At around 3:30pm on May 30, 1984, seventeen-year-old nurse's aide and high school student Bernice Courtemanche left her home in West Claremont, New Hampshire.Her cause of death could not be determined. Two weeks later, on August 9, her body was discovered in a wooded area off Unity Stage Road in Unity, New Hampshire, about eighty miles from where she was last seen. She was last seen by a friend who dropped her off near exit 13 of the Massachusetts Turnpike. On July 25, 1981, thirty-seven-year-old college student Mary Elizabeth Critchley decided to hitchhike from Massachusetts to her home in Waterbury, Vermont.She had been stabbed over twenty times in the neck and abdomen. The next day, her body was found just yards from where she was last seen. On October 24, 1978, she left work and went to the Chandler Brook Wetland in New London, New Hampshire. The first victim was twenty-seven-year-old Cathy Millican.And police began to suspect that the killings were the work of the same individual. All of the victims suffered similar stab wounds. Police believe that six of the seven women were abducted and taken to remote, wooded areas, where they were murdered. Since 1978, the bodies of seven young women have been discovered within a fifty-mile radius in the Connecticut River Valley along the New Hampshire/Vermont border near Route 91. One such investigation is currently underway in New England. The overwhelming task for authorities is to determine how the serial killer thinks and hopefully learn where and when he might strike again. They are cruel and calculating, choosing victims indiscriminately, with little or no remorse for their actions. Details: Police estimate there may be as many as 100 serial killers living among us, on our streets and in our neighborhoods.
