Handyman Albert DeSalvo confessed to eleven brutal rape/murders that terrorized Boston from 1962 to 1964. The repeat sex offender boasted he had raped an additional 2,000 women. His story became the subject of a bestselling book, a major Hollywood movie, and a Hulu docuseries. But DeSalvo was not The Boston Strangler. Author Susan Kelly's detailed investigation shows us the true DeSalvo - a pathological liar whose hunger for celebrity drove him to false confessions - and indicates that the stranglings were committed by more than one killer. Exploring stunning DNA findings, a shocking re-autopsy, expert profiling evidence, and other recent developments, she shows why this savage, unsolved case continues to fascinate and haunt us.
