CCTV: Naya Rivera boards boat before disappearance

Former "Glee" star Naya Rivera is presumed to have drowned while boating on a lake near Los Angeles, authorities said on Thursday (July 9).

The 911 call made to emergency services was also released. An unidentified woman reports a missing person.

"We've found a little girl in one of the boats by herself and the mom is nowhere to be found," she said referring to Rivera's son.

Rivera's four-year-old son was found alone and sleeping in a drifting boat on Wednesday (July 8) and told authorities they had both gone swimming but his mother never returned.

Officials said there was no indication of foul play but it was too soon to say what happened, or how long it might take to find Rivera's body.
