Authorities withheld the name of the fatally wounded man, who was in his 30s.
No officers were injured.
The man reportedly called West Covina Police to ask for an Armenian-speaking officer to be dispatched to his home. When the officer arrived, the man reportedly asked the officer to drive him to another location. A confrontation ensued, and the man somehow drove off in the officer's patrol vehicle.
Officers pursued the stolen cruiser at speeds approaching 100 miles per hour until a police SUV crashed into its driver's side door to make it stop in a Glendale parking lot.
The fatal shooting involved officers from the West Covina Police Department, Los Angeles County Sheriff's Sgt. William Cotter told Fox 11.
