I'm Glad He's in Prison Now

Mark Winger is an Illinois nuclear engineer who was initially hailed as a hero in 1995 after claiming he shot and killed a shuttle driver, Roger Harrington, who had broken into his Springfield home and bludgeoned Winger's wife, Donnah, with a hammer. Police originally closed the case believing Harrington acted in retaliation over a previous customer complaint, allowing Winger to collect life insurance and marry his daughter's new nanny.
