2:38 PM: Thanks for the tips. Police tell us they are dealing with a person in crisis, possibly armed, near 36th/Roxbury, and have blocked Roxbury in that area. They tell us nearby Summit Atlas middle/high school is in lockdown as a result. No injuries reported thus far but avoid the area.
3:27 PM: Not resolved yet. A dispatcher recapping the situation described it as having started when the person “brandished a rifle at a neighbor’s window” and was then seen by officers with “a pistol.” They are reported to be inside a house.
4:06 PM: As noted in comments, Summit Atlas has since let out for the day. Meantime, SWAT team officers have joined the response. The person who’s the focus of all this is reported to be a man in his 60s.
5:04 PM: Not resolved yet. Note for traffic purposes that Cambridge also is blocked west of 35th SW.
5:34 PM: Officers are continuing to use a PA system to ask the man to surrender.
5:58 PM: If you just heard an explosion in the area, that’s a “flash-bang” deployed by SWAT. … Shortly after that, another one.
7:13 PM: They’ve now advised the man via the PA that they have obtained a search warrant and if he doesn’t come out, they’re going in.
7:31 PM: Still trying to convince him to surrender, with another flashbang, in the standoff’s sixth hour.
8:01 PM: Now seventh hour. Police report the man has been firing a “pellet” gun among other erratic behavior.
9:01 PM: Eighth hour. SWAT officers are continuing to try different tactics, and continuing to tell him via PA that he’s under arrest and needs to surrender.
10:02 PM: Ninth hour. No change.
10:14 PM: SWAT officers reported to dispatch that they’ve moved in and are taking him into custody. They’re calling for SFD to come check him out for exposure to gas (which they used multiple times earlier) and for “Taser deployment.”
10:26 PM: Officers tell dispatch he’ll be taken to the hospital.
