Five people were found dead, three of them children, in what appeared to be a murder-suicide in a home across the street from the Richard Nixon Library, police said Sunday.
A 14-year-old boy called 911 about 11 p.m. Saturday to report that his father had shot him and his brother at their condominium, said Sgt. Peter Rodriguez of the police department in Brea, which was investigating the shooting in neighboring Yorba Linda.
Police found the body of a woman on the doorstep. Inside, they found the bodies of a 5-year-old boy and two girls, ages 8 and 9. Officers also found the body of a man with a shotgun beneath him.
Police did not immediately know the motive for the shootings or the relationship of the victims.
The teenager who called 911 was hospitalized in stable condition, Rodriguez said.
"It is an extreme shock to this community," Rodriguez told radio station KNX-AM. "We're all taking this very hard."
Names of the victims were not released because relatives had not been notified.
Yorba Linda is a bedroom community in Orange County, 40 miles southeast of Los Angeles.
