Authorities say that DNA taken from Albert DeSalvo's nephew is a near certain match to seminal fluid found in the home of Mary Sullivan, who was 19 when she was murdered in 1964, the New York Times reported Thursday.
According to the BBC, DeSalvo confessed to the murders but was never convicted. Instead, he spent life in prison for a series of armed robberies and sexual assaults.
Police will now exhume DeSalvo's body -- he was stabbed in prison in 1973 -- in the hope of conclusively linking him to Sullivan's murder.
Suffolk District Attorney Daniel F. Conley explained to reporters that while DeSalvo had confessed to the 11 murders and two others, his confession had "been the subject of scepticism and controversy from almost the moment it was given."
Despite the new evidence linking DeSalvo to Sullivan's murder, Conley said that too much time had passed to conclusively link him to all 11 murders.
“At this point in time, 50 years removed from those deaths and without the biological evidence that we have in the Sullivan case, that is a question that we cannot answer,’’ Conley said.
“But these developments give us a glimmer of hope that there can be one day finality, if not accountability, for the families of the ten other women murdered so cruelly in Boston, Cambridge, Lawrence, Lynn and Salem.’’
