Elizabeth Stride
Unlike the other four Ripper victims, Stride had not been mutilated after her murder. For this reason,  some historians think Stride had not actually been murdered by Jack the Ripper. However, Stride's murder occurred less than one hour before the murder of the Ripper's fourth victim, Catherine Eddowes. The murder occured within walking distance. It is thought that the murderer was disturbed by someone entering the crime scene on a two-wheeled cart. In addition, both women had been murdered by slash wounds to the throat. For these reasons,  most authors and researchers consider Stride to be the third of the Ripper's five victims.
