Attempted Evasion + Unknown Community Ties Can Sustain Pretrial Detention for Flight Risk Under § 3142(g) (Even Amid Alleged Burden-Shifting)

1. Introduction

In United States v. Perez-Perez (5th Cir. May 27, 2026) (per curiam) (unpublished), the Fifth Circuit affirmed a district court order denying Maximiliano Perez-Perez’s request to revoke a magistrate judge’s pretrial detention order. Perez-Perez faced a charge of assaulting a federal officer under 18 U.S.C. § 111, arising out of an encounter where he allegedly resisted, fled, and bit an officer during arrest.

The central appellate issues were (1) whether the district court erred in concluding that no conditions of release could reasonably assure Perez-Perez’s appearance at trial (i.e., that he posed a substantial risk of flight), and (2) whether the district court impermissibly shifted the burden to Perez-Perez to prove he would not flee, instead of requiring the Government to prove flight risk.

2. Summary of the Opinion

The Fifth Circuit held that the record as a whole supported pretrial detention. It emphasized evidence that Perez-Perez attempted to evade arrest (fled on foot, struggled, and bit an officer), lacked identification, had unknown residence and employment, and admitted unauthorized presence in the United States for about three years without any linked criminal or immigration record.

Even assuming arguendo that certain language in the district court’s order could be read as burden-shifting, the Fifth Circuit concluded that the evidentiary record still supported detention under the deferential appellate standard. The court also rejected arguments that the Government conceded inability to meet its burden and found no indication that the district court relied on an immigration detainer or potential deportation.

3. Analysis

A. Precedents Cited

1) Appellate review framework for detention orders

  • United States v. Esquivel-Bataz, 155 F.4th 491 (5th Cir. 2025): Used to restate the limited scope of appellate review and the statutory four-factor framework under 18 U.S.C. § 3142(g). The panel also invoked Esquivel-Bataz by comparison when addressing (and distinguishing) claims involving immigration detainers.
  • United States v. Fortna, 769 F.2d 243 (5th Cir. 1985): Quoted via Esquivel-Bataz for the proposition that appellate review of detention determinations is limited.
  • United States v. Rueben, 974 F.2d 580 (5th Cir. 1992): Provided two key rules: (i) the district court must conduct a de novo review of the magistrate judge’s detention decision and make an independent determination, and (ii) on appeal, the question is whether “the evidence as a whole supports the conclusions” below. Rueben also supplied the “ties to locality” language later echoed through Patel.
  • United States v. Hare, 873 F.2d 796 (5th Cir. 1989): Quoted via Rueben for the deferential standard: absent legal error, a detention order should be upheld if supported by the proceedings below.

2) Evasion of arrest as probative of flight risk

  • United States v. Sims, 801 F. App’x 324 (5th Cir. 2020) (per curiam): Cited to support that an attempt to evade police at arrest may be considered among factors justifying detention.
  • United States v. Wright, 697 F. App’x 297 (5th Cir. 2017) (per curiam): Cited for the same general principle, specifically noting “apparent attempts to evade arrest” as supporting a finding of flight risk by a preponderance of the evidence.
  • United States v. Cruz-Reyes, 229 F.3d 1134 (1st Cir. 2000) (Table): Used as out-of-circuit persuasive support that past flight can justify discounting self-surrender or other assurances and may support detention.

3) Community ties and burden of proof

  • United States v. Patel, 685 F. App’x 323 (5th Cir. 2017): Quoted for the proposition that “longstanding ties to locality” are a relevant risk factor when evaluating appearance at trial.
  • United States v. Trosper, 809 F.2d 1107 (5th Cir. 1987): Cited for the burden rule: the Government must establish by a preponderance of the evidence that no set of conditions can reasonably assure the defendant’s appearance. Perez-Perez relied on Trosper to argue improper burden-shifting.

B. Legal Reasoning

The court’s reasoning follows the Bail Reform Act’s structure, focusing primarily on the § 3142(g) “history and characteristics” factor while noting that other factors also supported detention.

  1. Independent review by the district court. The Fifth Circuit found it “evident” that the district court conducted a de novo review and made an independent determination, satisfying the Rueben standard for reviewing a magistrate judge’s detention order.
  2. Evasion and concealment as indicators of nonappearance risk. The panel treated the arrest conduct (noncompliance, flight, struggle, and biting) as direct evidence of an inclination to evade authorities. It then combined that with evidence suggesting longer-term avoidance: three years of unauthorized presence with no linked records and no known stable residence or employment. This synthesis matters: the panel did not treat the flight inference as resting solely on a single impulsive episode.
  3. Unknown ties as an affirmative risk factor. Rather than requiring the Government to disprove ties, the court treated the record’s absence of ties (unknown residence, unknown employment, unknown community connections) as supporting detention—particularly when paired with attempted evasion.
  4. Alleged burden-shifting did not warrant reversal on this record. Perez-Perez pointed to the district court’s statement that he had “not contradicted” the Government’s position with witnesses or evidence. The Fifth Circuit did not definitively endorse that phrasing, but held that “even accepting” Perez-Perez’s interpretation, the record as a whole supported detention under Rueben’s deferential approach. In effect, the panel treated any arguable burden-shifting as non-dispositive given the strength of the Government’s showing.
  5. Government’s “cannot predict” remark was not a concession. The court rejected the argument that a prosecutor’s statement about being unable to “prospectively predict” future behavior undermined the burden. The Government’s proof was evidentiary and circumstantial (past evasion, lack of ties), not predictive speculation.
  6. No reliance on immigration detainer. Perez-Perez argued the court improperly considered an immigration detainer and deportation risk. The Fifth Circuit found the order did not mention either, distinguishing United States v. Esquivel-Bataz where a detainer was mentioned, but treated there as relevant only to the practical effect on release rather than as a detention factor itself.
  7. Other § 3142(g) factors also pointed toward detention. Although not required to be addressed explicitly on this record, the panel noted: (i) the nature and circumstances involved an alleged assault on a federal officer to avoid arrest with resulting medical attention; and (ii) weight of evidence included testimony about photographs and blood, supporting the Government’s proof.

C. Impact

Because the opinion is not designated for publication under 5th Cir. R. 47.5, its formal precedential force is limited. Still, it has practical, persuasive value in at least three ways:

  • Reinforcement of “attempted evasion” as a flight-risk driver. The case consolidates Fifth Circuit practice (Sims, Wright) that evasion at arrest can weigh heavily toward detention, especially when the record lacks stabilizing ties.
  • Record-based affirmance despite arguable burden-shifting language. The panel’s approach signals that on appeal, detention orders may be affirmed where the evidentiary record is robust, even if a defendant can identify debatable phrasing in the district court’s order, so long as no clear legal error drives the outcome.
  • Careful handling of immigration-related arguments. The opinion implicitly advises litigants and judges to separate (a) immigration status and detainers as such from (b) concrete indicia of nonappearance risk (identity uncertainty, lack of verifiable residence/employment, demonstrated evasion). The panel affirmed without needing to rely on a detainer, and it highlighted the absence of detainer discussion in the order.

4. Complex Concepts Simplified

  • Pretrial detention (Bail Reform Act). Federal courts may detain a defendant before trial if the Government shows that no set of release conditions will reasonably assure (i) the defendant’s appearance in court and/or (ii) community safety.
  • 18 U.S.C. § 3142(g) factors. Courts consider: (1) nature/circumstances of the offense; (2) weight of the evidence; (3) history/characteristics (ties, employment, residence, criminal history, past conduct); and (4) danger posed by release.
  • “De novo” review by the district court. When reviewing a magistrate judge’s detention order, the district judge must make an independent decision, not merely defer to the magistrate.
  • “Preponderance of the evidence” (flight risk). The Government must show it is more likely than not that no conditions will reasonably assure the defendant’s appearance.
  • “Abuse of discretion” / deferential appellate review. On appeal, the Fifth Circuit does not re-try the detention hearing. It asks whether the lower court’s decision is supported by the record and free from legal error.
  • Burden-shifting concern. A court cannot require the defendant to prove he will appear; the Government bears the burden. But appellate courts may still affirm if the record independently supports detention and any problematic wording did not drive the result.

5. Conclusion

United States v. Perez-Perez underscores that attempted evasion at arrest, combined with unknown or unverifiable community ties and identity/residence/employment information, can justify pretrial detention for flight risk under 18 U.S.C. § 3142(g). The Fifth Circuit also reaffirmed a highly deferential appellate posture: even where a defendant plausibly argues that the district court’s phrasing flirted with burden-shifting contrary to United States v. Trosper, affirmance is likely if the evidentiary record as a whole supports detention under United States v. Rueben and related standards.
