PITTSBURGH — The family of a neurologist who was fatally poisoned last year has filed a wrongful death suit against her husband, who was convicted of first-degree murder in her death. Attorney John Gismondi says the suit is being filed on behalf of Lois Klein, a Towson, Md. woman who is the mother of the victim, Dr. Autumn Klein. An Allegheny County jury convicted Dr. Robert Ferrante, who faces sentencing Feb. 4. The conviction carries an automatic life prison term.
