A day after the body of actress Naya Rivera was found in Lake Piru, California, authorities also report the cause of death. Ventura County medical examiners said the cause of death of the Glee actress was accidental drowning.

"The autopsy findings are consistent with an autopsy. No traumatic injuries or disease processes were identified at autopsy. "There is no indication from the investigation that drugs or alcohol influenced the death, but these will be presented by the toxicology test," the BBC said in a press release.

Rivera, 33, lost track last week as he rented a boat on Lake Piru in California and sailed with his 4-year-old son, Josey. When the boat did not return after renting for three hours, staff found Josey in the boat wearing a life jacket. Another life jacket, believed to be for Naya, was still in the boat. On Monday, after several days of searching, the dead body of the actress was found. It was also said yesterday that Rivera may have died while trying to save his son .
