The Double Murder of Jo-Anne Muldoon and Deborah Johnson - Sept. 30, 1973

It's just before 9 p.m. on September 30, 1973. Jo-Anne Muldoon's parents arrive at her apartment on Intervale Road in Fitchburg after a call from a neighbor saying they could hear Jo-Anne's three month old son crying.   When they get to the second floor apartment, the door is unlocked. When the enter, the lights won't come on. The power in the apartment is out.   Using light from the flame of a cigarette lighter, the Muldoons find baby Christopher safe in his crib.   It would be their first and only sigh of relief.  They found their daughter's roommate Deborah Johnson dead on the sofa bed. In the kitchen, their daughter Jo-Anne was dead on the floor.  Both young women had been stabbed to death. Their throats had been cut.  More than 50 years later, their murders remain unsolved.
