This week's episode of True Crime New England involves a case of a double murder with a side of some moral gray areas mixed in. Katie and Liz tell the story of the troubled and angsty Stephen Marshall, who grew up moving around the country and even to Canada, all while expressing his hatred for governmental structure and women. In April of 2006, Stephen decided to take justice into his own hands and become a vigilante killer, writing down the addresses of 29 sex offenders from the Maine State Sex Offender Registry. From here, he tracked down two men and shot them execution style, before fleeing on a bus to Boston. When the police showed up to arrest Stephen, he killed himself and took the answers to his heinous crimes with him.
