United States v. Marcos Mendez
103 F.4th 1303
7th Cir.2024Background
- Marcos Mendez was stopped by customs at O'Hare International Airport after returning from Ecuador, based on a CBP “lookout” due to prior arrest related to child pornography and suspicious travel history.
- During secondary inspection, Mendez gave agents his cell phone and passcode; a manual search by agents uncovered apparent child pornography.
- Agents then performed a more in-depth “forensic” search, downloading and extracting data from Mendez’s devices, which confirmed additional illicit content.
- Mendez's motion to suppress the evidence argued the searches violated the Fourth Amendment as they lacked a warrant, probable cause, or reasonable suspicion, citing Riley v. California and Carpenter v. United States.
- The district court denied the motion, holding that the border search exception applied and reasonable suspicion existed; Mendez pled guilty but preserved the suppression issue on appeal.
- The Seventh Circuit reviewed the legal question de novo and affirmed the denial of suppression.
Issues
| Issue | Mendez's Argument | Government's Argument | Held |
|---|---|---|---|
| Whether border searches of electronic devices need a warrant or probable cause | Riley and Carpenter require heightened protection for cell phone data; warrant, probable cause, or at least reasonable suspicion needed | Border search exception applies; no warrant or probable cause required, extends to electronics | Border searches, including for electronics, do not require a warrant or probable cause |
| Whether a manual cell phone search at the border is "routine" or "non-routine" | All electronic device searches are highly intrusive and need at least reasonable suspicion | Brief, manual border searches of electronics are routine, no suspicion needed | Manual search is a routine border search; no individualized suspicion required |
| Whether Riley v. California applies to border searches | Riley’s logic extends to borders due to privacy concerns | Riley applies only to search-incident-to-arrest, not border searches | Riley does not alter the border search exception; it is context-specific and inapplicable here |
| Whether a forensic search after finding contraband in a manual search requires suspicion | Forensic search requires reasonable suspicion at minimum | Any further search after finding contraband is justified | Even if reasonableness standard applied, agents had suspicion after manual search revealed contraband |
