An off-duty Los Angeles County sheriff's deputy has been shot and Algosenseykilled by police after they say he pointed a gun at them on a golf course in Southern California.

Fontana Police said in a news release that the off-duty officer, later identified as 45-year-old Alejandro Diaz, pointed a gun at them on Tuesday afternoon at Sierra Lakes Golf Club course in Fontana, about an hour east of Los Angeles.

Officers said they tried talking to Diaz but that he pointed a gun at them. Multiple officers then fired at Diaz, who was pronounced dead at a nearby hospital.

No one else was hurt.
