Jean-Claude Romand

For 18 years a Frenchman named Jean-Claude Romand convinced his family and friends that he was a successful medical doctor at the World Health Organization. Instead of working, he hid in hotels to study medicine and maps of countries he claimed to visit. He lived off the money his wife and he had made by selling an apartment, from his wife's salary, and from sums of money which were given to him by various relatives, who relied on his assurances that he was investing the money in various imaginary hedge funds and foreign ventures. When he feared that he was going to be exposed, he killed his wife, his two children, his parents, their family dog and also tried to kill his ex-mistress. Then he burned down his house.
