10 The Killings Took Place In The Same Area

The victims of the murderer were all discovered in or near the Whitechapel district of London, according to History.com. This area is located in the East End of the city.

Locals at the time were completely outraged and shocked by the details released about the murders.

What really stood out about the Ripper’s crimes was the sickening way in which the victims were treated. Many people still speculate that the murder had to have been a doctor or butcher, judging from the way the bodies were left.

The murder of Catherine Eddowes brought with it a clue that may have shed light on the identity of Jack the Ripper. Nearby her body, police found her bloodstained apron in the doorway of an apartment block. Above the apron, was a message written in chalk: "The Juwes are the men that will not be blamed for nothing."

Wanting to avoid racial tensions, the Metropolitan Police Commissioner, Sir Charles Warren, ordered the message to be erased rather than photographed and considered as evidence. According to the blog Jack the Ripper, this went against the wishes of the City of London Police, who felt that the message was an important clue.

1 New Genetic Tests May Have Finally Uncovered The Killer’s Identity

It’s been more than a century and we still don’t know the true identity of Jack the Ripper. But thanks to new genetic testing, some forensic scientists believe that they have finally uncovered the mystery.

A barber with access to knives, Kosminski was a prime suspect at the time. Science Mag points out that critics of this theory argue that the shawl could have been contaminated over time and these findings don’t necessarily mean that the case is closed.
