Jack the Ripper Victims

Case background and investigation

Between August 31 and November 9, 1888, at least five women were brutally murdered in the impoverished Whitechapel district of London's East End. The canonical five victims—Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly—were all killed by throat-slashing, and most exhibited escalating mutilations that suggested the killer possessed some anatomical knowledge. The murders terrorized Victorian London and spawned one of the largest police investigations of the era.

The Metropolitan Police, led by detectives Frederick Abberline, Henry Moore, and Walter Andrews, interviewed thousands of witnesses and investigated hundreds of suspects. The investigation was complicated by the poverty and transient nature of Whitechapel's population, the lack of forensic science, and intense media pressure. Letters received by police and newspapers, most famously the 'Dear Boss' letter and the 'From Hell' letter (which was accompanied by half a preserved human kidney), may or may not have been from the actual killer.

The identity of Jack the Ripper has been the subject of more than a century of speculation, with suspects ranging from local tradesmen and doctors to members of the royal family. Among the most frequently cited suspects are Montague John Druitt, a barrister who drowned shortly after the last murder; Aaron Kosminski, a Polish immigrant; Michael Ostrog, a Russian con man; and Prince Albert Victor, Duke of Clarence. DNA analysis conducted in the 2010s produced inconclusive results, and no suspect has ever been definitively linked to the crimes.

The case essentially defined the concept of the serial killer in the public imagination and continues to generate books, films, walking tours, and academic studies. The Whitechapel murders file was officially closed in 1892, but the case has never been solved. It remains the most famous unsolved serial murder case in history.
