Actress disappears in the lake, her 4-year-old son is on his own.

Actress Naya Riveria is thought to have died today, while her 4-year-old son was found alone in a boat in California.

Glee's actress and son Josey rented a boat at Lake Piru on Wednesday afternoon, but 3 hours later another boat sounded the alarm after they saw a small child alone.

Police said they found Naya's life vest on the boat and that the actress was thrown into the lake to swim, but probably drowned.

The 33-year-old has participated in the Glee series from 2009 to 2015. Police and helicopters are looking for the actress's body.

From the statements of the little boy, the police learned that Naya had been thrown to swim and then had not returned.
