In an unprecedented filing in California history, the San Francisco District Attorney’s office has announced a former police officer will face a variety of homicide charges for the 2017 shooting death of an alleged carjacking suspect. 

San Francisco District Attorney Chesa Boudin announced the decision to charge former officer Chris Samayoa via a Twitter post on Monday. 

“Today, my office filed homicide charges against the former officer who shot and killed Keita O’Neil, an unarmed, Black man in 2017,” he wrote. “As far as we are aware, this is the first time in San Francisco history that an officer has been prosecuted for homicide.”
