An unarmed 73-year-old with dementia who was shot and killed by police early Monday was struck nine times, the man's son said in a video posted to Facebook.
Serna, who was shot in a driveway near his home, died at the scene.
Police said the call was prompted by a report of a man with a firearm, but investigators canvassed the area after the shooting and did not recover a gun, Carruesco said.
In a statement obtained by the Associated Press, the Kern County coroner said Francisco Serna was declared dead on the scene at 1:15 a.m.
"My dad did not own a gun", Rogelio Serna told The Times.
Mr Serna's son Rogelio told the Times he was a retired grandfather who did not own a gun. "He should have been surrounded by family at old age, not surrounded by bullets".
The Bakersfield Police Department will hold a news conference this afternoon about an officer involved shooting that killed an elderly man in southwest Bakersfield yesterday, and KGET TV-17 is expected to air the news conference as it happens. Serna's family told a local news outlet that he "walks around with a cross".
Joanna Almeida, assistant professor of social work at Simmons College in Boston and lead author of the study, said the links between discrimination and anti-immigrant polices are "chilling" given President-elect Donald Trump's stance on the issue.
According to KBAK, Serna lived in Bakersfield with his wife, and one daughter.
Bakersfield police have not identified the officer who fired on Serna. Family members mourning his death revealed that Francisco Serna only recently diagnosed with dementia and that his health was taking a turn for the worse of late. And in October, Ugandan immigrant Alfred Olango was shot and killed in the San Diego suburb of El Cajon by officers responding to reports of an individual "not acting like himself".
The officer, whose name was not released, was placed on routine administrative leave.
