Local authorities have confirmed they have found the body believed to be Naya Rivera's and stars who shared their condolences on social media.
Bill Ayub from the Ventura County Sheriff's office said in a press conference today they are confident the body they found is Rivera's.
The body was found in a northeastern portion of Lake Piru, near the surface of the water.
Ayub said: "Based on the location where the body was found, physical characteristics of the body, clothing found on the body, and the physical condition of the body, as well as the absence of any other people reported missing in the area, we are confident the body we found is that of Naya Rivera."
He said according to work from detectives on the case there was "no indication of foul play and no indication this was a suicide".
Did she save her son?
Ayub said he believes Rivera managed to "muster" enough energy to push her son out of the water but couldn't save herself. Rivera's 4-year-old son was later found asleep on the boat she rented.
"We know from speaking with her son that he and Naya swam in the lake together at some point during their journey. It was during that time that her son described being helped into the boat by Naya who boosted him on to the deck from behind. He told investigators that he looked back and saw her disappear under the surface of the water.
"It would be speculation to say at this point. There are a lot of currents on the lake that appear particularly in the afternoon. We believe it was mid-afternoon when she disappeared, the idea perhaps being that the boat started drifting, it was unanchored, and that she mustered enough energy to get her son back on to the boat, but not enough to save herself."
He offered his condolences to Rivera's loved ones, friends, and family.
"As you can imagine it has been an extremely difficult time for the family throughout this ordeal.
"Our hearts also go out to Naya's friends and fans," the officer said during his statement to the media.
An autopsy will soon be carried out.
