LANCASTER, Calif. (AP) — Authorities say four children including an infant and their grandmother have been found shot to death in a Southern California home and that the children’s father was arrested on suspicion of killing them. Police say the children’s mother found the bodies Sunday night in the city of Lancaster in the high desert Antelope Valley north of Los Angeles. The Los Angeles County Sheriff’s Department says the grandmother, a girl and three boys, all under age 12, suffered gunshot wounds to the upper torso. The children’s father, 29-year-old Germarcus David, turned himself in at a sheriff’s station and was arrested minutes after the mother arrived home.
