The Honorable Yvette Kane, United States District Judge for the
Middle District of Pennsylvania, sitting by designation.
“We review the magistrate judge’s legal conclusions de novo and [his]
factual findings for clear error.” United States v. Powers, 129 F.4th 617, 623 (9th
Cir. 2025). We have jurisdiction under 28 U.S.C. § 1291, and we affirm.1
1. “For a challenge to the sufficiency of the evidence following a bench
trial, we review ‘whether, after viewing the evidence 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.’” United States v. Stackhouse, 105 F.4th
1193, 1198 (9th Cir. 2024) (quoting United States v. Laney, 881 F.3d 1100, 1106
(9th Cir. 2018)). For the evidence to be deemed sufficient in a case in which the
conviction depends in part on a defendant’s admission, the government (1) “must
introduce sufficient evidence to establish that the criminal conduct at the core of
the offense has occurred,” and (2) “must introduce independent evidence tending
to establish the trustworthiness of the admissions, unless the confession is, by
virtue of special circumstances, inherently reliable.”2 United States v. Lopez-
1
Mateo-Martinez’s Unopposed Motion to Extend Time to File Reply Brief,
Dkt. 30, is granted.
2
To the extent that an irreconcilable intra-circuit split exists as to the
standard of review that applies to the corroboration of an admission for purposes of
the corpus delicti doctrine, compare, e.g., United States v. Gonzalez-Godinez, 89
F.4th 1205, 1208 (9th Cir. 2024) (clear error); with United States v. Valdez-Novoa,
780 F.3d 906, 921 (9th Cir. 2015) (de novo), we need not call for rehearing en
banc because the outcome in this case does not turn on the applicable standard of
review, see Atonio v. Wards Cove Packing Co., Inc., 810 F.2d 1477, 1478 (9th Cir.
1987) (en banc). Even assuming de novo review applies, the government has
produced sufficient corroborating evidence.
2 24-257
Alvarez, 970 F.2d 583, 592 (9th Cir. 1992); see also Valdez-Novoa, 780 F.3d at
923 (the core conduct of a violation of § 1326(a) is “attempted illegal entry”).
These requirements are not “a high bar.” Gonzalez-Godinez, 89 F.4th at 1210.
The government need not provide “evidence that would be independently
sufficient to convict the defendant.” Id. (quoting Valdez-Novoa, 780 F.3d at 923).
The magistrate judge found that Mateo-Martinez was apprehended in a
remote area two miles north of the border and seven miles from the nearest port of
entry. A locked gate limits access to “the only road in and out of that area” to city
officials and the United States Border Patrol. After a remote imaging sensor was
triggered, a Border Patrol agent followed footprints leading away from the sensor
and found Mateo-Martinez “hiding” in a large bush with three other individuals.
Mateo-Martinez did not emerge from the bush until he was asked to do so. These
facts provide circumstantial evidence that Mateo-Martinez attempted to illegally
enter the United States and tend to establish the trustworthiness of his admission
that he is a Mexican citizen and lacked documents permitting him to be in the
United States. See Lopez-Alvarez, 970 F.2d at 592. Thus, there was sufficient
evidence to corroborate Mateo-Martinez’s admission of alienage.
2. The magistrate judge neither applied the incorrect legal standard for
specific intent nor improperly shifted the burden of proving intent to Mateo-
Martinez by finding that the fire in Mexico did not support a valid duress defense.
3 24-257
The Border Patrol agent testified that a “large fire” was burning somewhere across
the border and that he could see smoke from the fire when he arrested Mateo-
Martinez. The magistrate judge did not and was not required to infer from this
vague testimony that Mateo-Martinez had been in Mexico near the fire while it was
burning and then traveled into the United States to move away from the fire. See
United States v. Khatami, 280 F.3d 907, 910 (9th Cir. 2002). Without those
inferences, the fire was not relevant to Mateo-Martinez’s specific intent in entering
the United States.
Even if the fire provided an alternative explanation for Mateo-Martinez’s
conduct, absent evidence to the contrary, we presume the magistrate judge
considered this possibility and rejected it. See United States v. Stanton, 501 F.3d
1093, 1099 (9th Cir. 2007) (“[A] reviewing court faced with a record of historical
facts that supports conflicting inferences must presume—even if it does not
affirmatively appear in the record—that the trier of fact resolved any such conflicts
in favor of the prosecution, and must defer to that resolution.” (quoting Wright v.
West, 505 U.S. 277, 296–97 (1992))); see also United States v. Coutchavlis, 260
F.3d 1149, 1157 (9th Cir. 2001) (“That the magistrate judge did not orally explain
his reasoning with the precision that might be expected from a written decision is
not sufficient reason to conclude that he placed the burden on the defendant to
prove his innocence . . . .”). Moreover, the magistrate judge’s explanation of
4 24-257
which facts proved the “corpus” of the crime shows that he understood that
attempted illegal entry in violation of § 1325(a) requires the specific intent to enter
the United States “free from official restraint.” United States v. Rizo-Rizo, 16 F.4th
1292, 1295 n.1 (9th Cir. 2021).
3. Mateo-Martinez’s argument that § 1325 violates his Fifth Amendment
right to equal protection is foreclosed by United States v. Carrillo-Lopez, 68 F.4th
1133, 1154 (9th Cir. 2023).
AFFIRMED.
