Authorities said Thursday that they believe ``Glee'' star Naya Rivera drowned in a Southern California lake but they are continuing to search for her.
Ventura County Sheriff's Sgt. Kevin Donoghue said Thursday there is no sign Rivera ever left the waters of Lake Piru, where her 4 year old son was found alone on a boat they had rented a day earlier.
He said the search has shifted from an attempt to rescue Rivera to an attempt to recover the the 33 year old's body.
Donoghue says surveillance video shows mother and son leaving the dock together.
He said Rivera had experience taking boats on the lake.
