The Boston Strangler case is back in the headlines with the news that DNA from the 1964 murder case of Mary Sullivan has been definitively linked to Albert DeSalvo, who had confessed to the crimes but was never convicted. Boston College History Professor Alan Rogers is the author of The Boston Strangler (Commonwealth Editions, 2006), part of the New England Remembers book series, which gives an overview of the serial killings that terrorized Boston in the early 1960s, and the evidence that pointed to DeSalvo as the killer. Rogers says this new DNA testing provides the obvious answer to the age-old question: Was Albert DeSalvo the Boston Strangler? “There’s not a shred of evidence pointing to anyone else. The preponderance of evidence in the case was so overwhelming. DeSalvo recalled details in each and every slaying that no one else could have known. These details weren’t in the newspapers but he knew them.”
