Defendant - Appellant. _________________________________
ORDER AND JUDGMENT* _________________________________
Before MATHESON, KELLY, and MORITZ, Circuit Judges. _________________________________
A jury convicted Anthony Armenta of several crimes stemming from a
shooting and physical altercation. He challenges his convictions on the basis that he
did not receive a fair trial or due process because the district court refused to sever
his trial from that of his codefendant. Although we agree with Armenta that he and
his codefendant presented mutually antagonistic defenses at least in part, Armenta
fails to demonstrate any prejudice flowing from that antagonism. And even if he
could show prejudice, he cannot establish that the district court abused its discretion
in issuing limiting instructions rather than severing his trial. So we conclude that the
* This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. But it may be cited for its persuasive value. See Fed. R. App. P. 32.1(a); 10th Cir. R. 32.1(A). Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 2
district court did not abuse its discretion in denying the motion to sever and affirm.
Background
Armenta’s convictions stem from an incident that took place on the banks of
the Mountain Fork River in May 2020 when a group of three friends returning from a
fishing trip encountered two strangers on the shore. That encounter would end with
shots fired and criminal charges filed against Armenta and his codefendant, Kevin
Ward.
According to trial testimony from victims Braydon Rich, Trent Short, and
Christopher Chappell, they had been fishing for a couple hours when they spotted a
storm rolling in and decided to head back to shore. As their boat neared the bank,
located on the Choctaw Nation Reservation, Rich exited the boat and walked up the
bank, intending to drive a vehicle down to the bank to pull the boat out of the river.
Armenta approached Rich and asked if he had jumper cables. When Rich replied in
the negative, Armenta pulled out a gun, pointed it at him, and told him not to move.
Rich ran to Chappell’s truck, jumped inside, and called 911. As Rich watched, a
second man, Ward, hit the truck’s windshield with a gun and yelled at him to get out.
While Rich took refuge in the truck, Short and Chappell remained in the boat.
Chappell heard Armenta tell Ward to “just pop him,” referring to Rich, and Ward
fired at the truck. R. vol. 4, 290. Armenta then started shooting at Chappell and
Short. Two bullets struck Short, but he and Chappell were able to swim to safety.
Armenta and Ward then pulled Rich out of the truck, and a fight ensued. Armenta
and Ward hit Rich multiple times, including with a tire tool, a gun, and a pipe. Rich
2 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 3
was eventually able to break away and run to a friend’s house.
Based on these events, the government indicted Armenta and Ward on four
counts: assault resulting in serious bodily injury in Indian Country (as to Short), two
counts of assault with a dangerous weapon with intent to do bodily harm in Indian
Country (as to Chappell and Rich), and one count of using, carrying, brandishing, and
discharging a firearm during and in relation to a crime of violence. The indictment
charged both men with each count both directly and on a theory of aiding and
abetting.
Armenta sought to sever the case against him from the case against Ward at
least six times. At the outset, in a pretrial motion, he cited statements Ward made to
investigators that implicated and placed blame on Armenta for firing at the boat,
asserting that those statements would be admissible against Ward in a joint trial but
would not be admissible in a separate trial against only Armenta. The district court
refused to sever, ruling that Armenta failed to show mutually antagonistic defenses or
a prejudicial risk to a specific trial right. The court noted that the government
intended to redact Armenta’s name from Ward’s confession and that the court would
provide a limiting instruction advising the jury to consider the confession only as
evidence of Ward’s guilt.
Armenta moved to sever a second time, after jury selection but before opening
statements, when it became clear that Ward might introduce evidence of Armenta’s
prior drug use as part of a duress defense. But the district court again denied the
motion, stating that judicial economy favored joinder and reiterating that the defenses
3 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 4
were not mutually exclusive and that no specific trial right was jeopardized.
Ward’s duress defense crystallized during trial. Ward testified that he smoked
marijuana and methamphetamine with Armenta on the day of the shooting and that
Armenta was “real paranoid” and “crazy.” Id. at 684. He explained that Armenta
believed a friend of his was in danger and that Armenta threatened to kill Ward and
Ward’s girlfriend if Ward did not stay in the car while Armenta drove around looking
for the friend. This threat seemed credible, Ward said, because Armenta’s girlfriend
had burn marks on her body, and Armenta implied that he inflicted them. Ward
testified that Armenta handed him a gun when they arrived at the river, then pointed
his own weapon at him and told him to shoot at Rich in the truck. He also said that he
received threatening letters from Armenta while in jail. To corroborate this
testimony, Ward called the lead detective on the case, who testified that he learned
Armenta had been awake for 20 days leading up to the shooting and had threatened to
blow up a bridge and kill people.1 He also called the mother of Armenta’s girlfriend,
who said she saw the burns on her daughter’s body.
Armenta not only objected to much of this testimony but also repeatedly
renewed his motion to sever, arguing that the government would not have been able
to bring in any of this evidence had he been tried alone. And because this evidence
was introduced by a codefendant and not the government, Armenta pointed out, he
1 The district court admitted the detective’s testimony for the limited purpose of corroborating Ward’s state of mind, not for its truth, and instructed the jury to that effect. 4 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 5
had not received notice pursuant to Federal Rule of Evidence 404(b) that evidence of
prior bad acts would be introduced. As a result, he contended, he was unable to
investigate the veracity of the allegations. But the district court consistently denied
Armenta’s motions, reiterating its view that the defenses were not mutually
antagonistic, that Armenta failed to point to a specific compromised trial right, and
that judicial economy favored proceeding jointly.2
Armenta’s defense theory, according to his opening statement, was that he
merely fired his gun in the air after hearing other shots fired, that Ward alone shot at
all three victims, and that although Armenta hit Rich with a gun during their physical
altercation by the truck, he did so only in self-defense. But Armenta rested without
calling any witnesses in support of this theory.3 And the government, for its part,
argued in closing that Ward and Armenta were “equally responsible” for each other’s
assaults on an aiding-and-abetting theory. Id. at 752.
The instructions to the jury included both an aiding-and-abetting instruction
2 The district court also denied Armenta’s two mistrial motions, which asserted undue prejudice from the detective’s testimony about Armenta’s drug use and mental state and from Ward’s testimony about the burns on Armenta’s girlfriend. The district court stated that “[t]he government could introduce all this in a separate trial” and that “Armenta’s problem in this case is the lack of evidence to support his theory of defense, not his misfortune of trial together with his co[]defendant.” R. vol. 4, 581, 747. 3 Instead, Armenta attempted to develop his theory through cross-examination. For example, Armenta elicited from Rich that Rich also hit Armenta, who never pointed a gun at him. He elicited from a detective that no bullets were recovered near the banks of the river and from a firearms examiner that ballistic testing was inconclusive. He also tried to impeach the victims’ perceptions of the incident, such as by suggesting that Chappell could not hear what Armenta said to Ward about shooting Rich. 5 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 6
for each count as well as an instruction that certain evidence was introduced for a
limited purpose. But the district court rejected Armenta’s request to specifically
instruct the jury that evidence of Ward’s state of mind could not be used against
Armenta. The jury convicted Armenta and Ward on all counts. The district court
sentenced Armenta to a total of 240 months in prison and three years of supervised
release.4
Armenta appeals.
Analysis
Armenta argues that the district court’s refusal to sever his trial from Ward’s
violated his rights to due process and a fair trial. We review the court’s refusal to
sever for abuse of discretion. United States v. Jones, 530 F.3d 1292, 1300 (10th Cir.
2008). Under this deferential standard of review, we will not reverse the district
court’s ruling “absent an affirmative showing of abuse of discretion and a strong
showing of prejudice.” Id. (quoting United States v. Stiger, 413 F.3d 1185, 1197
(10th Cir. 2005)); see also United States v. Swingler, 758 F.2d 477, 493 (10th Cir.
1985) (explaining that reversal is “rarely” warranted in this context).
Federal Rule of Criminal Procedure 8(b) allows for joinder of criminal
4 The district court sentenced Ward to 180 months in prison and three years of supervised release. In his appeal, which is currently pending before this court, Ward argues that he was arrested without probable cause and that the district court erroneously allowed the government and Armenta to cross-examine him about his post-arrest silence, wrongly excluded evidence corroborative of his duress defense, and erroneously instructed the jury on duress. Appellant’s Opening Brief at 24–27, United States v. Ward, No. 23-7088 (10th Cir. May 28, 2024). He additionally argues for cumulative error and challenges his sentence. Id. 6 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 7
defendants when “they are alleged to have participated in the same act or transaction
. . . constituting an offense or offenses.” And we generally “prefer district courts to
conduct joint trials of defendants who are charged together.” United States v.
Herrera, 51 F.4th 1226, 1264 (10th Cir. 2022). But “[a]n exception exists when a
party shows actual prejudice outweighing the expense and inconvenience of separate
trials.” Id.; see also Fed. R. Crim. P. 14(a) (allowing severance of defendants’ trials if
joinder “appears to prejudice a defendant”). Actual prejudice in this context requires
the defendant to “show the right to a fair trial is threatened or actually impaired.”
United States v. Thomas, 849 F.3d 906, 911–12 (10th Cir. 2017). It is not enough to
merely “point[] to a ‘negative spill[]over effect from damaging evidence presented
against codefendants.’” United States v. Caldwell, 560 F.3d 1214, 1221 (10th Cir.
2009) (quoting United States v. Wacker, 72 F.3d 1453, 1468 (10th Cir. 1995)).
In United States v. Pursley, we outlined a three-step framework for district
courts to use when deciding severance motions. 474 F.3d 757, 765 (10th Cir. 2007).
First, the court “must determine whether the defenses presented are ‘so antagonistic
that they are mutually exclusive.’” Id. (quoting United States v. Peveto, 881 F.2d
844, 857 (10th Cir. 1989)). “Second, because ‘[m]utually antagonistic defenses are
not prejudicial per se,’ a defendant must further show ‘a serious risk that a joint trial
would compromise a specific trial right . . . or prevent the jury from making a reliable
judgment about guilt or innocence.’” Id. (alteration and omission in original)
(quoting Zafiro v. United States, 506 U.S. 534, 539 (1993)). And third, if the first two
steps are satisfied, “the trial court exercises its discretion and ‘weigh[s] the prejudice
7 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 8
to a particular defendant caused by joinder against the obviously important
considerations of economy and expedition in judicial administration.’” Id. (alteration
in original) (quoting Peveto, 881 F.2d at 857). We consider each step in turn, keeping
in mind our overall deference to the district court’s ruling. See id.
I. Mutually Antagonistic Defenses
Mutual antagonism requires more than a “conflict of theories or one
defendant’s attempt to cast blame on another.” Peveto, 881 F.2d at 857. Rather, a
“defendant must demonstrate that the acceptance of one party’s defense would tend
to preclude the acquittal of the other[] or that the guilt of one defendant tends to
establish the innocence of the other.” Id. Thus, we have explained that to find mutual
antagonism, “[t]he essence or core of the defenses must be in conflict such that the
jury, in order to believe the core of one defense, must necessarily disbelieve the core
of the other.” Swingler, 758 F.2d at 495 (quoting United States v. Romanello, 726
F.2d 173, 177 (5th Cir. 1984)); see also United States v. Dirden, 38 F.3d 1131, 1141
(10th Cir. 1994) (“The defenses truly must be mutually exclusive, such that the jury
could not believe the core of one defense without discounting entirely the core of the
other.”).
Examples from caselaw illustrate the logical puzzles involved in this analysis.
In Peveto, two codefendants were charged with violating and conspiring to violate
drug laws based in part on their presence at a house containing various drug
paraphernalia. 881 F.2d at 848. At trial, one defendant asserted that he was present at
the house only because he was becoming an informant and attempting to “set up”
8 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 9
drug dealers. Id. at 849. To prove this theory, the defendant testified that his
codefendant was one such drug dealer—and this was “the only evidence at trial of
any criminal behavior on [the codefendant’s] part.” Id. at 857. The codefendant,
meanwhile, maintained that he was innocent and at the house only because he was
afraid of the defendant, who would not let him leave. Id. at 857. We pointed out that
both things could not be true at the same time: either the defendant was an informant
and the codefendant was a drug dealer, or the defendant was not an informant and the
codefendant was an innocent bystander held against his will. Id. at 857–58. We
therefore concluded that these defenses were so antagonistic as to be mutually
exclusive. Id. at 858.
Similarly, in Pursley, we found mutual antagonism where one defendant
claimed he did not assist in preparation of fraudulent tax returns and did not work at
the company listed on them, while his codefendant said the opposite. 474 F.3d at 765.
The defendant argued “no crime was committed by him,” while his codefendant
“maintained no crime was committed at all.” Id. “A jury could not simultaneously
believe” the two theories of defense. Id. at 766.
In contrast, we have found no mutual antagonism where a jury could conclude
both defense theories were true. In Swingler, for example, one defendant generally
disclaimed involvement in conspiracies to manufacture and distribute amphetamines,
while a codefendant argued that he was involved, but only under duress from
members of a violent gang. 758 F.2d at 494. Because the men were arrested together,
the defendant argued that to find his codefendant was acting under duress, a jury
9 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 10
would have to conclude that the defendant threatened his codefendant and was guilty.
Id. at 494, 496. But we held that a jury could conclude the defendant was not
involved and the codefendant was under duress from another member of the gang. Id.
at 496. Thus, neither defense “contained the sort of direct accusation that would have
logically prevented the jury from accepting both theories.” Id.
We arrived at a similar outcome in Dirden. There, the defendant, his
codefendant, and a third person were arrested in a car where police found drugs and a
gun. 38 F.3d at 1135, 1141. Both the defendant and his codefendant claimed that the
contraband did not belong to them. Id. These defenses were not mutually
antagonistic, we held, because a jury accepting the codefendant’s defense “would not
be compelled to reject [the defendant’s] defense that the drugs and firearm were not
his,” particularly given that there were three people in the car. Id. at 1141. The ability
to accept multiple theories of defense was also a deciding factor in United States v.
Linn, 31 F.3d 987 (10th Cir. 1994). After an arson, the defendants accused each other
of starting the fire, but they also presented theories at trial that it was accidental or
that an unknown arsonist was involved. Id. at 989, 992. We held that “[t]he jury
could have believed all of [d]efendants’ theories and acquitted all of them, but,
unfortunately for [d]efendants, did not.” Id. at 992.
Turning to the case before us, we note as an initial matter that it is difficult to
determine the exact contours of Armenta’s defense because his theory was presented
only in opening and closing arguments, with no independent evidence to support it.
But recall that based on his opening argument, Armenta’s defense as to Rich was that
10 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 11
he heard shots fired, so he fired his gun into the air, and that during the physical
altercation with Rich, he hit him with a gun in self-defense. And recall that Ward’s
defense as to Rich was that Armenta pointed a gun at Ward and told him to shoot at
Rich, which he did under duress based on fear created by Armenta’s prior threats and
alleged abuse of his girlfriend. Ward also denied pulling Rich out of the car and
attacking him with Armenta.5 As to the other two victims, Chappell and Short,
Armenta said Ward shot at them. But Ward said Armenta was the one who shot at
them. We consider mutual antagonism of these defenses first as to Rich and then as
to Chappell and Short.
Finding Ward not guilty of the assault on Rich based on duress would require
finding Armenta guilty of that assault on an aiding-and-abetting theory.6 That is
5 Another complicating factor as to Rich is that both defendants could have been convicted of assaulting him based on different acts. In its closing argument, the government said Armenta pointed a gun at Rich, told Ward to shoot Rich, and then hit Rich with a gun. The government argued Ward shot at Rich and joined Armenta in attacking Rich with a pipe or pistol. 6 The government contends Ward’s duress defense stemmed not from Armenta’s guilt of the charged offenses but from Armenta’s earlier alleged threats and physical abuse. And at oral argument, the government suggested that a jury could accept the following:
Armenta could believe he was under attack, bullets are flying, he needs to tell his friend, ‘Shoot the truck; shoot the truck.’ He says ‘shoot the truck’ in self-defense because he believes bullets are being fired around. Ward, at the same time, his belief based on everything he saw, is that he had no choice.
Oral Argument at 23:14–23:31. Although a jury could theoretically believe those two theories, those are not the defenses that were presented at trial. Armenta never claimed that he told Ward to shoot based on self-defense. Rather, through cross- examination, he implied that one of the victims misheard him. Further, Ward’s duress 11 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 12
because to accept Ward’s duress defense, a jury would necessarily believe that
Armenta pointed a gun at Ward and told him to shoot Rich. Therefore, belief in
Ward’s defense “would tend to preclude the acquittal” of Armenta. Peveto, 881 F.2d
at 857. However, the reverse is not necessarily true: finding Ward guilty of the
assault on Rich would not “tend[] to establish the innocence” of Armenta. Peveto,
881 F.2d at 857. Rather, Armenta could still be guilty of assault based on pointing
the gun at Rich or later hitting him with the gun. Similarly, finding Armenta guilty of
assaulting Rich would not establish Ward’s innocence. For instance, if Armenta was
guilty of assault for initially pointing the gun at Rich, then Ward could still be guilty
of assault for shooting at Rich (or for hitting Rich with a tire iron and pipe).
Therefore, as to Rich, Armenta’s and Ward’s defenses were not entirely mutually
antagonistic.
In contrast, Armenta’s and Ward’s defenses for the assaults on the two men in
the boat—Chappell and Short—appear to be fully mutually antagonistic. Armenta
said that Ward shot at these victims, while Ward said that Armenta shot at them. This
is exactly the kind of “direct accusation that would have logically prevented the jury
from accepting both theories.” Swingler, 758 F.2d at 496. Either Armenta fired at the
victims or Ward did, just as the defendant in Peveto either was an informant or not,
and the defendant in Pursley either worked for the company identified on the tax
defense depended not only on Armenta’s prior bad acts, but also on Armenta pointing a gun at him at the moment Ward shot at the truck.
12 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 13
return or did not. See Peveto, 881 F.2d at 858; Pursley, 474 F.3d at 765–66.
In sum, the defenses as to Rich appear to be only partially mutually
antagonistic, but the defenses as to Chappell and Short appear to be fully mutually
antagonistic. We therefore turn to the next Pursley prong.
II. Risk of Compromising Trial
“Mutually antagonistic defenses are not prejudicial per se.” Zafiro, 506 U.S. at
539. Accordingly, to establish prejudice under the second step of Pursley, a
defendant must demonstrate “a serious risk that a joint trial would compromise a
specific trial right . . . or prevent the jury from making a reliable judgment about guilt
or innocence.” 474 F.3d at 765 (omission in original) (quoting Zafiro, 506 U.S. at
539). Severance is not warranted “merely because [defendants] may have a better
chance of acquittal in separate trials.” Zafiro, 506 U.S. at 540. But the risk of
prejudice may be present where “evidence that the jury should not consider against a
defendant and that would not be admissible if a defendant were tried alone is
admitted against a codefendant.” Id. at 539. This risk is “increased when many
defendants are tried together ‘in a complex case and they have markedly different
degrees of culpability.’” United States v. Sarracino, 340 F.3d 1148, 1165 (10th Cir.
2003) (quoting Zafiro, 506 U.S. at 539).
That said, we have held a defendant cannot make the requisite showing of
prejudice just because evidence tied to a codefendant’s defense has a “spillover”
effect on him. United States v. Zapata, 546 F.3d 1179, 1191–92 (10th Cir. 2008).
“Rather, a defendant must show that he was deprived of his right to a fair trial.” Id. at
13 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 14
1191. So in Zapata, we held that the defendant failed to show prejudice from
spillover evidence where the trial also included “clear and direct testimony at trial
that specifically implicated [him] in the conspiracy.” Id. at 1192. Relatedly, we have
found no prejudice where spillover evidence does not directly relate to elements of
the charged crime. See Jones, 530 F.3d at 1303. In Jones, two defendants were
charged with bank fraud and conspiracy, and when one was arrested, she was found
with marijuana and a gun, resulting in further charges against her. Id. at 1295–96. At
trial, she elicited testimony about her codefendant’s drug dealing to suggest that the
marijuana belonged to him. Id. at 1302–03. Her codefendant argued that this
evidence had a spillover effect, confusing the jury and “creating an unfavorable
impression of him with jurors.” Id. at 1301. But this court found no prejudice because
no specific trial right was implicated, and the evidence of the codefendant’s drug
dealing did not help the government prove the elements of bank fraud and
conspiracy. Id. at 1303.
Seeking to establish prejudice here, Armenta broadly argues that Ward’s
duress defense risked compromising his right to confront the witnesses against him
and to receive due process and a fair trial. We do not agree. Although Armenta
argues that Ward’s testimony in support of his duress defense placed Armenta at the
scene, implicated him in the attack of Rich, proved that Armenta fired a gun, and
implied that Armenta shot at the boat, Armenta himself admitted to being at the
scene, attacking Rich (albeit in self-defense), and firing his gun (albeit at the sky).
Moreover, even without Ward’s testimony, the victims’ “clear and direct
14 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 15
testimony at trial” expressly implicated Armenta. Zapata, 546 F.3d at 1192. In
particular, the two men in the boat testified that Armenta shot at them, while Rich
testified that Armenta pointed a gun at him and attacked him. This evidence would
have been admitted had Armenta been tried separately, and Armenta did not
meaningfully attempt to refute it. He presented no evidence in support of his theory
that he shot into the air and that he only hit Rich in self-defense. These facts are
reminiscent of Pursley, where we found mutually antagonistic defenses but no
prejudice because the defendant failed to present any evidence supporting his defense
theory. See 474 F.3d at 766. Armenta’s problem was “the lack of evidence to support
his theory of defense, not his misfortune of” being tried jointly with Ward. Id.
Armenta also argues that prejudice exists because Ward introduced
inflammatory character evidence related to his drug use, prior threats, and the burns
he allegedly inflicted on his girlfriend that could not have been admitted in a separate
trial against him alone. He further emphasizes that because Ward was not a
prosecutor required to provide notice before presenting prior-bad-acts evidence,
Armenta was unprepared to rebut it. At the outset, we do not agree that none of this
evidence would have come in if Armenta was granted a separate trial. For instance,
as the government points out, it could have sought to introduce Armenta’s alleged
drug use on the day of the assaults and his comments about harming others to
establish his motive or intent. See Fed. R. Evid. 404(b)(2). But we need not decide
whether this evidence would have been admitted in a separate trial to conclude that
Armenta was not prejudiced by it. The spillover of evidence from Ward’s defense
15 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 16
was primarily related to Armenta’s prior drug use and threats, not the elements of the
charged offenses. See Jones, 530 F.3d at 1303. Thus, Ward’s duress evidence did not
help the government prove its case against Armenta; the victims carried that burden.
Under these circumstances, the jury was perfectly capable of reaching a reliable
determination of innocence or guilt, and Armenta fails to show prejudice under the
second step of Pursley.
III. Weighing Prejudice Against Judicial Economy
Armenta’s failure to establish prejudice is sufficient to affirm the district
court’s denial of severance. See Jones, 530 F.3d at 1300. But we nevertheless briefly
address the third step of Pursley, under which a district court “weigh[s] the prejudice
to a particular defendant caused by joinder against the obviously important
considerations of economy and expedition in judicial administration.” 474 F.3d at
765 (alteration in original) (quoting Peveto, 881 F.2d at 857). Even if a defendant can
demonstrate prejudice, this step of the analysis “leave[s] the tailoring of any relief to
the trial court’s discretion.” United States v. Hill, 786 F.3d 1254, 1273 (10th Cir.
2015). For example, the Supreme Court has recognized that “limiting instructions[]
often will suffice to cure any risk of prejudice.” Zafiro, 506 U.S. at 539; see also
United States v. Small, 423 F.3d 1164, 1182 (10th Cir. 2005) (noting that Supreme
Court “has sanctioned” limiting instructions “as an alternative to the more drastic
remedy of severance”).
Here, assuming Armenta established prejudice of some kind, the other side of
the balance nevertheless weighed strongly in favor of joinder. When the district court
16 Appellate Case: 23-7035 Document: 94-1 Date Filed: 11/14/2024 Page: 17
denied Armenta’s motions to sever during the trial, it cited efficiency and economy
as reasons to proceed together. And that justification makes sense: both defendants
were charged with the same assaults, including under a theory of aiding and abetting,
resulting in substantial overlap between the witnesses and exhibits. See United States
v. Hall, 473 F.3d 1295, 1302 (10th Cir. 2007) (recognizing “that a joint trial was in
the interests of judicial economy because the exact same witnesses and exhibits”
would be used in both trials). Moreover, given this strong interest in judicial
economy, the district court was well within its discretion to cure any prejudice to
Armenta by way of limiting instructions rather than severance.7 See Zafiro, 506 U.S.
at 539.
