Body found at Lake Piru amid search for missing 'Glee' actress Naya Rivera

Rivera disappeared last week during a visit to the California lake with her 4-year-old son Josey.

Police confirmed Monday that they have found a body as the search for missing "Glee" actress Naya Rivera at a California lake continues.

Ventura police said in a tweet, "A body has been found at Lake Piru this morning. The recovery is in progress. A news conference will take place at 2 pm at the lake."

Authorities would not immediately say if the person found was Rivera, but said the day after she disappeared that they believed she drowned in the lake northwest of Los Angeles.

Rivera, 33, disappeared on July 8 during a visit to the California lake with her 4-year-old son Josey, who was found alone in a pontoon the actress had rented when authorities were notified.

Rivera had experience boating on the lake in Los Padres National Forest, authorities said. She is believed to have drowned “in what appears to be a tragic accident,” the statement said.

When the boat failed to return, its vendor found the vessel drifting in the northern end of the lake late Wednesday afternoon with the boy asleep on board. He told investigators that he and his mother had been swimming and he got back into the boat but she didn’t, according to a sheriff’s office statement.

The boy was wearing a life vest, and another life jacket was found in the boat along with Rivera’s purse and identification. Josey, the son of Rivera's ex-husband, actor Ryan Dorsey, is "in good health," authorities confirmed earlier in the week.

The couple finalized their divorce in June 2018 after nearly four years of marriage.
