(CNN) A former San Francisco Police officer was charged with homicide Monday in connection with a 2017 on-duty shooting.
The city's district attorney's office said in a news release that it believes this is the first time a city law enforcement officer has been charged with an on-duty homicide.
Former San Francisco officer Chris Samayoa is charged with fatally shooting 42-year-old Keita O'Neil, a Black man suspected of carjacking a California State Lottery minivan, according to the news release.
Samayoa has been charged with voluntary manslaughter, involuntary manslaughter, assault with a semiautomatic firearm, assault by police officer and discharge of a firearm with gross negligence, the release said.
The former officer is expected to surrender on the warrant later this week, according to the DA's office.
The San Francisco Police Officers Association (SFPOA) said they are supporting the former officer and his family after learning of the charges.
San Francisco Supervisor Shamann Walton, whose district includes the area where the deadly shooting occurred, expressed satisfaction with the charges. »
