The death of Glee actress Naya Rivera in a California lake last week was ruled an accidental drowning by medical examiners Tuesday. Rivera, 33, disappeared during a boating trip with her four-year-old son last Wednesday, and her body was found floating in Lake Piru on Monday. The Ventura County Medical Examiner’s Office formally confirmed Rivera’s identity using dental records, it said in a statement. No traumatic injuries or evidence of alcohol or other toxins were found.
