1:15 PM: Police are in the (corrected) West Duwamish Greenbelt between Riverview and West Marginal Way, where they’d gone because of a vehicle possibly with stolen plates, found but on fire. They’ve told dispatch that the fire appears to have been set; SFD has responded too, but it’s apparently happening in a tough-to-access place. They’ve also reported that the burning van has had two explosions – so if you’re in the area and think you’ve heard shots, that’s probably what you heard. So far no description of suspect(s) in the arson but the investigation and response continues.

3:02 PM: The vehicle was reported fully engulfed in flames at one point and described as a van possibly belonging to a local nonprofit.
