Sacramento police released more than 50 video and audio clips Monday that add fresh details about the department's response following the fatal shooting of an unarmed black man.
The March 18 shooting of 22-year-old Stephon Clark sparked an outcry in California's capital and became the latest flashpoint in a national conversation about police shootings of young black men.
The police were responding to calls of someone breaking car windows. They said they thought Clark had a gun, but he was unarmed.
The new clips show several officers muting their microphones when they begin speaking with others and two officers administering CPR on Clark's motionless body more than five minutes after the shooting. They include dashboard and body-camera footage from officers arriving after the shooting, audio from two 911 calls and more video from a Sacramento County Sheriff's Department helicopter.
One of the newly released 911 calls appears to come from Clark's grandfather. Earlier released video footage showed Clark jumping over a fence into his grandparents' side yard, then being chased by police into the backyard, where he was shot.
