United States v. Sheehan
838 F.3d 109
2d Cir.2016Background
- Sheehan planted a device in a Home Depot lighting fixture box and sent ransom letters and calls demanding payment to avoid further bombings; he admitted extortion at trial.
- The device contained a metal pipe, end caps, smokeless powder (from shotgun shells), wires, a nine‑volt battery (not connected), a pull‑string switch, and was affixed to a shelf; a robot‑disrupter shot the device and it detonated during rendering‑safe operations.
- FBI bomb experts testified the device was an IED/pipe bomb and could detonate by non‑electrical means (heat, shock, friction) or could be made electrically functional quickly with commonly available items; defense expert testified detonation was implausible absent unscrewing an end cap and that smokeless powder is stable.
- Jury convicted Sheehan of Hobbs Act extortion (18 U.S.C. § 1951) and using a destructive device during a crime of violence (18 U.S.C. § 924(c)(1)(B)(ii)); district court sentenced him to a consecutive 30‑year mandatory minimum on the § 924(c) count.
- On appeal Sheehan conceded extortion guilt and challenged only the § 924(c) conviction, raising: (1) insufficient evidence that the device was an “explosive bomb”; (2) improper combination‑of‑parts jury instruction; (3) failure to require subjective intent and to define “readily assembled”; and (4) prosecutorial misconduct in summation.
Issues
| Issue | Plaintiff's Argument (Sheehan) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Sufficiency: Was the device an “explosive bomb” under § 921(a)(4)(A)(i)? | Device was nonfunctional in its ordinary (electrical) mode and thus not an explosive bomb. | A device is an “explosive bomb” if it is capable of exploding by any means; experts testified it could detonate and was objectively designed as a weapon. | Affirmed: a device that is capable of exploding (even if not via its intended fuze) satisfies “explosive bomb”; jury could credit government experts. |
| Appropriateness of combination‑of‑parts instruction | Combination‑of‑parts theory applies only to incomplete/disassembled devices, so instruction was inapplicable. | § 921(a)(4)(C) covers “any combination of parts” and can reach partially assembled or defective but convertible devices; jury could find device partially incomplete. | Affirmed: instruction proper because statute covers combinations of parts and whether device was fully assembled is a factual question for the jury. |
| Need for subjective intent instruction / definition of “readily assembled” | Court should have instructed that conviction requires Sheehan’s subjective intent to build a destructive device and defined “readily assembled” to require possession of all components without “going shopping.” | Statute distinguishes objective “designed” from subjective “intended”; when components can only be assembled into a destructive device (or an inert model of that same device), objective design suffices; proof need not include possession of mundane readily‑available items. | Affirmed: no subjective‑intent instruction required because parts could only be assembled into a bomb (or inert model) and objective design rule applies; court rightly declined to require proof of possession of common items (e.g., tape). |
| Prosecutorial misconduct in summation | Government misstated evidence, attacked defense counsel/expert improperly, and thus deprived Sheehan of a fair trial. | Summation largely responded to defense arguments; comments were not flagrantly abusive and permissible rebuttal; no timely objections. | Affirmed: even if some comments were imperfect, they did not amount to flagrant abuse or undermine trial fairness given the record. |
