A man fatally shot his 5-year-old son and mother-in-law before turning the gun on himself near Los Angeles, police said. His wife was wounded in the shooting.
The Monday night shootings came about eight hours after Torrance police had served the man with a restraining order taken out by his wife.
Officer Dave Crespin said the man returned to the home after being served, then shot his son, wife, mother-in-law and himself. His son died at the scene and the older woman died at a hospital.
Police have not released the names of the gunman or the victims.
