In the later half of 1888, London was terrorized by a sequence of murders in the east end mainly in the White chapel region. The name Jack the Ripper was in use from a letter sent to a newspaper at the occasion by someone claiming to be the murderer. The victims were characteristically prostitutes who had their throats cut and bodies mutilated. In some cases the bodies were exposed just minutes after the ripper had left the scene.
The police at the time had many suspects but could never find adequate evidence to convict anyone. In modern times there has even been some assumption that Prince Albert Victor was the killer. Even with modern police methods, no further light has been shed on the murders in current times. To this date no one knows who the ripper was.
