4. Christophe Rocancourt
In 1991, French con artist Rocancourt began living in Los Angeles under various aliases. He even claimed to be the son of film producer Dino De Laurentiis and actress Sophia Loren. Managing to con some travel money, he next showed up in The Hamptons, New York, as “Christopher Rockefeller.” While in the Hamptons, Rocancourt convinced wealthy investors that he could double their money in as little as two weeks. He then fled to Canada, where he was eventually captured. He has served time in both Canada and Los Angeles.
