Naya Rivera is presumed dead after going missing, with her four-year-old son being found alone floating on a boat on Lake Piru in Ventura County, California.
Captain Eric Buschow, a spokesman for Ventura County Sheriff's Department, said they responded to a report of the toddler alone on a boat around 4.48pm on Wednesday.
