The latest on the fatal shooting of a man by deputies in Los Angeles County (all times local):

12:22 p.m.

Authorities say the man fatally shot by Los Angeles Sheriff's deputies held a gun as he lay dying on the ground.

A close up from a security video released by the Sheriff's Department on Sunday shows 28-year-old Nicholas Robertson stretched on the ground with a gun in his hand.

Sheriff homicide Cpt. Steven Katz says two deputies fired 33 bullets at the gunman after he refused to drop the gun and walked across a busy street to a gas station where a family was pumping gas.

Katz says Robertson walked down a residential street and then along a busy commercial area holding the gun and acting strangely.

Katz says witnesses reported he fired six to seven shots in the air and briefly went into a car wash and a pizza parlor before the deputies arrived.

9:25 a.m.

The Los Angeles County coroner's office has identified the man shot by sheriff's deputies as Nicholas Robertson, 28, of Lynwood.

Two Los Angeles County Sheriff's deputies killed Robertson in a shooting captured on video that appears to show a man being hit with gunfire as he walked away from the deputies.

The deputies were responding Saturday to reports of a man walking in Lynwood and firing a gun into the air around 11 a.m., Deputy Juanita Navarro-Suarez said in a statement.

When the deputies encountered the man in front of a gas station, they ordered him to drop the gun but he did not comply.

The video shows the deputies firing several rounds after the man fell and crawled on the ground. He died at the scene.

An autopsy is pending.
