Rivera was reported missing last Wednesday after she and Josey, whom she shares with ex-husband Ryan Dorsey, visited Lake Piru to go boating and swimming.

Authorities said Monday that they believe Rivera died saving Josey.

"We know from speaking with her son, that he and Naya swam in the lake together at some point during their journey," Ventura County Sheriff Bill Ayub said at a news conference. "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 surface of the water."

"The idea perhaps being that the boat started drifting, it was unanchored, and that she mustered enough energy to get her son back onto the boat, but not enough to save herself," Ayub said.

Several former Glee cast members and other of former costars of Rivera's gathered at Lake Piru on Monday.

"Some of her cast members from Glee came to the lake and they were allowed to come down to the water's edge, and they, as a group, they prayed for her. And it was shortly after that, that her body was located," Ventura County Sheriff’s Office Sgt. Kevin Donoghue told PEOPLE earlier on Monday.
