Sheriff 'Confident' Body Found At Lake Piru Is 'Glee' Actress Naya Rivera

Authorities said they have every reason to believe the body found at California's Lake Piru this morning is that of missing "Glee" actress Naya Rivera, who is believed to have accidentally drowned. 

"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 ... we are confident the body we found is that of Naya Rivera," Ventura County Sheriff Bill Ayub said during a press conference Monday afternoon. 

He added that there was no indication of foul play or suicide. Investigators had previously said they believed Rivera had drowned in a tragic accident.

Rivera, 33, went missing on Wednesday during a boating trip with her 4-year-old son at Lake Piru in Ventura County. After nearly a week of searching, the Ventura County Sheriff's Office announced on Monday that a body has been located, but released no other information. 

"A body has been found at Lake Piru this morning. The recovery is in progress," the office wrote, announcing a press conference set to take place Monday afternoon — where Ayub revealed the body was Rivera.

Ayub said Rivera's was found in an area of the lake with deep waters and thick underwater vegetation. "As you can imagine this has been an extremely difficult time for her family throughout this ordeal ... our hearts are with them," Ayub said, adding that Rivera's family is aware of updates.

Rivera had rented a pontoon boat with her son, who was found sleeping alone on the boat Wednesday with no sign of Rivera. The boy later told investigators that Rivera lifted him onto the boat, but when he turned around she had disappeared, Ayub said during his press conference.

Officials have theorized that strong lake currents may have played a role in Rivera's death.

"The idea perhaps being that the boat started drifting ... and she had mustered enough energy to get her son back on the boat, but not enough to save herself," Ayub told reporters.

Authorities plan to conduct an autopsy at the Ventura County Medical Examiners Office to make a positive identification of Rivera's body through dental records, according to Ayub.
