953 F.3d 1047
8th Cir.2020Background
- On Jan. 1, 2017, Paul Donnelly, a non‑police acquaintance, took Dennis Suellentrop’s cell phone, viewed images and videos and discovered child‑pornography depicting Suellentrop’s infant daughter, and showed some images to others and to Deputy Roberts.
- Donnelly handed the phone to Deputy Roberts; officers turned it off and kept it. Suellentrop waived Miranda rights but refused consent to search his home or phone.
- Detective Poe later took custody of the phone, consulted a state prosecutor, and obtained a state search warrant authorizing search of the residence and electronic storage devices; officers searched the residence and later performed a forensic exam of the phone that uncovered additional child‑pornography.
- Federal agents obtained a separate federal warrant and conducted their own forensic examination; a grand jury charged Suellentrop with multiple counts of production and possession of child pornography.
- Suellentrop moved to suppress phone evidence, arguing (1) Donnelly acted as a government agent so his private search triggered the Fourth Amendment, and (2) the state warrant did not authorize searching the phone. The district court denied suppression; Suellentrop appealed.
Issues
| Issue | Suellentrop's Argument | Government's Argument | Held |
|---|---|---|---|
| Whether Donnelly’s initial search and subsequent handing/showing of phone to police implicated the Fourth Amendment | Donnelly acted as a government agent when he showed/unlocked the phone, so the private‑search rule does not apply | Donnelly acted privately; the Fourth Amendment does not bar the government from reexamining materials already viewed in a private search, so images Donnelly viewed are admissible | Donnelly acted on his own; images he viewed privately could be used by police (private‑search doctrine) |
| Whether the state search warrant authorized searching the phone that had been seized before the warrant issued | Warrant did not cover the phone; searching it exceeded the warrant’s scope | Officers reasonably believed the warrant covered electronic devices seized at the residence, including the phone; prosecutor advised them accordingly | Officers’ interpretation was objectively reasonable; search fell within constitutionally tolerated honest mistakes; state warrant justified the phone search |
| Whether officers’ reliance on the state warrant was in bad faith (Poe allegedly omitted the phone from the warrant to search incident to arrest) | Poe intentionally omitted the phone and did not rely on the warrant | Poe sought and believed the warrant authorized a phone search, listed the phone on the inventory, and consulted the prosecutor | District court credited Poe’s testimony; no clear error — good‑faith reliance holds |
| Whether any other safeguards (independent federal warrant or limits on re‑examination) affect admissibility | Evidence should be suppressed if state search was invalid or private‑search protections were breached | Federal warrant provided an independent basis and private‑search plus state‑warrant grounds suffice | Court affirmed denial of suppression on private‑search and state‑warrant grounds (federal warrant also available as independent source) |
