Glee star Naya Rivera could have hit her head diving from her boat into Lake Piry, claims diver - Daily Mail

Glee star Naya Rivera may have hit her head diving from her boat into a California lake, a diver searching for her body told DailyMailTV.

Search and rescue diver Robert Inglis said Rivera could have dived into the water from her boat and hit her head on one of the branches, shrubs and rocks beneath the surface of the Ventura reservoir that can be deceptively shallow.

The actress' four-year-old son was found alone in a rented boat on Lake Piru in Ventura on Wednesday evening with no sign of his mother.

During Friday's search, there were only 40 rescue personnel looking for Rivera.

Inglis said search teams from San Luis Obispo, Tulare and Los Angeles counties pitched in with the extensive three-day search that has so far yielded no results.

The 48-year-old search and rescue diver told DailyMailTV it's also possible Rivera, who was not wearing a life vest, got into difficulty swimming amid two-foot waves out on Lake Piru on a windy day.

Only 40 rescuers were at the scene looking for Rivera on Friday, a sharp contrast to the 100 that were at Lake Piru on Thursday.

He said it was possible Rivera hit her head on the submerged vegetation or hidden rock when diving into the water.  ?

The Ventura Sheriff's Department has released audio of the 911 call made on Wednesday by the boat rental facility at Lake Piru after an employee noted that Naya Rivera and her son had not returned

'On Wednesday when this began, some time around 1pm she came to the boat launch concession stand, rented a pontoon boat for a three-hour period,' he said

'The CCTV camera footage was also released and the video shows the boat going north

At 4.30pm they took one of their own boats and went out looking for her and they found the boat adrift with the son on board

On Thursday authorities released CCTV footage of the actress and her son arriving at Lake Piru and boarding their pontoon boat hours before she disappeared on Wednesday.  

Rivera was seen pulling up to the dock in her Mercedes-Benz SUV around 1pm on Wednesday, before hopping on a rental boat with the boy and heading out into the lake in the north direction. 

Along with the surveillance footage, cops have also shared the 911 call from the boat rental facility at 4.37pm when Rivera was first reported missing. 

The caller had apparently been sent to check on Rivera and her son after the actress failed to return the rental boat at the expected time.  

The pair climbed onto their pontoon boat rental before heading out into the lake at around 1pm
