Stephen Peter Morin (February 19, 1951 – March 13, 1985) was an American serial killer responsible for at least forty murders of young girls and women and 7 men in the 1970s and early 1980s. Since Morin led a transient lifestyle and constantly moved around the country, the exact number of his victims is uncertain, but he's suspected of a total 48 violent crimes across the USA. In the early 1980s, he was pursued by the federal authorities. The court found Morin sane and sentenced him to death by lethal injection. In 1985, he was executed at the Huntsville Unit.
