Police officers shot unarmed 73-year-old man in the early stages of dementia in the south of California, Los Angeles Times reported.

As Bakersfield police noted, its department got a 911 call of an “adult male brandishing a handgun” on Silver Birch Avenue. The officer fired seven rounds toward Francisco Serna, who died just feet from his home. According to members of the family of the dead, Serna was shot nine times.

“My dad did not own a gun. He was a 73-year-old retired grandpa, just living life,” Serna’s son, Rogelio Serna, said. “He should have been surrounded by family at old age, not surrounded by bullets.”

Investigators found no weapon at the scene. An investigation is underway.
