In New Hampshire,  the 22-year-old Judith Lord was strangled to death in her apartment in 1975.  

Police say her body was found with strangulation marks and signs of sexual assault. When they found her, they also found her 20-month-old son alive and unharmed in the room adjacent to hers. Evidence around the room pointed to a long and hard struggle between Lord and the murderer. 

When they came to take evidence, they had a strand of hair, but due to the analysis techniques of that time period, they were unable to match the hair to anyone. Years later, the suspect was identified as her neighbor, Ernest Theodore Gable, 50 years after the incident. They found him after more research and analysis of the fingerprints they had found at the time of the scene. 

Gable never got charged with murder because 13 years later, he was fatally stabbed. Police say if he were still alive, he would have been charged with first-degree murder.
