Tower Bridge in "Gentlemen of the Shade"Edit
Jack had been murdering prostitutes in the Whitechapel area, after drinking their blood. Though the member of the Sanguine Club accepted him at first, they were terrified that his actions would reveal them to the world.
After walking in at him disemboweling another prostitute, and disgusted at what they saw, the Club buried him alive in the Bridge as punishment.
