Update 4:46 p.m.: The woman was transported to the hospital in an ambulance after being rolled out of her home in a wheelchair. While the woman originally indicated to dispatchers that she would harm herself with a gun, no gun was found in her home, according to Capt. Hart. He said he believed the woman may or may not have had a bad reaction to medication. 

Earlier: San Francisco Police Department crisis negotiators are attempting to convince a 75-year-old woman with a gun to peacefully leave her home near 27th and Dolores streets, according to SFPD Ingleside Captain Jack Hart.

At around 3:18 p.m. Friday, the 200 block of 27th Street (between Church and Dolores) was swarming with dozens of police officers asking the armed woman to leave her home. An ambulance was driven to near the woman’s house to show the woman the police mean no harm. The woman may have dementia, according to Hart.

We’re currently trying to communicate with them and have them peacefully walk out on their own accord and get services to them,” said SFPD spokesman Officer Robert Rueca. 

Officers ushered neighbors in and out of the blocked-off scene, as police gathered outside of a light green house on the 200 block. At around 3:50 p.m. officers approached the woman’s house with a shield raised. An officer was armed with a less-lethal shotgun, which likely fires beanbag rounds.

Rueca said that the immediate area is blocked off to car and pedestrian traffic.
