Dempsey was indeed one of the prime suspects in the Boston Strangler deaths. Previously he had been charged with strangling an elderly woman four years prior and his killing method matched that of the Boston Strangler. Unfortunately due to internal infighting among detectives they failed to follow any potential leads and eventually lost track of Dempsey as an assailant.

He would often leave decorative bows tied around victims' necks as an added insult; additionally, their bodies would often be stripped down and posed to appear like domestic servants.
