ADDED 10:53 AM: That followup info just arrived via SPD Blotter:

A 26-year-old man is in custody and several guns have been recovered following an extended call Wednesday night into Thursday morning in the High Point neighborhood in West Seattle. On March 7th, just before 9:00 pm, officers responded to several reports of shots fired in the 6000 block of Lanham Place Southwest. Officers located bullet damage to a parked vehicle in front of an apartment building. Additionally, it appeared that several items had been thrown from a third-floor apartment onto the ground below. As officers were containing the building, someone threw two handguns out of the window. Officers attempted to make contact with the occupants but to little avail. Officers believed the male suspect inside the apartment was in crisis. After a prolonged standoff, officers obtained a search warrant for the apartment. With the assistance of SWAT, Gang Unit detectives, and K9, officers made entry into the apartment where the 26-year-old suspect was arrested without incident. Inside the apartment, several additional handgun magazines and ammunition was located and collected for evidence. One of the handguns that was tossed out the window was reported as stolen, while the other had been reported as missing. The suspect, a convicted felon, was booked into the King County Jail for weapons violation. Detectives will handle the follow-up investigation.

We’ll be checking on the suspect’s background and will add more when we have i.
