SEE IT: CCTV footage shows missing actress Naya Rivera and 4-year-old son boarding boat hours before she disappeared

Authorities in Ventura County have also released the 911 call first reporting the discovery of Rivera’s young child alone on a boat

Authorities in Ventura County, California, have released video and audio recordings connected to the disappearance of “Glee” actress Naya Rivera, who is presumed drowned after she did not return from an outing on a rented pontoon boat with her 4-year-old son.

As CrimeOnline previously reported, a fellow boater found Rivera’s son alone and asleep in the drifting boat at Lake Piru in Ventura, California, late afternoon or early evening Wednesday.

The boy reportedly told police that he and his mother had gone swimming but that she did not return to the boat. The boy was found wearing a life vest and an adult life preserver had been left behind on the vessel.

The Sun obtained audio of a 911 call reporting the discovery of the child on the boat. The caller tells the dispatcher that they were not at the scene themselves when the child was found, and could not answer many questions. At the time, the caller believed that the child was a little girl and said they were on their way to the scene. The 911 dispatcher told the caller to call back when they had arrived and had more information, but the Ventura County Sheriff’s Office did not release a follow-up call.

The CCTV video, which appears to have been sped up and has been shared by multiple news outlets, reportedly shows Rivera and her son pull into the parking lot of where boats are docked and then walk to the boat, where they are assisted by someone, presumably a worker, before they leave the dock.

CNN reports that the search for the missing actress is expected to resume Friday morning.
