United States v. Caballero
178 F. Supp. 3d 1008
S.D. Cal.2016Background
- Defendant Caballero crossed into the U.S. at the Calexico Port of Entry in a car containing 15 kg methamphetamine and 1 kg heroin hidden in the gas tank; he was arrested.
- Agents conducted a manual/cursory search of a cell phone in custody several hours after arrest and discovered a photo of a large sum of money.
- Caballero moved to suppress the photo and the officers’ observations, relying on Riley v. California (warrant requirement for cell‑phone searches incident to arrest).
- Government invoked the border search doctrine (Flores‑Montano and Ninth Circuit precedent) to justify a warrantless cursory search at the port of entry.
- The Court found Caballero had standing to contest the phone search, concluded Cotterman ( Ninth Circuit en banc) controls, and denied suppression; it also rejected suppression of post‑arrest statements as voluntary.
Issues
| Issue | Plaintiff's Argument (Caballero) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Standing to challenge phone search | Caballero used and possessed the LG phone and did not consent to the search. | Government contested standing. | Court: Caballero has standing based on possession/use and lack of consent. |
| Whether Riley's warrant rule applies to cell‑phone searches at the border after arrest | Riley requires a warrant for cell‑phone searches incident to arrest; thus the photo should be suppressed. | Border search exception and Ninth Circuit precedent allow warrantless manual/cursory searches of electronic devices at ports of entry. | Court: Cotterman and border‑search doctrine control; Riley not clearly irreconcilable—warrantless cursory search permitted; suppression denied. |
| Whether the search required reasonable particularized suspicion or a warrant (manual v. forensic) | Post‑arrest cell‑phone search is highly intrusive and would require a warrant under Riley. | Cotterman permits cursory/manual searches without suspicion; forensic searches need reasonable particularized suspicion. | Court: The limited manual search here fit within Cotterman’s allowance; reasonable particularized suspicion existed given discovery of large quantities of drugs. |
| Exclusionary rule / Good‑faith exception | If search unconstitutional, evidence should be suppressed. | Officers reasonably relied on binding circuit precedent; good‑faith exception applies. | Court: Even if Riley applied, good‑faith exception would bar suppression because officers reasonably relied on existing precedent. |
| Voluntariness of post‑arrest statements / Miranda waiver | Caballero contended waiver/incriminating statements were involuntary after arrest. | Government showed Miranda warnings given and video corroborating voluntariness. | Court: Waiver and statements were voluntary; suppression of statements denied. |
