7:52 PM: Thanks for the texts about a big police response north of The Junction. We’re just arriving in the area where police have converged, near California/Dakota. We know they’re focused on an apartment building with a possible suspect inside but we don’t yet know why. Updates to come.

7:58 PM: More police vehicles in the northbound lane of California just south of Dakota, and through traffic is having to go through the center lane to get around it. Avoid this area if you can. Police at the scene aren’t saying what the suspect is wanted for.

8:09 PM: From the scanner – the man on whom police are focused is believed to have a gun.

8:18 PM: California/Andover and vicinity is blocked off by police, so if you have to get to/through this area, take the side streets to the west – this is all happening east of California. It does appear from our vantage point, though, that diverted traffic is traveling along 42nd, including a Metro bus.

8:33 PM: We’ve finally been able to obtain information on what started this. “Person in crisis” situation – armed person threatening self-harm, according to Det. Patrick Michaud with the media-relations unit, reached by phone.

9:05 PM: SWAT officers are arriving to assist. The new “mobile precinct” vehicle (photo above) has been in the area for a while, too.

9:43 PM: Officers are in contact with the man now. Awaiting word that he’s in custody. We have a crew at the scene as well and asking them to confirm. All indications from radio traffic is that the situation is now under control. An ambulance is being brought in and police are going in to “clear the residence.”

9:51 PM: Our crew confirms that the man is out of the apartment and this has been resolved peacefully. California is going to stay closed for a while, per scanner, but Andover will be reopened soon.

10:15 PM: Our crew has just talked with a sergeant at the scene. The man was in the apartment by himself all along. California SW is likely to reopen within half an hour – right now they’re waiting for the SWAT officers to pack up and clear out.

ADDED MONDAY MORNING: As a commenter points out, when stories involve suicide or threats of self-harm, we usually include info about the Crisis Clinic, which is always there to help, including a 24-hour hotline at 206-461-3222.
