A man who shot and killed himself Monday afternoon after Richmond police stopped him was an off-duty San Francisco police officer, according to a spokesman for SFPD.
At about 1:30 p.m., a Richmond police officer conducted a traffic stop in the Hilltop mall parking lot near J.C. Penney, spokesman Lt. Felix Tan said.
After stopping the vehicle, the officer heard a gunshot and went back to his patrol vehicle to ask for help.
Tan said officers weren't sure what happened because the windows of the suspect's vehicle were heavily tinted. Officers used beanbag rounds to break the windows of the vehicle and found the man dead inside.
SFPD spokeswoman Officer Grace Gatpandan confirmed late Monday night the deceased officer, who was later identified as 49-year-old Antonio Cacatian, was a nine-year veteran of the department.
San Francisco police spokeswoman Giselle Linane says Cacatian was the subject of a criminal investigation involving multiple law enforcement agencies. Linane declined to discuss the investigation further.
The police chief and command staff expressed their condolences to the officer's family Monday, she said.

Tan said Richmond police and the Contra Costa County District Attorney's Office each have opened investigations into the death.
