Einhorn was found guilty of fatally bludgeoning his girlfriend, Helen “Holly” Maddux, 30, in 1977 and stuffing her body into a trunk that he kept in his Powelton apartment for 18 months. In 1981, just before his trial, he fled to Europe, and he remained on the lam for two decades. He was extradited from France in 2001, and a Philadelphia jury convicted him of first-degree murder in 2002 in Maddux’s slaying. He was sentenced to life in prison.
