3 shot to death in Calif. neighborhood

A man shot his mother to death after an argument, then went next door and killed a neighbor woman and a 4-year-old girl, authorities said.

Two other children were critically wounded in the shooting Monday in this working class community east of Los Angeles.

"This was a tragic event in a quiet neighborhood," Baldwin Park police Capt. Michael Taylor said.

The Los Angeles sheriff's office said Tuesday that the suspect was in custody. His name and the names of the victims were not released.

Police were summoned to the scene about 7:30 p.m. When officers arrived, they found a man "standing in the street ... armed with a handgun," Sheriff's Lt. Daniel Rosenberg said. A search then led to the shooting victims.

"We believe the suspect who was detained got into some type of argument with his mother, shot and killed her, then went next door on some type of a shooting rampage and shot his neighbors," Rosenberg said.

The wounded, a 14-year-old boy and a 9-year-old girl, were taken to a hospital in critical condition, Rosenberg said.
