ARLINGTON — Detectives with the Snohomish County Sheriff’s Office are looking to speak with anyone who may have witnessed a vehicle collision that left an 18-year-old Stanwood woman, a passenger in the vehicle, dead at the scene on Sunday, Feb. 16.

The incident occurred around 11:30 a.m. that day, when a black Lexus traveling at a high rate of speed on 240th Street NE left the roadway between 123rd and 131st avenues. The 19-year-old driver and an 18-year-old male passenger, both from Arlington, sustained minor injuries.

Detectives are interested in speaking to one witness in particular — a white male believed to be in his 50s or 60s, with gray hair, wearing a gray sweatshirt, walking eastbound on 240th Street NE at the time of the accident. Anyone else with information about the incident is asked to call the Sheriff’s Office Anonymous Tip Line at 425-388-3845.

The release of the name of the female victim is pending from the Snohomish County Medical Examiner. The crash remains under investigation by the Sheriff’s Office Collision Investigation Unit.
