Teams are using sonar and robotic devices in what could be a long search for “Glee” star Naya Rivera, who authorities believe drowned in a Southern California lake. “We don’t know if she’s going to be found five minutes from now or five days from now,” Ventura County Sheriff's Capt.
Eric Buschow said at a news conference Friday, two days after Rivera's 4-year-old son was found asleep and alone on a boat the two had rented a few hours earlier.
Search teams on Lake Piru are towing sonar devices across the surface that scan the bottom for shapes that might be a body, then employing small remote controlled devices to explore the underwater spaces that show promise.
