The Boston Strangler: Unheard Confession chronicles Casey Sherman’s renowned reinvestigation of the notorious 1960’s serial murder case, in which Sherman’s aunt, 19 year-old Mary Sullivan, a 1962 graduate of Barnstable High School, was believed to be the youngest and final victim. For the first time ever, viewers will hear the audio taped confession of self-proclaimed killer Albert DeSalvo, offering the raw and unfiltered account of the crimes that contradict the official story and raise new questions. This gripping two hour documentary casts fresh doubt and reignites the debate over the real identity of the infamous Boston Strangler.
