Unless it's been proven (not suggested or speculated) that he didn't kill any of the victims attributed to the BS, than he is the Boston Strangler. He seems to have killed at least 2 of the victims and no one else has been convicted of the other crimes. Perhaps you should reword to say he most likely didn't kill all the supposed BS victims as he claimed, but stating emphatically that he is not the Boston Strangler and that this has been proven is misleading.
