On July 8, the alarm was raised after the pontoon that Naya Rivera, 33, had rented for the afternoon failed to return to the dock in Lake Piru, California. A search ensued and the boat was located with Rivera’s four-year-old son, who was wearing a life jacket, alone on board. An adult life jacket and Rivera’s identification were also found on the boat.

Rivera’s son reportedly told investigators that his mother had helped him get on board before she disappeared beneath the water. Rivera was presumed dead on July 9 as the search and rescue mission converted to a recovery mission.

On July 13, The Ventura County Sheriff’s Office in California confirmed that they had located Rivera’s body.

Ventura County Sheriff Bill Ayub said during a press conference that there was no indication of foul play and no indication that Rivera's death was a suicide.

The day before she disappeared, Rivera shared this photo of her and her son on her Twitter:

Sheriff Ayub said Rivera "mustered enough energy to get her son back on the boat but not enough to save herself.”
