The Whitechapel murders were eleven unsolved brutal murders of women that were committed in the impoverished Whitechapel district in the East End of London, between 3 April 1888 and 13 February 1891.
Most, if not all, of the victimsâ€”Emma Elizabeth Smith, Martha Tabram, Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, Mary Jane Kelly, Rose Mylett, Alice McKenzie, Frances Coles, and an unidentified womanâ€”were prostitutes. Smith was sexually assaulted and robbed by a gang. Tabram was stabbed 39 times. Nichols, Chapman, Stride, Eddowes, Kelly, McKenzie and Coles had their throats cut. Eddowes and Stride were both killed on the same night, mere minutes and less than a mile apart, and the two murders were given the nickname the "double event". The bodies of Nichols, Chapman, Eddowes and Kelly had abdominal mutilations of increasing severity. Mylett was strangled. The body of the unidentified woman was dismembered, and the exact cause of her death is unclear.
Investigations were conducted by the Metropolitan Police Service, joined after the "double event" by the City of London Police. Private organisations, such as the Whitechapel Vigilance Committee, were also involved in the search for the killer or killers. Despite their efforts, and several arrests, the culprit or culprits evaded identification and capture. At various points some or all of the killings have been ascribed to the notorious, but elusive, individual known as Jack the Ripper.
