California IN BRIEF : SAN DIEGO : Officer’s Killer Committed Suicide

An unemployed hospital worker who shot and killed a 24-year-old San Diego police officer Tuesday died after firing a single bullet into his head, the county medical examiner said. The death of Arnaldo Castillo, 34, was ruled a suicide after authorities determined that he shot himself with the same .45-caliber semiautomatic handgun he used to kill Ronald W. Davis, a two-year patrolman. Authorities originally believed that police had killed Castillo in a shootout following an 11-hour manhunt at a southeast San Diego apartment complex. But Homicide Lt. Dan Berglund said late Wednesday that none of the five shots fired by officers hit Castillo. The suspect was discovered by two teen-agers as he tried to hide between two cars. The youths pointed him out to a pair of television cameramen who notified police.
