SAN DIEGO — Gov. Gavin Newsom on Wednesday ordered flags at the state Capitol to be flown at half-staff to honor the married San Diego police detectives who were killed by a wrong-way driver last week. Detective Jamie Huntley-Park, 33, and Detective Ryan Park, 32, died Friday morning when the driver of a wrong-way car on south Interstate 5 in San Ysidro slammed head on into their unmarked department sedan. The couple and the woman driving the other car — whose name officials have not yet released, but who has been identified in news reports — died at the scene. “Jennifer (Siebel Newsom) and I are deeply saddened by the tragic deaths of Detective Park and Detective Huntley-Park, a young married couple dedicated to public service,” Newsom said in a Wednesday statement. “Our thoughts go out to their loved ones, friends and their law enforcement family at the San Diego Police Department.”
