"Glee" Actress Naya Rivera Missing At A Lake In Southern California

Southern California police are searching for actress Naya Rivera, best known for her role as Santana Lopez on Glee, after she was reported missing from Lake Piru in Ventura County.

Rivera had rented a boat on the lake with her four-year-old son Wednesday afternoon. Wednesday evening, a boater discovered the boat adrift with the son asleep on board and Rivera nowhere to be found.

Ventura Country Sheriff's Capt. Eric Buschow stated the child told officials the pair went swimming but Rivera didn't get back on the boat. The child was wearing a life-jacket and there was an adult life-jacket on board.

A search began immediately Wednesday evening and resumed this morning. "We hope for the best, we prepare for the worst," said Ventura County Deputy Chris Dyer in a press conference.

This morning, TMZ reported that the search had changed from a "rescue" mission to a "recovery" mission, indicating police believe that Rivera has drowned.

Her disappearance quickly became a trending topic on Twitter, with many furious at officials for pausing the search overnight.

Rivera shares custody of her son with her ex-husband Ryan Dorsey.
