Tabram, most likely MacKenzie - and all the Thames torso victims.
Because I think Tabram was likely a Ripper deed, because I think MacKenzie was likely a Ripper deed - and because I think there can be no serious doubt that the Ripper and the Torso killer were one and the same.
I agree Alice McKenzie has a great possibility of being killed by the same hand as some of the other victims in this case. I disagree her killer was left handed. The evidence points more toward a right handed killer. I am surprised Dr. Phillips said the wounds were made by a left handed person. Dr. Bond also disagreed with him on that point.
