The man shot and killed by police on a Fontana golf course was identified as an off-duty Los Angeles County sheriff’s deputy Wednesday.

The incident began around 4 p.m. in the area of the Sierra Lakes Golf Club when authorities received a 911 call from a woman saying her husband had fired a gun at a wall inside their home, according to the Fontana Police Department.

The man was said to be distraught and drinking before allegedly firing the shots.

A caller then reported the man left the home and headed to the golf course carrying a gun. Authorities initially said the man was armed with two guns.

Fontana police officers responded to the golf course and confronted the man. Officers gave verbal commands before firing at the suspect, authorities said without elaborating.

Officers and paramedics began life-saving measures, and the man was taken to a hospital where he was pronounced dead, officials said. He was identified as Alejandro Diaz, 45.

Investigators have not confirmed if any shots were fired at officers, though none were injured.

Authorities have not said if the gun Diaz was allegedly armed with was his service weapon.

The Fontana Police Department is cooperating with the investigation, which was taken over by the San Bernardino County sheriff’s and district attorney’s offices, authorities said.
