A body has been recovered in the search for missing Glee actress Naya Rivera who vanished on a California lake and was feared to have drowned six days ago. Authorities are yet to formally confirm that the body is that of the 33-year-old. Rivera vanished on Wednesday on Lake Piru after taking a pontoon boat out on the water with her four-year-old son Josey. Josey was found alone, sleeping on the boat, by another group who noticed it drifting. Search and rescue teams have spent the last six days combing the lake for traces of the actress but struggled against poor visibility and the sheer size of the lake. On Monday, they honed in on a cove where the actress had taken a photograph of Josey and sent it to a relative 90 minutes before he was found on the boat. They focused their search on that cove on Monday. The actress grew up 20 miles from the lake and was familiar with it, police sources said last week. She thought of it as her 'sanctuary', despite it being known for rip currents and icy waters that can overpower swimmers. A press conference about Monday's discovery has been scheduled for 2pm local time.
