Actress Naya Rivera, who rose to fame on the TV show Glee, is missing and feared drowned, Ventura County authorities say. Rivera, 33, had rented a boat Wednesday on Lake Piru with her 4-year-old son, Josey Hollis Dorsey, but did not return it. The boat was found with her child aboard and unharmed, ABC7 reports, but she was not with him, and a later search of the water turned up empty. TMZ reports that the boy said his mother had jumped in the lake but had not reappeared. A search-and-rescue team will return to scour the lake Thursday.
