Pictured here with his wife, Anne, John Darwin apparently drowned while canoeing in the North Sea in 2002. In reality, the Darwins were looking for a life insurance payout. In 2007, Darwin turned up in a London police station, pretending to have amnesia. Unfortunately for him, someone found a photo of the couple in Panama, where they were looking to buy property. The Darwins were sentenced to six years in prison for fraud and related charges. Anne ended up divorcing John and wrote a book about her experiences called Out of My Depth.
