Authorities say a Roman Catholic bishop in Southern California has been shot and killed just blocks from a church, stunning the Los Angeles religious community. The Los Angeles County Sheriff's Department says detectives are treating the death of Bishop David O'Connell as a homicide. Authorities have not said whether the bishop was targeted in the shooting. O'Connell was found suffering from a gunshot wound in Hacienda Heights, an unincorporated community about 20 miles east of downtown Los Angeles. Los Angeles Archbishop José H. Gomez confirmed the death. O’Connell was a priest and later a bishop in the city for 45 years.
