Rivera played Santana Lopez in the multiple Emmy and Golden Globe-acclaimed television series "Glee". Last Wednesday, Naya Rivera was out at sea with her four-year-old son.

Only the son remains in the boat

According to the son, who is said to be unharmed, they bathed together in the lake. Naya Rivera is said to have lifted her son into the boat, but then did not get up herself.

The son was still in the boat and a large search operation was launched. On Monday, police said Naya Rivera's body was found at Lake Piru, where they made the boat trip.

No illness or injury

The autopsy now shows that she died in a drowning accident and that neither alcohol nor drugs had anything to do with her death. There are no signs that she committed suicide or that she suddenly became ill or injured herself.
