About the helicopter over south West Seattle and vicinity

4:23 PM: That’s the King County Sheriff’s Office helicopter Guardian One, which often assists other agencies. We’re working to find out what it’s doing right now – nothing big has been on the SPD frequency, though one officer radio’ed in that they’re “with county.”

4:50 PM: KCSO says it wasn’t them; we’ve been driving around looking on the ground, no sign of a response. So we still don’t know yet.
