The family of Jessica Williams, the 29-year-old shot and killed by police in Bayview in May, has filed a federal lawsuit against both the city of San Francisco and the SFPD officer who shot her. 

As KRON reports, the lawsuit alleges that Sgt. Justin Erb violated Williams' constitutional rights after pulling her over at Elmira and Shafter streets around 10am on May 19th. Williams, who was unarmed, was driving a Honda that was suspected of being stolen. 

Williams had allegedly tried to drive away when officers tried to stop her, but didn't make it more than 100 feet before crashing into a parked truck. It remains unclear why Erb opened fire; the city attorney's office has argued that Williams was driving the car towards the officers, with the intent of striking them. 

In the suit, Williams' family alleges that Erb used excessive and "objectively unreasonable" force. 

An autopsy showed that Williams, who was homeless, died from a single shot to the chest. She was also found to have meth in her system. However, she was not pregnant, as initially rumored. 

The incident, in addition to police shootings of Luis Gongora, in the Mission, and Mario Woods, also in the Bayview, led to the resignation of San Francisco’s police chief Greg Suhr, who had already been under pressure from protesters. He resigned the afternoon Williams was shot, and acting chief Toney Chaplin has assumed his role while a new chief is sought.
