2015 WL 9274916
E.D.N.Y.2015Background
- Defendant Adamou Djibo, an outbound passenger at JFK, was stopped during a CBP "border enforcement exam" after HSI was alerted by a cooperating witness who had implicated Djibo in heroin importations.
- CBP inspected Djibo’s luggage, found no currency or drugs, but discovered multiple cell phones, including an iPhone5.
- HSI Special Agent Wilburt, standing nearby, asked Djibo for the iPhone’s phone number and passcode during the examination; Djibo provided the passcode before being arrested and read Miranda rights.
- After arrest, agents ran a Cellebrite extraction (a 921‑page “peek”) of the phone without a warrant; a month later they obtained a warrant and performed a full forensic search.
- Djibo moved to suppress his statements (passcode) and all data from the phone, arguing Miranda and Fourth Amendment violations; the government argued border‑search authority, inevitable discovery (IP‑Box), and that the warranted search was independent.
Issues
| Issue | Plaintiff's Argument (Djibo) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Were Wilburt’s questions (phone number/passcode) custodial Miranda interrogation? | Questions occurred in a private area during a border exam while Djibo was not free to leave; therefore custodial and should have been Mirandized. | The interaction was a routine border enforcement exam of an outbound passenger, noncustodial, so Miranda not required. | Court held the questioning was custodial; statements suppressed. |
| Was the warrantless “peek” (Cellebrite extraction) admissible as a border search? | The phone search exceeded permissible border search scope; initial exam was for currency and concluded before phone interrogation—thus unlawful. | Border search exception allowed inspection of electronic devices for evidence of currency/bulk cash smuggling. | Court held the initial warrantless extraction was unlawful and suppressed data obtained from it. |
| Was the subsequent warranted forensic search tainted fruit of the unlawful initial search? | The warrant and forensic search were informed by the impermissible peek; thus fruit of poisonous tree and must be suppressed. | The warrant was supported by independent sources (cooperator, other evidence) and would have been issued regardless. | Court found the forensic warrant search was fruit of the illegal peek and suppressed its fruits. |
| Could the government show inevitable discovery (e.g., by using an IP‑Box to brute‑force the passcode)? | Government cannot meet burden: offered speculative testimony; no proof IP‑Box would reliably or safely access this iOS version. | IP‑Box and other forensic techniques could have broken the passcode; so data would have been discovered inevitably. | Court rejected inevitable discovery: government’s evidence was speculative and insufficient; suppression sustained. |
