Nearly five decades after the last Boston Strangler murder went unsolved, police say they can now prove who the murderer was, even though the prime suspect has been dead for 40 years. The case of one of the nation's most notorious serial killers dates back to 1962 when the first of 11 women were murdered in the Boston area. Nearly all the victims were sexually assaulted and then strangled with their own stockings, with the last killing taking place in 1964.
Later in 1964, a man named Albert DeSalvo was arrested on an unrelated sexual assault charge and he confessed to the killing. However, there was no physical evidence tying him to any of the crimes and the confession was ruled inadmissible in court. He was sentenced to life in prison on the other crimes, but the Boston Strangler crimes remained officially unsolved.
DeSlavo was murdered in prison in 1973, but that did not end the fascination with the case or the determination to solve it. Now police say they have the physical proof they've been looking for all along — thanks, of course, to modern DNA technology. Police announced on Thursday that they are "in a position" to charge DeSalvo with the murder of Mary Sullivan, who was the final victim in 1964.
