TEMECULA, CALIFORNIA: A gunman opened fire at a Korean Christian retreat in Southern California Tuesday, killing one person and wounding three
others, authorities said.

The gunman was believed to be among the injured at the Kkottongnae Retreat Camp. Investigators were unsure what prompted the attack, sheriff’s spokesman Dennis Gutierrez said.

“We have some nuns that are very distraught,” Gutierrez added. He said at least two of the victims were critically injured. A nursing supervisor at the Inland Valley Regional Medical Center near the retreat said she had no information on any of the victims.

Police and emergency crews converged on the rural area off Highway 79 after receiving reports after 7 p.m. that a gunman had shot his wife, said Mario Lopez, a spokesman with the California Highway Patrol. He said one person was dead when they arrived and the other three were hospitalized.

Law enforcement officers interviewed people at what appeared to be a triage center for injured victims, but Gutierrez said the language barrier was making it difficult to get all the facts. He said investigators believe all the victims are over age 40.
