MOLLY C. DWYER, CLERK
U.S. COURT OF APPEALS
FOR THE NINTH CIRCUIT
UNITED STATES OF AMERICA, No. 23-3775
D.C. No.
Plaintiff - Appellee, 3:20-mj-20306-AHG-WQH-1
v.
MEMORANDUM*
J. INES RUIZ-RIVERA,
Defendant - Appellant.
Appeal from the United States District Court
for the Southern District of California
William Q. Hayes, District Judge, Presiding
Argued and Submitted February 4, 2025
Pasadena, California
Before: MILLER, LEE, and DESAI, Circuit Judges.
J. Ines Ruiz-Rivera appeals his misdemeanor conviction for attempted illegal
entry into the United States, in violation of 8 U.S.C. § 1325. He argues that the
magistrate judge erred in denying his motion to suppress his post-arrest confession.
We have jurisdiction under 28 U.S.C. § 1291, and we affirm.
On appeal from a district court’s order affirming a misdemeanor conviction,

we review the magistrate judge’s decision directly, giving no deference to the
district court. See United States v. Stanton, 501 F.3d 1093, 1099–1101 (9th Cir.
2007). “We review the adequacy of Miranda warnings de novo.” United States v.
Gonzalez-Godinez, 89 F.4th 1205, 1208 (9th Cir. 2024). We review for clear error
a finding that a defendant’s waiver of his Miranda rights was knowing and
intelligent. Collazo v. Estelle, 940 F.2d 411, 416 (9th Cir. 1991) (en banc).
We assume, without deciding, that Ruiz-Rivera’s post-arrest interrogation
violated Miranda v. Arizona because Ruiz-Rivera did not knowingly and
intelligently waive his rights. 384 U.S. 436 (1966); see United States v. Crews, 502
F.3d 1130, 1140 (9th Cir. 2007). Any error was harmless because even without the
statements made in that interrogation, “the evidence of guilt was overwhelming.”
United States v. Butler, 249 F.3d 1094, 1101 (9th Cir. 2001).
The border patrol agent who arrested Ruiz-Rivera testified that he found
Ruiz-Rivera laying down next to a shed at night. Ruiz-Rivera was 200 yards north
of the border and 25 miles from the nearest port of entry. He was wearing
“booties,” which the agent testified are worn to “disguise [the wearer’s] footprints
from pursuing border patrol agents.” Before his arrest, Ruiz-Rivera told the agent
that he was a Mexican citizen who was in the United States unlawfully. Because
Ruiz-Rivera’s pre-arrest statements and the circumstances of his arrest provided
overwhelming evidence of guilt, any error in admitting his post-arrest statements

was harmless.
AFFIRMED.
