This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
Before: HURWITZ, and R. NELSON, Circuit Judges.**
Sylvia Olivas and Michael Salinas appeal convictions under the Racketeer
Influenced and Corrupt Organizations Act (RICO), 18 U.S.C. §§ 1961–1968,
stemming from their involvement in criminal activities of the Canta Ranas gang. We
have jurisdiction under 28 U.S.C. § 1291 and 18 U.S.C. § 3742(a). We affirm.
1. The district court erred by admitting expert testimony from Officer
Robert Rodriguez, Rene Enriquez, and Drug Enforcement Administration Agent
Steve Paris without making express reliability findings. See United States v.
Holguin, 51 F.4th 841, 855 (9th Cir. 2022). However, the error was harmless
because the record clearly demonstrates the reliability of these experts. See United
States v. Ruvalcaba-Garcia, 923 F.3d 1183, 1190 (9th Cir. 2019) (per curiam).
Reliability can be based on experience. See, e.g., United States v. Rodriguez,
971 F.3d 1005, 1018 (9th Cir. 2020) (experience reliably supported testimony about
gang “structure and operation”); United States v. Hankey, 203 F.3d 1160, 1169–70
(9th Cir. 2000) (“street intelligence” from investigations supported testimony about
gang “tenets” including “code of silence”). Similarly, “[o]fficers may testify about
their interpretations of ‘commonly used drug [or gang] jargon’ based solely on their
**

Ninth Circuit General Order 3.2(h).
2
training and experience.” United States v. Vera, 770 F.3d 1232, 1241 (9th Cir. 2014)
(quoting United States v. Bailey, 607 F.2d 237, 240 (9th Cir.1979)).
The record reveals that the experts had ample experience. Rodriguez served
as a patrol officer and member of the “Problem-Oriented Policing Team”
investigating drug and gang crimes for over a decade. He received over 100 hours
of gang-specific training, participated in “[w]ell over 100” criminal investigations,
including Canta Ranas, and had contacts with around 50 Canta Ranas members
specifically. Enriquez was inducted into the Mexican Mafia, held a position of
authority within it, and was familiar with the organization’s internal politics. Paris
participated in thousands of drug-related investigations related to street gangs,
conducted drug-related undercover work, and worked with several confidential
informants to investigate drug trafficking. The district court’s error in not making
express reliability findings was thus harmless.
2. The district court did not err in admitting dual-role testimony from
Officer Rodriquez and Enriquez. Although we “encourage” district courts to
“clearly separate” lay and expert testimony, Rodriguez, 971 F.3d at 1019, there is no
single prescribed method to do so. A district court may itself “clarify in the eyes of
the jury the demarcation between lay and expert testimony,” but “[t]hat distinction
can also be revealed through direct or cross examination.” United States v. Freeman,
3
498 F.3d 893, 904 (9th Cir. 2007). Here, the government repeatedly announced
before the jury when it shifted from “lay” to “expert” testimony.
The district court also did not plainly err by giving the Ninth Circuit’s model
dual-role testimony instruction, which the parties jointly proposed, at the conclusion
of trial rather than during testimony. We have found plain error only where no dual-
role instruction was given at all. United States v. Torralba-Mendia, 784 F.3d 652,
659 (9th Cir. 2015) (citing Vera, 770 F.3d at 1246). Even if it might be prudent to
provide a dual-role instruction during witness testimony, failure to do so is not plain
error. See Holguin, 51 F.4th at 863–64.
Enriquez’s previous involvement with the gang leader at the core of the RICO
conspiracy also did not warrant exclusion. Enriquez’s testimony was grounded in
his personal experiences and “rationally based on [his] perception.” Fed. R. Evid.
701(a). The record does not suggest any continued affiliation between Enriquez and
the Mafia during the alleged conspiratorial acts, the earliest of which occurred two
years after Enriquez left the Mafia.
Nor did the district court err in admitting Enriquez’s opinion that Olivas’s
actions suggested that she acted as a secretary for the gang. Expert witnesses are
“not permitted to offer a direct opinion on the defendant’s guilt or innocence,”
Freeman, 498 F.3d at 906, but Enriquez asserted no such thing, see United States v.
Fleishman, 684 F.2d 1329, 1335–36 (9th Cir. 1982) (expert may testify that
4
defendant was the “lookout” in a drug-trafficking operation). Nor was this testimony
“to a defendant’s actual mental state during the charged offense or testimony which
necessarily would imply that ultimate conclusion” in violation of Rule 704(b).
United States v. Morales, 108 F.3d 1031, 1038 (9th Cir. 1997). Enriquez’s testimony
merely “described a common practice of those who do have such intent.” Freeman,
498 F.3d at 906–07; see also United States v. Gomez-Norena, 908 F.2d 497, 502
(9th Cir. 1990) (finding no error in officer’s testimony that “large amounts of cocaine
[were] consistent with an intent to distribute” without offering “opinion of what
[defendant] actually thought”).
3. The district court did not err in permitting Case Agent Aaron Gutierrez
to testify. A law enforcement officer may testify about the meaning of ambiguous
recorded statements based on the officer’s “direct perception” of intercepted
communications coupled with “other facts he learned during the investigation.”
United States v. Gadson, 763 F.3d 1189, 1207 (9th Cir. 2014) (quoting Freeman,
498 F.3d at 904–05). “Such testimony is admissible even if the testifying officer
was not a participant in the recorded conversation.” Id. “A lay witness’s opinion
testimony necessarily draws on the witness’s own understanding, including a wealth
of personal information, experience, and education, that cannot be placed before the
jury.” Id. at 1208; see also Holguin, 51 F.4th at 865 (“We have allowed officers to
5
interpret communications based on the investigation as a whole and have not
required all information supporting lay opinion to be placed before the jury.”).
Gutierrez reviewed prison correspondence that he personally collected and
other materials he secured throughout his years-long investigation. The foundation
laid concerning Gutierrez’s investigation sufficiently supported his lay opinions.
See United States v. Barragan, 871 F.3d 689, 703–04 (9th Cir. 2017). This evidence
was also “rationally based on the witness’s perception” from his investigative
activity. Vera, 770 F.3d at 1242 (quoting Fed. R. Evid. 701).
4. Any error in the formulation of the instructions for the RICO conspiracy
was harmless. See Rodriguez, 971 F.3d at 1012 (“Jury instructions must be
evaluated ‘as a whole, and in context,’ rather than in piecemeal.” (quoting United
States v. Stapleton, 293 F.3d 1111, 1114 (9th Cir. 2002)). The instructions
adequately stated the mens rea necessary for conviction, requiring the jury to find an
agreement between two or more persons to conduct or to participate in the conduct
of the affairs of the enterprise through a pattern of racketeering activity, and that
appellants joined that conspiracy by willfully participating in it while knowing of its
object and intending to help further or facilitate the scheme. The instructions
therefore adequately captured the underlying offense and the role required of each
appellant. See Smith v. United States, 568 U.S. 106, 110 (2013) (“To convict a
defendant of narcotics or RICO conspiracy, the Government must prove beyond a
6
reasonable doubt that two or more people agreed to commit a crime covered by the
specific conspiracy statute (that a conspiracy existed) and that the defendant
knowingly and willfully participated in the agreement (that he was a member of the
conspiracy).”); Salinas v. United States, 522 U.S. 52, 65 (1997) (holding that
although “a conspirator must intend to further an endeavor which, if completed,
would satisfy all of the elements of [the underlying] criminal offense, . . . it suffices
that he adopt the goal of furthering or facilitating the criminal endeavor”).
5. Any error in the mens rea instruction for drug conspiracy redounded to
Salinas’s benefit and does not warrant reversal. See United States v. Collazo, 984
F.3d 1308, 1318–19 (9th Cir. 2021) (en banc); United States v. Irons, 31 F.4th 702,
717 (9th Cir. 2022) (similar instruction “provide[d] no grounds for reversal” because
“[a]t worst, the instruction required the Government to prove more than Collazo
required, but not less”).
6. The district court did not err in refusing Olivas’s proposed “willfully”
instruction for her money-laundering charge. Because the instructions noted that the
jury may not find guilt if it found Olivas did not think she was engaging with
unlawful activity, willfulness was adequately outlined. See Salinas, 522 U.S. at 65.
7. The district court did not err in its Guidelines calculation for Salinas by
adopting the Presentence Report’s (PSR) factually supported recommendations. See
Gadson, 763 F.3d at 1220. The PSR fully described Salinas’s involvement in the
7
conspiracies, including the type and amount of drugs he engaged with. Additionally,
the PSR adequately explained why Salinas was responsible for the entire amount of
drugs seized. The district court did not abuse its discretion by adopting it in
determining the sentence. See United States v. Gamez-Orduño, 235 F.3d 453, 464
(9th Cir. 2000).
8. Salinas’s lifetime term of supervised release was not substantively
unreasonable. Because the court adequately considered the 18 U.S.C. § 3553(a)
factors and explained its reasoning, its determination was not plainly erroneous. See
United States v. Rusnak, 981 F.3d 697, 711 (9th Cir. 2020) (affirming imposition of
a lifetime term of supervised release in part because district court had “fully
considered the 18 U.S.C. § 3553(a) factors”).
9. The district court did not erroneously admit statements about “La
Senora” under the co-conspirator hearsay exception. “Under Federal Rule of
Evidence 801(d)(2)(E), a statement of one coconspirator is admissible nonhearsay
against other coconspirators as an admission of a party-opponent, if the statement
was made during the course of and in furtherance of the common objectives of the
conspiracy.” United States v. Tamman, 782 F.3d 543, 553 (9th Cir. 2015).
8
The district court’s determination that these statements were made in
furtherance of the conspiracy is not clearly erroneous.1 United States v. Anderson,
56 F.4th 748, 755 (9th Cir. 2022) (per curiam). These statements fall under the
exception because they “further the common objectives of the conspiracy or set in
motion transactions that are an integral part of the conspiracy.” United States v.
Yarbrough, 852 F.2d 1522, 1535 (9th Cir. 1988). Statements made to “higher ups”
of the group may also be “in furtherance” of the conspiracy. See id. at 1536 (citing
United States v. Moody, 778 F.2d 1380, 1382 (9th Cir. 1985)).
AFFIRMED.
1
Nor were the statements unduly prejudicial, as they did not directly implicate
Olivas. See United States v. Williams, 423 F.2d 696, 696 (9th Cir. 1970) (per curiam)
(finding no error in admission of statements that did not implicate appellant).
