• DNA evidence on a shawl found at a Ripper murder scene nails the killer.
• By testing descendants of the victim and a suspect, identifications were made.
• Jack the Ripper has been identified as Polish-born Aaron Kosminski.
• Kosminski was a suspect when the Ripper murders took place in 1888.
• Hairdresser Kosminski lived in Whitechapel and was later put in an asylum.

GUILTY: A DNA sample has proven Polish immigrant Aaron Kosminski was Jack the Ripper

It is the greatest murder mystery of all time, a puzzle that has perplexed criminologists for more than a century and spawned books, films and myriad theories ranging from the plausible to the utterly bizarre.

But now, thanks to modern forensic science, The Mail on Sunday can exclusively reveal the true identity of Jack the Ripper, the serial killer responsible for  at least five grisly murders in Whitechapel in East London during the autumn of 1888.

DNA evidence has now  shown beyond reasonable doubt which one of six key suspects commonly cited in connection with the Ripper’s reign of terror was the actual killer – and we reveal his identity.

A shawl found by the body of Catherine Eddowes, one of the Ripper’s victims, has been analysed and found to contain DNA from her blood as well as DNA from the killer.

The landmark discovery was made after businessman Russell Edwards, 48, bought the shawl at auction and enlisted the help of Dr Jari Louhelainen, a world-renowned expert in analysing genetic evidence from historical crime scenes.

Using cutting-edge techniques, Dr Louhelainen was able to extract 126-year-old DNA from the material and compare it to DNA from descendants of Eddowes and the suspect, with both proving a perfect match.

The revelation puts an end to the fevered speculation over the Ripper’s identity which has lasted since his murderous rampage in the most impoverished and dangerous streets of London.

In the intervening century, a Jack the Ripper industry has grown up, prompting a dizzying array of more than 100 suspects, including Queen Victoria’s grandson – Prince Albert Victor, the Duke of Clarence – the post-Impressionist painter Walter Sickert, and the former Liberal Prime Minister William Gladstone.
