Authorities investigating the death of Glee actor Naya Rivera have said they think she may have drowned after "muster[ing] enough energy" to save her 4-year-old son, but "not herself".

Rivera disappeared during a boating trip last week, with authorities confirming on Monday night that her body had been found during their recovery mission on Lake Piru in California. She was 33.
After a search lasting five days, Ventura County Sheriff Bill Ayub confirmed on Monday night that a body had been found — and that authorities were "confident" it was Rivera's based on its condition and physical characteristics.

Ayub provided more information about the possible circumstances surrounding Rivera's death.
