United States v. Maria Molina-Isidoro
884 F.3d 287
5th Cir.2018Background
- Molina attempted to enter the U.S. at an El Paso land border crossing; CBP x-ray and inspection of her suitcase revealed a hidden compartment containing 4.32 kg of methamphetamine.
- Molina admitted no one could have placed the drugs in the suitcase without her knowledge, gave inconsistent travel details, and invoked a lawyer during questioning.
- At or around the same time, agents conducted a warrantless, non‑forensic/manual search of Molina’s cell phone (looking at WhatsApp and Uber) without consent and found incriminating messages.
- The government retained the phone but did not perform a forensic extraction.
- Molina moved to suppress the phone evidence; the district court denied suppression (concluding Riley did not control the border context and that reasonable suspicion existed).
- Molina was convicted after a stipulated bench trial; the Fifth Circuit affirmed, holding the officers reasonably relied on existing border‑search precedent (and therefore acted in good faith).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Riley requires a warrant for border searches of cell phones | Riley’s heightened privacy rationale applies at the border; warrant required for phone searches | Riley left open exceptions; longstanding border‑search doctrine permits warrantless device searches | Court declined to decide Riley’s reach; resolved on good‑faith grounds — officers reasonably relied on existing precedent |
| Whether the phone search here required any level of suspicion | Phone searches are highly invasive; at least reasonable suspicion or a warrant required | Probable cause existed here; even if lesser standard applied, officers had probable cause | Officers had probable cause to search; good‑faith exception applies; evidence not suppressed |
| Whether the post‑discovery shift from border inspection to criminal investigation vitiates border‑search authority | Discovery of contraband turned the encounter into a law‑enforcement investigation, triggering higher Fourth Amendment protections | Existing caselaw treats such searches at the border as still within border‑search authority; agents reasonably believed authority continued | Court found it reasonable for agents to view the search as within border authority; good‑faith supports admission |
| Whether the exclusionary rule requires suppression when officers reasonably rely on extant caselaw | Suppression required if search later deemed unconstitutional | Good‑faith exception permits admission when officers reasonably relied on prevailing law | Applied good‑faith exception (Leon/Davis); affirmed conviction |
