MOLLY C. DWYER, CLERK
U.S. COURT OF APPEALS

v.
MEMORANDUM*
ERIC DAVID MARRUFO,
Defendant - Appellant.
Appeal from the United States District Court
for the District of Arizona
Cindy K. Jorgenson, District Judge, Presiding
Argued and Submitted February 4, 2025
Phoenix, Arizona
Before: HAWKINS, BYBEE, and BADE, Circuit Judges.
Eric Marrufo (“Marrufo”) appeals his convictions for five counts of
Aggravated Sexual Abuse of a Child under 18 U.S.C. §§ 2241(c), 2246(2), and 1153,
and one count of Abusive Sexual Contact of a Child under §§ 2244(a)(5), 2246(3),
and 1153, raising claims related to the admissibility of evidence. We have
jurisdiction under 28 U.S.C. § 1291, and we affirm.

This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
There was no error in the admission of Marrufo’s pretrial statements taken
while he was in custody on unrelated charges. That he was in custody necessitated
the Miranda warnings he was given, and any prefatory statements did not reasonably
alter their meaning. See United States v. Loucious, 847 F.3d 1146, 1149 (9th Cir.
2017) (“[T]he inquiry is simply whether the warnings reasonably convey to a suspect
his rights . . . .” (quoting Duckworth v. Eagan, 492 U.S. 195, 203 (1989))). Both his
responses to those warnings, and his testimony from his suppression hearing, clearly
show Marrufo understood the consequences of speaking with investigators.
Considering “the totality of all the surrounding circumstances” including “the
characteristics of the accused and the details of the interrogation,” Marrufo did not
provide an involuntary confession. United States v. Preston, 751 F.3d 1008, 1016
(9th Cir. 2014) (quoting Dickerson v. United States, 530 U.S. 428, 434 (2000)).
Marrufo fails to point to any evidence in the record tying the symptoms from his
2019 hospitalization to interrogations occurring two and four years earlier.
Nor did Tribal Detective Jacob Garcia’s testimony mentioning Marrufo’s
incarceration warrant a mistrial. See United States v. Allen, 425 F.3d 1231, 1236
(9th Cir. 2005). Marrufo’s trial counsel objected at sidebar and sought a mistrial.
Although the court denied counsel’s request, it offered a curative instruction which
counsel declined. Detective Garcia’s reference to Marrufo’s incarceration was
isolated and not repeated by the prosecution.
2 23-1606
Further, considering that Marrufo’s own testimony about his felony
convictions suggested his incarcerated status, there was no error in failing to issue a
limiting instruction sua sponte. See United States v. Voris, 964 F.3d 864, 875–76
(9th Cir. 2020). In sum, this isolated reference did not “materially affect[ ] the
verdict.” United States v. Yarbrough, 852 F.2d 1522, 1540 (9th Cir. 1988) (quoting
United States v. Guerrero, 756 F.2d 1342, 1347 (9th Cir. 1984)).
Nor was Detective Garcia’s single reference to Marrufo’s incarceration
“extraneous” within the meaning of Federal Rule of Evidence 606(b)(2)(a). See
Warger v. Shauers, 574 U.S. 40, 51 (2014) (“Generally speaking, information is
deemed ‘extraneous’ if it derives from a source ‘external’ to the jury.” (quoting
Tanner v. United States, 483 U.S. 107, 117 (1987))).
Neither did the district court abuse its discretion in declining to subpoena the
jurors regarding the impact of the statement. See Raley v. Ylst, 470 F.3d 792, 803
(9th Cir. 2006) (determining that the court could not inquire into the jury’s
deliberations in the absence of proof that the jury had been exposed to extrinsic
evidence).
Nor was there an abuse of discretion in certifying Shannon Martucci as an
expert. See United States v. Halamek, 5 F.4th 1081, 1088 (9th Cir. 2021)
(“Extensive experience interviewing victims can qualify a person to testify about the
relationships those victims tend to have with their abusers.”). Martucci had
3 23-1606
previously conducted over 1,700 interviews with victims of child abuse, and her
testimony described the possible modus operandi of adults who abuse children, but
did not describe the character traits of perpetrators. See United States v. Telles, 18
F.4th 290, 302–03 (9th Cir. 2021) (stating that “typical behaviors of sex offenders
of child victims” is admissible when it “illuminate[s] how seemingly innocent
conduct . . . could be part of a seduction technique” (quotations and citations
omitted)).
AFFIRMED.
