evidence to show that the W oody brothers become violent and angry while
    -27-
    drinking. The evidence made it more probable that the W oody brothers attacked
    Tutt while drunk and angry, without any premeditation or any cognizable
    motive.” (Appellee’s Br. at 15.) Apparently, the government maintains if the
    jury believed Hayes’s statements to Hall about the Defendants’ violent behavior
    and threats of murder, it could infer the assault escalated into murder. Given this
    explanation, the court could reasonably conclude the evidence was relevant, a
    relatively low hurdle.
    Henry’s counsel also objected to the admission of the evidence with a very
    general objection under Rule 403. Relevant evidence is excluded under Rule 403
    if “its probative value is substantially outweighed by the danger of unfair
    prejudice, confusion of the issues, or misleading the jury, or by considerations of
    undue delay, waste of time, or needless presentation of cumulative evidence.”
    Fed. R . Evid. 403. “Unfair prejudice in the Rule 403 context ‘means an undue
    tendency to suggest decision on an improper basis, commonly, though not
    necessarily, an emotional one.’” See United States v. Tan, 
    254 F.3d 1204
    , 1211
    (10th Cir. 2001) (quoting Fed. R. Evid. 403 advisory committee’s note.)
    W e find the Seventh Circuit’s discussion of motive in the context of Rule
    404(b) instructive. In United States v. Cunningham, the court noted inadmissible
    character evidence (i.e., propensity) and evidence of motive can “overlap.” 
    103 F.3d 553
    , 556 (7th Cir. 1996). “They . . . overlap when the crime is motivated by
    a taste for engaging in that crime or a compulsion to engage in it (an ‘addiction’),
    -28-
    rather than by a desire for pecuniary gain or for some other advantage to which
    the crime is instrumental . . . .” 
    Id.
     The more “overlap” there is in a given case,
    the greater the danger a jury will misuse the evidence, even when given a limiting
    instruction. In Henry’s case, the overlap is complete.
    In opening argument, the government explained its theory of the case as
    follow s:
    This case is almost without a motive. It’s a fight. Kenneth Tutt got
    beaten. You say what was the motive? The motive you may infer
    from the evidence and the facts that you get, that M r. Tutt had
    recently got paid, he had money, and he having money would be able
    to supply, with that money, the alcohol that these two defendants and
    Kenneth were drinking. He was a source for the procurement of
    alcohol. And when he didn’t continue to procure it, he got beaten,
    punished, stabbed and killed.
    (R. Vol. VIII at 128.) Hayes’s statements regarding the Defendant’ propensity
    toward violence when drinking was the only evidence supporting this theory.
    There was testimony Tutt gave Larry some money to buy “ocean,” but no
    evidence Tutt had just been paid, no evidence Tutt and either Defendant argued
    over money, no evidence linking the murder to robbery, and no money found on
    Henry or Larry. Consequently, only the Defendants’ violent and threatening
    characters lend credence to the government’s theory of Tutt’s murder. As a
    result, the “motive” evidence is nothing more than evidence of Henry’s general
    propensity toward violence when drinking and angry. “Showing that a man is
    generally bad has never been under our system allow able. The defendant has a
    -29-
    right to be tried on the truth of the specific charge contained in the indictment.”
    United States v. Gilliland, 
    586 F.2d 1384
    , 1389 (10th Cir. 1978). W e conclude
    the district court erred in allow ing evidence of H enry’s violent character.
    The government argues that if there was error, it was harmless because no
    actual character “evidence” was adduced through Hayes’s continued denial he
    made the statement. The statements were presented to the jury solely through the
    government’s questions, which are not evidence, as the court so instructed. If this
    were the only introduction of Hayes’s statements, we might agree. However, the
    statements were reintroduced and affirmed by Hall only a short time later.
    2.     Statements as Impeachment Evidence
    Henry argues the district court improperly allowed the government to
    introduce inadmissible substantive evidence under the guise of impeachment.
    Although Henry did object to the use of the statement as improper impeachment,
    he did so only because he claimed Hayes’s testimony at trial was not inconsistent,
    an objection correctly overruled by the court. 6
    6
    Henry’s counsel objected to the admission of impeachment evidence
    under Rule 613 arguing that because Hayes testified he could not remember
    making the statements, the report was not inconsistent w ith Hayes’s testimony.
    The court overruled the objection stating:
    His testimony was quite mixed with “I don’t remember” or very
    affirmative “no’s” when he was very specifically asked, Did you say
    this, did you do this? . . . . And I think that there was a great deal or
    potential great deal of inconsistency in the statements as the w itness
    is going to relate them.
    -30-
    Rule 613(b) of the Federal Rules of Evidence provides:
    (b) Extrinsic evidence of prior inconsistent statement of w itness.
    Extrinsic evidence of a prior inconsistent statement by a witness is
    not admissible unless the witness is afforded an opportunity to
    explain or deny the same and the opposite party is afforded an
    opportunity to interrogate the witness thereon, or the interests of
    justice otherwise require. This provision does not apply to
    admissions of a party-opponent as defined in rule 801(d)(2).
    Rule 607 states: “The credibility of a witness may be attacked by any party,
    including the party calling the witness.” Read together, Rules 607 and 613(b)
    allow a party to impeach its own witness with extrinsic evidence of prior
    inconsistent statements. See United States v. Carter, 
    973 F.2d 1509
    , 1512 (10th
    Cir. 1992). Before such evidence is allowed, however, it must meet certain
    requirements. First, under Rule 613(b), the witness must be confronted with the
    statement and afforded an opportunity to explain or deny it. The record clearly
    demonstrates this requirement was met.
    There are further restrictions, however, to impeachment evidence. W hile
    not specifically incorporated in Rule 607 or Rule 613(b), when the contradiction
    (R. Vol. XI at 400.) Henry wisely does not raise this argument on appeal. See
    United States v. Rogers, 
    549 F.2d 490
    , 496 (8th Cir. 1976) (“A statement’s
    inconsistency may be determined from the circumstances and is not limited to
    cases in w hich diametrically opposite assertions have been made. Thus,
    inconsistencies may be found in changes in position; they may be implied through
    silence; and they may also be found in denial of recollection.”); United States v.
    Insana, 
    423 F.2d 1165
    , 1169-70 (2d Cir. 1970) (“The conclusion that prior
    testimony inconsistent with a present lack of memory may be admissible as a
    contradiction is not a novel one.”).
    -31-
    relates to a “collateral matter,” impeachment may be received only through the
    testimony of the witness to be impeached. United States v. Durham, 
    470 F.3d 727
    , 732 (8th Cir. 2006). Evidence extrinsic to that witness’s testimony is
    inadmissible to prove a witness’s trial testimony is contradicted by a previous
    statement. The application of the collateral matter rule is an extension of Rule
    403, which also remains controlling in admitting impeachment evidence. Id.; see
    also United States v. Buffalo, 
    358 F.3d 519
    , 524-25 (8th Cir. 2004).
    In addition, upon admission of prior inconsistent statements, “[i]t is well
    settled that contradictory statements introduced for the purpose of impeachment
    are not admissible as substantive evidence.” United States v. Neal, 
    452 F.2d 1085
    , 1086 (10th Cir. 1971); see also Carter, 
    973 F.2d at 1512
     (“A witness’ prior
    statements are admissible only to impeach or discredit the witness and are not
    competent substantive evidence of the facts to which the former statements
    relate.”) (quotations omitted). 7 Henry maintains Hayes’s
    7
    Henry also argues, although the evidence was not admissible for
    substantive purposes, the government’s primary purpose was to place the
    evidence before the jury for just that purpose. “Every circuit has said evidence
    that is inadmissible for substantive purposes may not be purposely introduced
    under the pretense of impeachment.” United States v. Peterman, 
    841 F.2d 1474
    ,
    1479 n.3 (10th Cir. 1988) (listing cases); see also Carter, 
    973 F.2d at 1512
     (“The
    government may not introduce evidence of prior statements under the guise of
    impeachment for the primary purpose of placing before the jury substantive
    evidence which is not otherwise admissible.”) (quotations omitted). A party may
    not call a witness knowing the witness will not provide substantive testimony but
    only to impeach the witness with damaging prior statements that would,
    otherwise, be inadmissible. However, the determination to admit or exclude
    -32-
    statements about the D efendants’ conduct when drinking fail each of these tests:
    impeachment evidence pivots on the intentions of counsel. See Peterman, 
    841 F.2d at 1480
     (factual findings by the trial court supported its conclusion the
    prosecutor did not call witness with the primary purpose of introducing evidence
    of his prior conviction.). In United States v. Clifton, the defendant challenged the
    admission of impeachment testimony that would have been inadmissible hearsay.
    
    406 F.3d 1173
     (10th Cir. 2005). In his concurrence, Judge Hartz observed:
    The Peterman rule strikes me as passing strange. W hy should the
    admissibility of evidence depend on the state of mind of the attorney
    proffering the evidence? To be sure, the prosecutor’s motive plays a
    limited role in some legal issues . . . But it is hard to find support in
    the Federal Rules of Evidence for considering attorney intent as a
    factor in determining admissibility. Instead, as one would expect, we
    look at factors relating to the probative and unfairly prejudicial
    impact of the evidence. Of course, the more such prejudicial impact
    exceeds the probative value, the greater the likelihood that the
    prosecutor’s motive in proffering the evidence was impure. But
    w hen the unfairly prejudicial impact substantially predominates, we
    should not admit the evidence just because the prosecutor's thoughts
    are pure, nor should we exclude evidence on the ground of
    prosecutorial obliquity when the probative value is not substantially
    outweighed by the danger of unfair prejudice. There is significant
    authority for my view. See United States v. Ince, 
    21 F.3d 576
    , 580
    (4th Cir. 1994) (“Federal evidence law does not ask the judge . . . to
    crawl inside the prosecutor’s head to divine his or her true
    motivation.”); United States v. Buffalo, 
    358 F.3d 519
     (8th Cir. 2004);
    4 Jack B. W einstein & M argaret A. Berger, Weinstein’s Federal
    Evidence § 607.02[2][b] (2d ed.2004); 27 Charles A lan W right &
    Victor James Gold, Federal Practice and Procedure: Evidence §
    6093 (1990) (recommending Rule 403 approach to propriety of
    admitting impeachment evidence, although suggesting that it may be
    useful to incorporate R ule 403 explicitly in Rule 607). I trust that we
    will have occasion to revisit this issue.
    Id., at 1185-86 (Hartz, J., concurring). W e agree, but need not reach the issue in
    this case because we can resolve the issue under a Rule 403 analysis.

    (1) Hayes’s statement concerned an irrelevant, collateral issue; (2) the evidence
    was highly prejudicial and its probative value regarding Hayes’s credibility was
    negligible; and (3) the statements were used as substantive evidence.
    a.     Collateral M atter
    The collateral matter rule is a subset of a court’s authority to exclude
    impeachment evidence under Rule 403. W alker, 930 F.2d at 791. “A matter has
    been held to be collateral if it could not have been introduced in evidence for any
    purpose independent of the impeachment.” Id.; see also United States v. Rosario
    Fuentes, 
    231 F.3d 700
    , 707 (10th Cir. 2000) (“Because the truth-seeking function
    of the court would be impaired, and because the questions [the witness] refused to
    answer were germane to issues in the indictment, the testimony was not
    collateral.”); Fryar v. Curtis, 
    485 F.3d 179
    , 184 (1st Cir. 2007) (“A matter is
    considered collateral if the matter itself is not relevant in the litigation to
    establish a fact of consequence, i.e., not relevant for a purpose other than mere
    contradiction of the in-court testimony of the witness. Stated another way,
    extrinsic evidence to disprove a fact testified to by a witness is admissible w hen it
    satisfies the Rule 403 balancing test and is not barred by any other rule of
    evidence.”). The danger of allowing impeachment via a collateral matter is that
    when the fact to be impeached is not material, “the trier of fact may become
    confused by the attention directed at an unimportant fact. As a result, the trier of
    fact may attach undue importance to extraneous matters.” 27 C HARLES A LAN
    -34-
    W RIGHT & V ICTOR J AMES G OLD , F EDERAL P RACTICE AND P ROCEDURE § 6096.
    In W alker, the defendant was charged with two counts of illegal possession
    of a firearm. One of the counts stemmed from an incident in which W alker drove
    to Hyle’s house, a man he suspected was dating his ex-wife. Hyle testified
    W alker shot at him and he returned fire. To impeach this testimony, W alker
    attempted to introduce evidence of the investigating officer’s testimony in a prior
    hearing that Hyle told the officer W alker did not shoot first. The trial court
    allowed W alker to put the officer on the stand. However, when the officer did not
    testify he was told Hyle shot first, the court precluded further questioning of the
    witness. W e upheld the trial court’s decision, reasoning:
    There is no dispute that the issue of w hether at some prior time M r.
    Hyle stated he had fired first was relevant only for impeachment
    purposes. The indictment charged only the status offense of
    possession of a weapon and did not include assault charges. W ho
    fired first was irrelevant to the issue of guilt. The defense effort to
    impeach M r. Hyle on the issue of who fired first was therefore a
    collateral issue . . . . [I]mpeachment on a collateral matter [is]
    properly excluded in the discretion of the trial court.
    930 F.2d at 791-92 (quotation omitted).
    “That evidence concerns a collateral matter does not, of course, necessarily
    render it inadmissible. To the contrary, such evidence is admissible provided that
    it is ‘relevant’ and not otherwise prescribed by law or rule.” United States v.
    Fonseca, 
    435 F.3d 369
    , 374-75 (D.C. Cir. 2006). Under Rule 401, evidence that
    contradicts a witness’s trial testimony, even on a collateral subject, may be
    -35-
    relevant “because it would undermine [his] credibility as a witness regarding facts
    of consequence.” 
    Id. at 375
    ; see also United States v. M arino, 
    277 F.3d 11
    , 24
    (1st Cir. 2002) (“Nevertheless, extrinsic evidence to disprove a fact testified to by
    a witness may be admissible if the trial judge deems that it satisfies the Rule 403
    balancing test and it is not excluded by another rule.”). Therefore, we proceed to
    review the admission of Hayes’s statements under a Rule 403 analysis.
    b.    Rule 403
    Rule 403 requires the court to balance the relative probative and prejudicial
    value of evidence. This “serves to prevent a party from calling a witness,
    knowing him or her to be adverse, merely to make an end-run around the rule
    against hearsay by impeaching the witness with a prior inconsistent statement that
    the jury would not otherwise have been allowed to hear.” Durham, 
    470 F.3d at 732
     (quotations omitted). The applicable inquiry is whether, under Rule 403,
    “[t]he prior statements are inculpatory to [the defendant] if considered to be true.”
    United States v. Logan, 
    121 F.3d 1172
    , 1175 (8th Cir. 1997). If so, “to be
    admissible, their value for impeachment purposes -- or portraying or exposing
    [the witness] as a person who is unworthy of belief -- has to outweigh the danger
    of unfair prejudice and jury confusion that those prior statements may create if
    admitted.” 
    Id.
     The value of impeachment, then, is determined after an
    examination of the entire testimony of the witness to be impeached.
    Hayes’s testimony established his age, 34; the location and lack of security
    -36-
    of his residence; his acquaintance with the Defendants; a birthday party on
    August 25, 2004; the presence of his father and his father’s companion on the
    25th in the shack; he did not see the Defendants on the 25th or 26th; he was
    interview ed by Agent Hall and another officer; Henry stutters when he gets
    nervous; 8 and Hayes did not remember or did not think he made certain
    statements to Agent Hall. In other words, he did not testify to much of anything
    demonstrating Henry’s guilt. Instead, any impeachment was most probative of
    what Hayes denied or could not remember at trial. Thus, the probative value of
    the impeachment, challenging his credibility to undermine the subject matter of
    his testimony, was negligible. M oreover, Hayes’s credibility was already
    attacked by the court when it admonished him during his direct examination.
    On the other hand, the admission of Henry’s alleged behavior when
    drinking or angry was highly prejudicial. No other w itness testified to H enry’s
    propensity for violence when drinking or his tendency to make death threats when
    angry. W e recognize “exclusion of evidence under Rule 403 that is otherwise
    admissible under the other rules ‘is an extraordinary remedy and should be used
    sparingly.’” Tan, 
    254 F.3d at 1211
     (quoting United States v. Rodriguez, 
    192 F.3d 946
    , 949 (10th Cir. 1999)). However, “the danger of confusion which arises from
    8
    Originally, Hayes stated he did not remember telling Hall that Henry
    stutters w hen Henry gets nervous. However, when asked directly if “H enry
    W ood, when he gets nervous, does he stutter?” Hayes answ ered “Yes.” (R. Vol.
    XI at 380.)
    -37-
    the introduction of testimony under circumstances such as are presented here is so
    great as to upset the balance and to warrant continuation of the rule of exclusion.”
    United States v. Ince, 
    21 F.3d 576
    , 580 (4th Cir. 1994) (quotations omitted).
    Thus, the unfair prejudice of Hayes’s out-of-court statement substantially
    outweighed the probative value and were inadmissible to impeach Hayes under
    Rule 403.
    c.    Substantive Use of Impeachment
    Because Hayes’s descriptions of the Defendants’ behavior was not admitted
    for its truth, the jury could not properly consider them evidence of H enry’s
    motivation to kill or of his guilt. United States v. M agleby, 
    241 F.3d 1306
    , 1313
    n.4 (10th Cir. 2001). Henry maintains, despite the court’s limiting instruction to
    the jury, this is exactly how the government urged the jury to use the information
    in reaching a verdict. W e must agree.
    In closing, the government stated, “In the course of the impeachment [of
    Hayes], later through Agent Hall, it was developed impeachment style on Hayes
    that he told Agent Hall when these two defendants get mad, they talk about
    killing people and [when] they drink, they threaten people. This is for you to
    decide because you’re the best people to do this.” (R. Vol. XII at 480.) In other
    words, the government invited the jury to use the impeachment testimony not to
    judge Hayes’s credibility, but to believe his statements to Hall and determine
    Defendants’ guilt from an inference they are violent characters who will murder
    -38-
    when drinking and angry.
    Indeed, the government continues to use the impeachment evidence for
    substantive purposes on appeal. In its harmless error argument, the government
    posits the evidence against Henry was sufficient, in part, because the evidence
    showed “Henry W oody told Paul Hayes not to say anything to the police about the
    murder.” (Appellee’s B r. at 26.) However, that “fact” w as introduced solely
    through the impeachment testimony of Agent Hall, and therefore cannot be
    considered as evidence of Henry’s guilt.
    W e sympathize with the district court given the lack of assistance from
    counsel for all parties in appropriately defining the evidentiary issues. However,
    despite our deferential review of the court’s evidentiary decisions, we conclude
    the admission of Hayes’s statement was error. The probative value was far
    outweighed by the danger of unfair prejudice and jury confusion. Given the facts
    before us, the admission of Hayes’s statements regarding Henry’s propensity
    toward violence “placed the underlying fairness of the entire trial in doubt.” See
    Rosario Fuentes, 
    231 F.3d at 708
    .
    As discussed in Larry’s appeal, the evidence supporting Henry and Larry’s
    guilt overlapped and, as a whole, w as w eak at best. In addition, the possibility
    the jury used these statements as substantive evidence cannot be ignored.
    The introduction of such testimony, even where limited to
    impeachment, necessarily increases the possibility that a defendant
    may be convicted on the basis of unsw orn evidence, for despite
    -39-
    proper instructions to the jury, it is often difficult for jurors to
    distinguish between impeachment and substantive evidence . . . .
    W hen the prosecution attempts to introduce a prior inconsistent
    statement to impeach its own witness, the statement’s likely
    prejudicial impact often substantially outweighs its probative value
    for impeachment purposes because the jury may ignore the judge’s
    limiting instructions and consider the "impeachment" testimony for
    substantive purposes.
    Ince, 
    21 F.3d at 580-81
     (quotations omitted); see also United States v. Beno, 
    324 F.2d 582
    , 587 (2d Cir. 1963) (“By attempting to show [the defendant] was the sort
    of man likely to be the perpetrator of crime, the prosecution denied him a fair
    opportunity to defend against the particular crime charged, for this sort of
    evidence weighs too heavily with the jury and makes impossible the dispassionate
    approach necessary if justice is to be achieved.”). Given the paucity of the
    government’s evidence (including the lack of forensic evidence against Henry),
    the small probative value of impeaching Hayes, the government’s suggestion in
    closing that the jury use the statements for substantive purposes (coupled with an
    unsupported comment that Hayes was afraid of the D efendants), we must
    conclude the admission of Henry’s propensity toward violence requires reversal
    -40-
    and a new trial. Therefore, the remainder of Henry’s claims are moot.
    Conclusion
    Because the government failed to present sufficient evidence to find Larry
    -41-
    W oody guilty beyond a reasonable doubt, his conviction is REVERSED. 9 The
    district court’s erroneous admission of evidence showing Henry W oody’s general
    propensity tow ard violent behavior placed the underlying fairness of the entire
    trial in doubt. His conviction is REVERSED and his case REM ANDED for
    further proceedings consistent with this order.
