The Goulston Street graffito was a sentence written on a wall beside a clue in the 1888 Whitechapel murders investigation. It has been transcribed as variations on the sentence "The Juwes are the men that will not be blamed for nothing". The meaning of the graffito, and its possible connection to the crimes attributed to Jack the Ripper, have been debated for over a century.
The Whitechapel murders were a series of brutal attacks on women in the Whitechapel district in the East End of London that occurred between 1888 and 1891. Five of the murders are generally attributed to "Jack the Ripper", whose identity remains unknown, while the perpetrator(s) of the remaining six cannot be verified or are disputed.
After the murders of Elizabeth Stride and Catherine Eddowes during the night of 30 September 1888, police searched the area near the crime scenes in an effort to locate a suspect, witnesses or evidence. At about 3:00 a.m., Constable Alfred Long of the Metropolitan Police Force discovered a dirty, bloodstained piece of an apron in the stairwell of a tenement, 108 to 119 Model dwellings, Goulston Street, Whitechapel.
The cloth was later confirmed as being a part of the apron worn by Catherine Eddowes. Above it, there was writing in white chalk on either the wall or the black brick jamb of the entranceway.
