What evidence was found in the time of the murders that could have incriminated Jack the Ripper?

Answer 1

The physical evidence in the Jack case, was evidence within the victims not a evidence surfaced against Jack the ripper since he was not aprended. Prostitutes were slashed and bloody letters were sent to the police.

Answer 2

It is an accepted fact that every killer leaves something of himself on the victim/crime scene and takes with him something of the victim's, be it blood, saliva, hair or minute fibers from clothes, sometimes even pet hair can connect killer to victim. I'm quite sure the Ripper left something of himself at each crime. But the science needed to catch this kind of killer did not exist. That left very little for police to work with. Eye witness testimony made up the biggest part of the investigation. Unfortuneatly, it is a proven fact that eye witnesses are the most unreliable type of evidence.

The few pieces of physical evidence found was little help to investigators on the case. The writing in chalk* at the Eddows scene was destroyed by Commissioner Charles Warren's order to wash it off the wall. There was also a piece of leather with blood stains found by a water spiget near Eddow's body. A clear attempt by the killer to wipe the blood from his hands, and then to wash his hands under the water spiget. The Whitechapel district was overflowing in butchers and furriers, and at times the blood actually flowed in the gutters along the streets. So a single piece of bloody leather did little to advance the investigation. In 1888 there was no test to determine human from animal blood. A piece of blood-soaked material was found nearby. It was found to match the apron Eddows was wearing at the time of her death. Without the forensic tools of the 21st century it remained just a piece of apron.

Answer 3

Scotland Yard investigated the Ripper murders with all available resorces. From undercover police walking the mean streets of Whitechapel to the searching of each home and boarding house, even tracking dogs were brought in, all with no resolution. Even the Queen was anxious to see the killer caught. The Ripper was causing quite a stir, drawing attention to the horrible living conditions in Whitechapel and Spitalfields districts.

Answer 4

At the time of the killings, modern techniques did not exists and back then there were none evidence that could have incrimanated Jack the ripper.

Answer 5

A leather apron soaked in blood would be a good evidence left at a crime scene in today's standards. It was not so good in those days. The ripper also send parts of the victim to the police.

Answer 6

He was never identified or caught although there are a couple suspects, never proven./
