1:01 AM: Lots of questions this past half-hour about a helicopter just south of the city/county border. Flight-tracking showed it was Guardian One but there was little discussion on the scanner and no reports of ground activity, so we didn’t know what it was up to until this tweet just after it left the area: “Assisted White Center patrol on person with a gun call in 18 Ave SW. Led patrol in to person in front yard of house. Subject is detained.” That would be a King County Sheriff’s Office case and we’ll follow up later this morning.

ADDED 5:14 PM: We finally have additional information to share. From KCSO spokesperson Sgt. Cindi West: “Around midnight, we responded to the area of the 10400 block of 18 Ave SW for a report of a suicidal man who possibly had a gun. We contacted the man in the area and did not locate a gun. The man was transported to a hospital for a mental-health evaluation. The man is a 66 year old living in the vicinity.”
