State v. Humphrey

Holding, in one sentence

A stop occurred at the moment the officer activated her emergency lights and parked angled toward the defendant — before any words were spoken — and that stop was supported by reasonable suspicion at that instant, based on the specific combination of facts known at the time.

Facts, as stated in the opinion

Eugene officers responded within minutes to reports that two people had been struck with a stick. A victim described the assailant to Officer Mueth as a Black male, about 45–50 years old, and indicated the direction he had run; another bystander added a gray hooded sweatshirt and said he had just turned up the street. About 40 seconds after driving in that direction, Mueth encountered the defendant sitting alone at a bus stop roughly one block from the scene. She activated her emergency lights, parked canted toward him, and approached; a second officer parked similarly. After Miranda warnings, the defendant admitted an altercation and said he had struck a victim with a piece of bamboo. He later moved to suppress, arguing that he had been stopped when the lights were activated and that reasonable suspicion did not yet exist at that point.

What changed

• The court held, on these facts, that a targeted lights-and-positioning display can itself effect a stop under Article I, section 9. In the court's analysis, the stop began at the lights display, not at the first conversation.
• The case provides an example of how a description contributed to reasonable suspicion when corroborated by other facts — and includes a caution from the court that stops resting on generalized characteristics such as race may, in some circumstances, raise constitutional concerns.

What did not change

• A description based on race, sex, and approximate age, standing alone, was not held to be reasonable suspicion. In Humphrey, the description was one element among several (see Plain-English findings).
• Oregon's reasonable-suspicion framework was not replaced: an officer's subjective suspicion of a specific crime that is objectively reasonable on the facts known at the time the stop begins.
• The opinion does not address consent encounters, the mission of a traffic stop, or the probable-cause standard for an arrest.

Plain-English findings

• The court treated the emergency lights, directed at a specific person, as the start of the stop. The facts the court used to assess the stop were the facts known before that display; facts observed afterward were not the basis the court used to justify the stop at its inception.
• The corroboration described in the opinion, in the order it occurred, was: (1) a specific crime that had just been committed; (2) a report that was minutes old; (3) a known direction of flight; (4) a person found where that direction and the elapsed time would predict; and (5) that person was alone in the area at that place and time.
• The distinction drawn in the opinion is between a description plus that kind of time, place, and flight corroboration, and a description by itself. Only the first combination was before the court.
