Background

Humberto Yosvany Arriola-Rivero pleaded guilty in the Western District of Texas to two counts: conspiracy to transport illegally present aliens and conspiracy to harbor illegally present aliens, both under 8 U.S.C. § 1324. His advisory Guidelines range was 30 to 37 months’ imprisonment.

At sentencing, the district court found that Arriola-Rivero had sexually assaulted one of the women he was illegally harboring and transporting. Relying in part on that finding — supported by the victim’s statement, a witness statement, and a hospital discharge summary — and applying a U.S.S.G. § 2L1.1(b)(7) enhancement for serious bodily injury, the court imposed an upward variance sentence of 111 months. Arriola-Rivero appealed, arguing the variance was unreasonable, challenging the underlying factual finding, seeking a remand to expand the record with newly discovered DNA evidence he claimed was exculpatory, and contesting the district court’s denial of an evidentiary hearing.

The Court’s Holding

The Fifth Circuit affirmed on all grounds. The court declined to enlarge the record or hold the appeal in abeyance for the newly discovered DNA evidence, finding no basis to do so under its precedents. It also recharacterized Arriola-Rivero’s “substantive unreasonableness” argument — which rested on contesting the district court’s factual finding that the assault occurred — as a procedural challenge, and reviewed the underlying factual finding for clear error.

Applying the clear-error standard, the panel held that the district court’s finding was plausible in light of the record as a whole: the victim’s account, a corroborating witness, and the hospital discharge summary provided sufficient indicia of reliability, and Arriola-Rivero offered no rebuttal evidence at sentencing. The court likewise rejected his challenge to the § 2L1.1(b)(7) serious-bodily-injury enhancement. Finally, the court held that denial of an evidentiary hearing was not an abuse of discretion because Arriola-Rivero had a full opportunity to submit objections to the presentence report. As for the DNA report not presented below, the court noted that the proper vehicle to raise that claim is a collateral attack under 28 U.S.C. § 2255, not a direct appeal.

Key Takeaways

  • A sentencing challenge that disputes the district court’s underlying factual finding (e.g., whether a defendant committed an assault) is procedural in nature, not a substantive-reasonableness challenge, and is reviewed for clear error.
  • Sentencing courts may rely on victim statements, witness accounts, and medical records at sentencing without a formal evidentiary hearing, provided the evidence bears sufficient indicia of reliability and the defendant had an opportunity to respond through the PSR process.
  • Newly discovered evidence that was not presented to the district court cannot enlarge the appellate record on direct appeal; defendants must pursue such claims through a 28 U.S.C. § 2255 motion, subject to the one-year statute of limitations.
  • A substantial upward variance — here, roughly three times the top of the Guidelines range — can be sustained when grounded in serious uncharged criminal conduct supported by reliable evidence.

Why It Matters

This decision reinforces the high bar defendants face when challenging factual findings that drive upward variances. So long as the sentencing court’s findings are plausible and supported by reliable evidence — even evidence short of the trial standard — the Fifth Circuit will not disturb them. Defense counsel must ensure any rebuttal evidence, including forensic or scientific reports, is placed before the district court at sentencing rather than reserved for appeal.

The case also serves as a practical reminder that the direct-appeal record is frozen at what was before the district court. Defendants who later obtain potentially exculpatory evidence have one avenue for relief: a timely § 2255 motion. Attempting to expand the record or obtain a remand through the appellate court, absent extraordinary circumstances, will not succeed.
