State v. Sines, 404 P.3d 1060

Background

In 2006 a housekeeper and another employee of defendant took a nine‑year‑old child T’s underwear from a laundry hamper, gave it to a DHS contact who arranged delivery to a deputy (Detective Quick), and it was sent to the state crime lab. Lab testing found spermatozoa that later matched defendant’s DNA; a warrant based on those results led to further seizures and convictions on sexual abuse counts.
Trial court denied defendant’s pretrial motion to suppress evidence derived from the underwear, finding the employees’ actions were private and that Quick had an objectively reasonable belief (probable cause) the underwear contained evidence; the court also treated the lab testing as confirmatory.
On initial appeal this court reversed under the Oregon Constitution (Article I, §9); the Oregon Supreme Court reversed that holding as to state constitutional grounds, concluding the employees’ conduct was private, and remanded to decide the Fourth Amendment issue and other assignments of error.
On remand this court held the employees’ conduct was private for Fourth Amendment purposes as well, but concluded the state crime lab’s warrantless testing of the underwear was a search under both the Fourth Amendment and Article I, §9.
The court held the lab testing exceeded the scope of the private search (and Quick’s inspection) because microscopic and chemical testing revealed previously unobservable medical and DNA information; no warrant or exception was shown, so suppression was required and the convictions reversed as not harmless.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Sines)	Held
Whether employees’ seizure of underwear was state action	Employees acted independently; not state actors	Employees acted at DHS direction/acquiescence, so their search was state action	Employees’ conduct was private, not state action (followed Supreme Court Sines II reasoning)
Whether Detective Quick’s acceptance of underwear was an unlawful seizure	Acceptance was lawful; officer had an objectively reasonable belief the underwear was evidence	Acceptance was an unlawful warrantless seizure	Court assumed (without deciding) Quick’s acceptance lawful and focused on testing
Whether crime‑lab testing of underwear was a Fourth Amendment search	Testing was confirmatory of evidence police already had probable cause to believe existed (Owens)	Testing invaded defendant’s privacy interest and required a warrant	Testing was a search: it exceeded scope of private search and could reveal private medical/DNA facts; no warrant or exception — unconstitutional
Whether the Article I, §9 analysis differs from Fourth Amendment outcome	Owens allows confirmatory testing without warrant when police have probable cause	Article I, §9 protects privacy in effects; testing revealed secret information and required warrant	Testing also violated Article I, §9 for same reasons; Owens limited to narrow contraband/confirmatory contexts and does not justify these tests
