This case arises from the kidnapping and murder of two children by members of the La Mara Salvatrucha gang, also known as “MS-13.” Appellants Ronald Herrera Contreras, Pablo Miguel Velasco Barrera, Henry Zelaya Martinez, Duglas Ramirez Ferrera, and Elmer Zelaya Martinez were each indicted on eight counts and they were tried together. The jury returned guilty verdicts on all counts for all of the Appellants following an eight-week trial. Appellants appeal their convictions. We affirm the guilty verdicts on all counts. We vacate the sentence of Henry Zelaya Martinez and remand for the sole purpose of his resentencing.
I. Background1
Appellants were members of MS-13, a violent transnational gang.2 MS-13 engages in crimes including: aggravated assault; robbery; homicide; extortion; and human, narcotics, and firearm trafficking. The gang has a complex hierarchical structure, including subdivisions called programs and even smaller local groups called “cliques.” 4 J.A. 1316.3
Two children (Victim 1 and Victim 2)5 were brutally murdered by Appellants in the summer of 2016. Appellants lured each of them to a remote park at night where they stabbed them to death. Victim 1 and Victim 2 knew one another. Victim 2 became a low-ranking affiliate of PVLS at just thirteen years old. Victim 2 had introduced Victim 1 to members of PVLS with the hope that he too would join. Like Victim 2, Victim 1 also became a low-ranking affiliate of PVLS. Victim 2 was just fourteen years old at the time he was murdered. Victim 1 was seventeen.
In August 2016, Victim 2 forwarded a photo of Victim 1 to several high-ranking PVLS leaders. On the basis of the photo, the PVLS leaders concluded that Victim 1 was affiliated with a rival gang. They immediately issued a “green light“—gang parlance for a death sentence—calling for Victim 1 to be murdered.
Several MS-13 members, including Elmer and Henry Zelaya, Ramirez Ferrera, and Herrera Contreras, devised a plot to carry out this directive. The MS-13 members told Victim 1 to come to the park by himself to attend an MS-13 meeting. Victim 1 complied and came to meet the members. Victim 1 walked with the MS-13 members to a secluded area in the park. Velasco Barrera remained behind to serve as a lookout. There, Victim 1
Sometime after murdering Victim 1, Ramirez Ferrera, Henry and Elmer Zelaya, and Herrera Contreras unlocked and examined Victim 1‘s cellphone. There they discovered that their ostensible reason for murdering Victim 1—that he had been a member of a rival gang—had been a mistake. On Victim 1‘s phone, they discovered a photo of him flashing an MS-13 hand sign. This indicated that Victim 1 had not, in fact, been associated with a rival gang. The group hid their discovery from the PVLS leadership. Because of their roles in the murder, Elmer and Henry Zelaya, Ramirez Ferrera, and Velasco Barrera all received promotions within the PVLS clique.6
Later that summer, rumors began to spread that Victim 2 was cooperating with law enforcement. Based on little more than guesses and gossip, PVLS leadership decreed that Victim 2 must be killed and approved a “green light” calling for his murder. In September, Elmer Zelaya, Herrera Contreras, and other MS-13 members picked up Victim 2 and drove him to the same park where they murdered Victim 1 the prior month. There, Appellants
Portions of Victim 2‘s murder were videoed by one of the Appellants on a cellphone. Victim 2‘s autopsy indicated that he had been stabbed so forcefully that his lower jaw was bisected, portions of his skull were fractured into 13 pieces, and his thigh bones and one of his shinbones were fractured. After the murder, Herrera Contreras regularly wore the shoes that had been taken from Victim 2‘s corpse. Once again, because of their role in the murder, Elmer Zelaya, Ramirez Ferrera, and Velasco Barrera received promotions within PVLS.7

A federal grand jury returned an eight-count indictment charging Appellants with the following counts:
- Count 1: Conspiracy to commit kidnapping and murder of Victim 1 in aid of racketeering activity, in violation of
18 U.S.C. § 1959(a)(5) ; - Count 2: Conspiracy to commit kidnapping and murder of Victim 2 in aid of racketeering activity, in violation of
18 U.S.C. § 1959(a)(5) ; - Count 3: Conspiracy to kidnap Victim 1, in violation of
18 U.S.C. § 1201(c) ; Count 4: Conspiracy to kidnap Victim 2, in violation of 18 U.S.C. § 1201(c) ;- Count 5: Murder of Victim 1 in aid of racketeering activity, in violation of
18 U.S.C. § 1959(a)(1) and(2) ; - Count 6: Murder of Victim 2 in aid of racketeering activity, in violation of
18 U.S.C. § 1959(a)(1) and(2) ; - Count 7: Kidnapping of Victim 1 resulting in death, in violation of
18 U.S.C. § 1201(a)(1) and(2) ; and - Count 8: Kidnapping of Victim 2 resulting in death, in violation of
18 U.S.C. § 1201(a)(1) and(2) .
Four of the eight counts, Counts 1, 2, 5 and 6, were charged under the Violent Crimes in Aid of Racketeering Activity statute, or VICAR.
Appellants pled not guilty and exercised their constitutional right to a jury trial. The trial lasted over eight weeks. Following the close of the Government‘s case, Appellants moved for judgments of acquittal under
Appellants raise numerous issues on appeal, some individual, some joint, and some collective. Having considered all of Appellants’ arguments, we now turn to our analysis.
II. Analysis
A. Evidentiary Challenges
Appellants raise a number of challenges to the admission of certain evidence during trial, which we discuss in turn below.
1. Expert Testimony
Over Appellants’ repeated objection, the district court qualified Ricardo Guzman, a Houston Police Department sergeant, as an expert witness and permitted him to testify about the history, rules and activities of MS-13. Appellants contend that the district court improperly qualified Guzman as an expert because he lacked the requisite experience with MS-13 in the Mid-Atlantic region. They also argue that Guzman‘s testimony improperly relied upon inadmissible hearsay. We address these arguments in turn.
A district court may admit the testimony of a “witness who is qualified as an expert by knowledge, skill, experience, [or] training” if (1) “the expert‘s . . . specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue“; (2) “the testimony is based on sufficient facts or data“; (3) “the testimony is the product of reliable principles and methods“; and (4) “the expert‘s opinion reflects a reliable application of the principles and methods to the facts of the case.”
Guzman testified regarding his extensive professional experience with MS-13 and, of particular relevance here, with MS-13 homicide investigations. He participated in approximately 25 MS-13 homicide investigations as both a sergeant and task force officer, five of which were in the “DMV” (the region that includes the District of Columbia, and its surrounding suburbs in Maryland and Virginia). Guzman had attended relevant professional trainings in the United States and Central America. At trial, Guzman testified specifically about becoming familiar with PVLS in Virginia through his investigative work. Accordingly, we conclude that the district court did not abuse its discretion in qualifying Guzman as an MS-13 expert.
Appellants’ argument that Guzman‘s testimony was improperly based on inadmissible hearsay in violation of the Confrontation Clause also fails. “To be admissible in federal court, evidence must satisfy both the Federal Rules of Evidence and the [U.S. Constitution‘s] Confrontation Clause.” United States v. Seward, 135 F.4th 161, 166 (4th Cir. 2025). Under
In Crawford v. Washington, the Supreme Court held that admitting testimonial hearsay by a nontestifying witness generally violates a defendant‘s Sixth Amendment Confrontation Clause rights unless the witness is unavailable to testify and the defendant had a prior opportunity to cross-examine the witness. 541 U.S. at 53–54. Thus, expert witnesses are barred from repeating testimonial hearsay as evidence. United States v. Mejia, 545 F.3d 179, 198–99 (2d Cir. 2008). Expert witnesses are not, however, precluded from “offering their independent judgments merely because those judgments were in some part informed by their exposure to otherwise inadmissible evidence.” United States v. Johnson, 587 F.3d 625, 635 (4th Cir. 2009). The proper question for a court, therefore, is “whether the expert is, in essence, giving an independent judgment or merely acting as a transmitter for testimonial hearsay.” United States v. Ayala, 601 F.3d 256, 275 (4th Cir. 2010) (quoting Johnson, 587 F.3d at 635).
Guzman‘s testimony did not run afoul of this rule. Far from serving as a “conduit or transmitter for testimonial hearsay,” Guzman gave “an independent judgment . . . applying his training and experience to the sources before him.” Johnson, 587 F.3d at 635. Guzman explained to the jury the history and structure of MS-13. His testimony was based on his extensive experience, knowledge, and personal observations, much of which was not
2. Historical Racketeering Evidence
Appellants next contend that the district court abused its discretion in admitting “historical racketeering evidence.” They argue that this evidence misled the jury and prejudiced Appellants in violation of
We see no extraordinary circumstances here. The Government‘s evidence about the three other murders had significant probative value particularly to the Government‘s case
Although the evidence was most certainly prejudicial—it established that Appellants, as members of MS-13, were members of an enterprise that carried out murders—it was not unduly so. The probative value of the evidence was not substantially outweighed by the risk of unfair prejudice. Udeozor, 515 F.3d at 264. Any prejudice was mitigated by defense counsel‘s opportunity to cross-examine the relevant witnesses. Counsel solicited testimony that their clients were not involved in the three other murders. The district court also instructed the jury that Appellants were “not on trial for any act or any conduct not specifically charged in the indictments,” 12 J.A. 5357, and we presume jurors follow the instructions of the district court. United States v. Camara, 908 F.3d 41, 49 (4th Cir. 2018) (quoting United States v. Olano, 507 U.S. 725, 740 (1993)). We therefore conclude that the district court did not abuse its discretion in admitting the Government‘s historical racketeering evidence.8
3. Video and Photo Evidence
Appellants maintain that the district court abused its discretion when it admitted certain disturbing and graphic videos and photos. Specifically, they challenge three categories of evidence: two videos of the murders, photos of the excavation of Victim 1 and Victim 2‘s graves, and autopsy photos.
Certain evidence and testimony presented at trial was undoubtedly gruesome. Perhaps the most disturbing of all were two videos recorded during Victim 2‘s murder. We agree with the Government, however, that the videos’ probative value was not outweighed by the risk of unfair prejudice. The videos placed several of the Appellants at the scene of the crime; corroborated witness testimony; helped establish the victims’ identities; and depicted parts of the events that were the subject of the charges.
While the Government could have relied on other video and photo evidence to meet its burden of proof,
Appellants point out that following the showing of one of the videos, the jury sent a note to the district court asking for a warning prior to the showing of graphic videos. Appellants maintain that this note is evidence of the jury‘s extreme emotional reaction to the videos. While the videos might have been disturbing to the jury, unfair prejudice requires a showing of “a genuine risk that the emotions of the jury will be excited to irrational behavior, and that this risk is disproportionate to the probative value of the offered evidence.” Udeozor, 515 F.3d at 264 (citation omitted). On our review of the record, we cannot say that the video evidence was so unfairly prejudicial that it risked causing the jury to act irrationally.
Appellants also object to the admission of 27 photographs of the sites where Appellants attempted to bury the victims’ remains. Although some jurors may have been shocked by what they saw, Appellants have failed to establish that any prejudicial effect of the photos’ admission substantially outweighed their probative value.
B. Jury Instruction Challenges
1. Duress Instruction
Appellants challenge the district court‘s refusal to instruct the jury on a duress defense. The crux of Henry Zelaya, Ramirez Ferrera, and Velasco Barrera‘s theory of defense was that they acted under duress because MS-13 members who fail to cooperate with gang orders would be punished with physical violence or even death.10 In support of this theory, Henry Zelaya and Ramirez Ferrera proposed a jury instruction on a coercion defense. Velasco Barrera‘s counsel referenced a duress instruction during his opening
This court reviews the district court‘s refusal to provide a requested jury instruction under the abuse of discretion standard. United States v. Cannady, 924 F.3d 94, 101 (4th Cir. 2019). To establish a duress defense, a defendant “must produce evidence which would allow the factfinder to conclude” that: he “was (1) under unlawful and present threat of death or serious bodily injury; (2) did not recklessly place himself in a situation where he would be forced to engage in criminal conduct; (3) had no reasonable legal alternative (to both the criminal act and the avoidance of the threatened harm);” and that there was “(4) a direct causal relationship between the criminal action and the avoidance of the threatened harm.” United States v. Crittendon, 883 F.2d 326, 330 (4th Cir. 1989).
Assuming without deciding that such a defense is even available for VICAR murder or VICAR conspiracy to commit murder, Appellants cannot establish that all four Crittendon factors are met. Our analysis begins and ends with the first Crittendon factor. “[G]eneralized fears will not support” the duress defense. Crittendon, 883 F.2d at 330. Instead, a defendant must show that a “real and specific threat existed at the time” of the defendant‘s illegal conduct. Id. No such evidence is reflected in the record. Consider, for example, United States v. Mooney, 497 F.3d 397 (4th Cir. 2007). There, the first Crittendon factor was satisfied where an individual held a gun to the defendant‘s forehead, requiring the defendant to take a gun from the individual, thereby forcing the defendant to possess a firearm unlawfully. Mooney, 497 F.3d at 406. Appellants, by contrast, intentionally and voluntarily went to the park for the sole purpose of participating in the murders. To be sure,
We need not reach the remaining Crittendon factors. We therefore hold that the district court did not abuse its discretion in declining to instruct the jury on duress.
2. Jury Instruction on a Lesser Included Offense
Henry Zelaya maintains that the district court abused its discretion when it declined to instruct the jury on whether aggravated assault with a deadly weapon was a lesser included offense of conspiracy to commit kidnapping and murder in aid of racketeering activity. The district court decided against giving a lesser included offense instruction, concluding that “the evidence in this case does not support a rational inference that Henry Zelaya Martinez merely assaulted the victims.” 12 J.A. 5337-38.
We review the denial of a proposed jury instruction under the abuse of discretion standard. E.g., Cannady, 924 F.3d at 101. Under
In this case, the asserted lesser included offense (aggravated assault with a deadly weapon) is not a subset of the greater offense (conspiracy to commit kidnapping and murder in aid of racketeering activity).11 See, e.g., Schmuck, 489 U.S. at 716–17; United States v. Walker, 75 F.3d 178, 180 (4th Cir. 1996). A few examples illustrate why this is the case. An individual can commit conspiracy to commit murder and kidnapping in aid of racketeering without committing aggravated assault with a deadly weapon. A defendant could also commit conspiracy to murder or kidnap an individual without using a deadly weapon.12 Further, a conspiracy is an agreement, while aggravated assault with a deadly weapon requires that the crime be completed. The differences between the statutory elements are sufficient to defeat Henry Zelaya‘s challenge. Therefore, the district court did not abuse its discretion in denying his request for a lesser included offense instruction.
C. Individual and Joint Challenges
We turn now to other challenges raised by Appellants individually and jointly.
1. Sufficiency of the Evidence
Velasco Barrera contends that there was insufficient evidence to find him guilty of Counts 5 and 6: murder of Victim 1 and Victim 2 in aid of racketeering activity. We also address a similar challenge to Counts 7 and 8: kidnapping Victim 1 and Victim 2 resulting in their deaths, seemingly joined by all Appellants. After the close of evidence, Velasco Barrera moved for judgment of acquittal on the basis that the Government failed to produce sufficient evidence and improperly relied on unreliable witnesses. See
We review de novo a district court‘s denial of a motion for acquittal. United States v. Freitekh, 114 F.4th 292, 308 (4th Cir. 2024). “A defendant challenging the sufficiency of the evidence bears a ‘heavy burden’ to overturn his conviction.” United States v. Hunt, 99 F.4th 161, 184 (4th Cir. 2024) (quoting United States v. Clarke, 843 F.3d 288, 297 (4th Cir. 2016)). This court must affirm the jury‘s verdict if, after drawing all reasonable inferences in the light most favorable to the prosecution, “any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.” Jackson v. Virginia, 443 U.S. 307, 319 (1979) (emphasis in original). We must refrain from making any credibility determinations. Rather, we “assume that the jury resolved all contradictions in testimony in favor of the [prosecution].” Freitekh, 114 F.4th at 308 (quoting United States v. Penniegraft, 641 F.3d 566, 572 (4th Cir. 2011)).
a. Counts 5 & 6: Murder in Aid of Racketeering Activity
In cases arising under VICAR, the prosecution must prove beyond a reasonable doubt that the defendant‘s “general purpose” in committing the alleged crime “was to maintain or increase his position in the enterprise.” United States v. Fiel, 35 F.3d 997, 1003 (4th Cir. 1994) (quoting United States v. Conception, 983 F.2d 369, 381 (2d Cir. 1992)). To establish that a defendant had the “requisite purpose,” the prosecution must present evidence “from which ‘the jury could reasonably infer that the defendant committed his violent crime because he knew it was expected of him by reason of membership in the enterprise or that he committed it in furtherance of that membership.‘” United States v. Zelaya, 908 F.3d 920, 931 (4th Cir. 2018) (Floyd, J., concurring) (quoting Fiel, 35 F.3d at 1004). A defendant may still be convicted under VICAR “even if maintaining or increasing his position in a racketeering enterprise is not his ‘only or primary concern’ in carrying out a violent crime.” Id. at 927 (quoting United States v. Tipton, 90 F.3d 861, 891 (4th Cir. 1996)).
The Government presented ample evidence at trial showing that one of Velasco Barrera‘s motives in carrying out the murders was to be promoted within the MS-13 hierarchy. Indeed, he was promoted after each one.
Appellants contend that they had not been promised promotions for participating in the murders, and question the veracity of certain witnesses’ testimony. Appellants point to the testimony of one witness who stated that none of the Appellants were promised a promotion for assaulting or murdering Victim 2. That same witness also testified, however, that MS-13 members are expected to commit violent acts, including murder, and
Appellants urge us to reverse their convictions because the Government relied on the testimony of cooperating witnesses. Appellants maintain that cooperating witnesses are categorically unreliable because they are willing to say whatever is necessary to further their own self-interests. Appellants’ argument would require us to evaluate the testimony of the Government‘s cooperating witnesses. Our role is not to assess the credibility of witnesses; indeed we are precluded from making credibility determinations. That is the constitutionally-enshrined province of the jury. The jury heard the witnesses’ testimony, listened to their cross-examinations, and observed their demeanor and body language. As the district court noted: the jurors are “the sole and exclusive judges of the credibility of each of the witnesses called to testify.” 12 J.A. 5360. We will not usurp their role.
Our standard of review requires us to view all evidence in favor of the Government, not against it. A rational jury could have found, beyond a reasonable doubt, that Velasco Barrera carried out the murders, at least in part, to increase his position in MS-13.
b. Counts 7 & 8: Kidnapping Resulting in Death
Counts 7 and 8, kidnapping resulting in the death of Victim 1 and Victim 2, required the Government to prove that Appellants inveigled the victims. See
A rational juror could find that Appellants inveigled Victim 1 and Victim 2. The evidence presented at trial was sufficient for a juror to find that gang members lured each victim to the park under the false pretense that a meeting would take place.
Appellants maintain that neither Victim 1 nor Victim 2 could have been inveigled because the victims were themselves affiliated, or indeed members, of MS-13. This assertion is without foundation. The VICAR statute contains no exception for gang members or affiliates who murder fellow members.
