East Texas authorities have jailed an 18-year-old man on capital murder charges in the shooting of his parents, sister and brother.
Police in the small town of Nash, Texas said officers responding to a report that a man injured his family and threatened to kill himself on Tuesday found Cesar Olalde barricaded inside a home. They were told that several people had died inside.
Officers persuaded Olalde to turn themselves in and later found the bodies of his parents, Reuben Olalde and Aida Garcia, his older sister Lisbet Olalde and his younger brother Oliver Olalde in a bathroom.
