Stephen Peter Morin (February 19, 1951 – March 13, 1985) was an American serial killer who was suspected of being responsible for at least forty murders of young girls and women and 7 men in the period from 1969 to 1981. Since Morin led a transient lifestyle and constantly moved around the country, the exact number of his victims is uncertain, but he is suspected of a total 48 violent crimes across the United States. In the early 1980s, he was pursued by the federal authorities. Morin had created multiple aliases. These names included Rich Clark, Robert Fred Generoso, Thomas David Hones, Ray Constantino, and Constatine. The court found Morin sane and sentenced him to death by lethal injection. In 1985, he was executed by Texas after waiving his appeals.
