Between August and November 1888 in London's Whitechapel area, five brutal murders of prostitutes were committed. The victims - Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly - became known as the "Canonical Five" victims of Jack the Ripper. The killer's modus operandi involved throat slashing and abdominal mutilation. Despite an extensive investigation involving over 2,000 interviews, the identity of Jack the Ripper was never discovered. The case remains an unsolved mystery.
