Yesterday, we reported that police had tragically found the body of former “Glee” actress Naya Rivera five days after she went missing while boating on Lake Piru in California with her 4 year-old son. Now, details about Rivera’s final moments before she drowned in the lake have been revealed.

The U.K. Mirror reported that during a press conference after her body was found, Sheriff Bill Ayub explained that Rivera, 33, and her son Josey had gone for a swim that fateful Wednesday afternoon.

“We know from speaking with her son that he and Naya swam in the lake together at some point during their journey,” Ayub told reporters. “It was during that time that her son described being helped into the boat by Naya – who boosted him onto the deck from behind. He told investigators that he looked back and saw her disappear under the water.”

Three hours after Rivera and her son got on their pontoon, it was found floating with Josey sleeping on the vessel alone. He was wearing a life vest, and another adult-sized life vest was found on the vessel as well, but Rivera was nowhere to be found.

“Naya’s son was later found asleep on the boat which was adrift in the northern portion of the lake, known as ‘The Narrows,’ when a leasing agent searched for the water craft which was overdue for return,” Ayub said. “The young boy was wearing a life vest when he was found and he was wrapped in a towel. An adult-sized life vest was found on the boat.”

“She must have mustered enough energy to get her son back on the boat, but not enough to save herself,” he continued.
