Naya Rivera's cause of death revealed

'Glee' star Naya Rivera's cause of death has been confirmed as drowning and the manner of death is accident.

The Ventura County Medical Examiner has confirmed the identity of the body and has determined her cause of death to be drowning and the manner of death is accident.

"The autopsy findings are consistent with a drowning and the condition of the body is consistent with the time that she was submerged," the report obtained by some media outlets  stated.

 "No traumatic injuries or disease processes were identified at autopsy. There is no indication from the investigation or examination that drugs or alcohol played a role."

The 33-year-old actress went missing on July 8 while boating with her 4-year-old son Josey at California's Lake Piru.

 An investigation was launched to find Rivera after authorities found her son alone on a boat in the middle of the lake, which is located about 50 miles north of Los Angeles.

On Monday, July 13, the Ventura County Sheriff's department said that a body had been found at Lake Piru. Hours later, Ventura County Sheriff Bill Ayub said that authorities are "confident" that the body is Rivera's.

The body was discovered floating at the surface of the lake by personnel searching by boat early Monday morning.
