Two men have been charged with killing a 6-year-old boy who was shot as he played in the driveway of his Azusa home.

Los Angeles County prosecutors filed murder charges Tuesday against 21-year-old Richard Gomez, of Azusa, and Mathew Loza, 20, of West Covina. If convicted, they could face life in prison with chance of parole.

Both remain jailed on $1 million bail each.

Authorities say Jessie Valencia was shot last Friday as he played with a remote-controlled car.

Azusa police Lt. Mike Bertelsen says investigators believe Loza was at Gomez's home across the street when he targeted the boy with a scoped rifle and shot him.

However, investigators are still trying to determine whether Loza knew the gun was loaded when he pulled the trigger.
