Dr. Jean-Claude Romand, in France, was a renowned doctor or medicine, working for WHO organisation in Switzerland, travelling extensively to attend specialised medical conferences. He had an attractive wife and two lovely young children, 5 and 7. One days, he murdered his wife, then shot his 2 children, went downstairs to watch TV. The next day, he went to have lunch with his elderly parents, shot both of them. In the evening, he tried to strangle a dear female friend while going to a dinner party. He then went home, swallowed some pills, set fire to his house. When the firemen arrived, he was still alive, while his little family was dead and charred. Investigators soon found out that for 20 years, he had lied to his wife, parents, children, friends, and relatives. He never graduated from medical school. He pretended to drive to work each morning, but he was spending his days in libraries and hotels. He paid his bills by using the money his relatives and his parents told him to invest at a high interest rate--- or so he said. But when Pierre Crolet, his father-in-law asked Romand for his money back, he was soon found dead--- fell down the stairs. When his lady friend asked Romand to repay her money, he tried to strangle her. Soon his lies were going to be uncovered, so he decided to murder everybody. This episode of L&O is inspired by Dr. Romand, who is still alive, serving a lifetime jail sentence, and never expressed any regrets or remorse.
