## Facts

- Four inmates escaped from a District of Columbia detention facility by crawling through a window and descending on a knotted bedsheet.
- Each was later recaptured after remaining at large for varying periods and was charged with escape from federal custody under 18 U.S.C. § 751(a).
- At trial, defendants sought to introduce evidence of allegedly coercive jail conditions, including beatings and death threats by guards, inadequate medical care, and repeated fires causing smoke and poor air quality.
- Defendants argued these conditions supported duress or necessity and negated criminal intent.
- In separate district court proceedings, trial courts refused to submit a duress/necessity instruction and limited or neutralized prison-conditions evidence, reasoning defendants failed to show any effort to surrender once outside the allegedly coercive conditions.
- The court of appeals reversed for new trials, holding the jury should consider prison-conditions evidence on intent and should be instructed that escape is a continuing offense.
- The Supreme Court granted review.

## Issues

1. Under 18 U.S.C. § 751(a), must the government prove an escapee acted with an intent to avoid “confinement” (as distinct from intolerable conditions), or is it sufficient to prove knowing unauthorized departure from custody?
2. What evidentiary showing is required for a defendant charged with escape to receive a duress or necessity jury instruction based on prison conditions?
3. Is escape under § 751(a) a continuing offense that includes remaining away from custody after the initial departure?

## Decision

- The Supreme Court reversed the court of appeals and reinstated the convictions.
- For § 751(a), the prosecution meets its burden by proving the defendant knew his actions would result in leaving physical confinement without permission; no additional “intent to avoid confinement” element is required.
- Escape is a continuing offense; justification defenses in escape cases must address both the initial departure and continued absence.
- A defendant is not entitled to a duress/necessity instruction without evidence of a bona fide effort to surrender or return to custody as soon as the claimed duress or necessity loses its coercive force.

## Legal Principles

- 18 U.S.C. § 751(a) is satisfied when an escapee knowingly leaves custody without permission; prison conditions do not negate this mens rea.
- Escape is a continuing offense that includes remaining at large, not merely the moment of departure.
- Duress or necessity in an escape prosecution requires evidence justifying continued absence from custody as well as the initial escape.
- An indispensable element of duress/necessity in escape cases is evidence of a prompt, bona fide effort to surrender or return to custody once coercion or necessity abates; absent such evidence, no jury instruction is warranted.

## Conclusion

The Court held that § 751(a) requires proof of knowing unauthorized departure, rejected a heightened “intent to avoid confinement” theory, and required escape defendants invoking duress or necessity to present evidence of prompt, bona fide surrender once the claimed coercion ends, consistent with escape’s status as a continuing offense.
