DNA evidence has uncovered the identity of Jack The Ripper, and it’s none of the romantic suspects – such as the Queen’s surgeon Sir William Gull, or artist Walter Sickert.

The most infamous serial killer in history has been identified as a relatively underwhelming Polish madman called Aaron Kosminski, who was committed to a mental asylum at the height of the Ripper hysteria.

Kosminski was actually a suspect at the time of the murders, even named by Chief Inspector Donald Swanson in notes the policemen made, but as the myth and legend of the murders grew over more than 125 years, so too did the list of more fanciful suspects.

The breakthrough came when a scientist, using cutting-edge technology, matched DNA evidence on a shawl found at one of the crime scenes with descendants of Kosminski.

Dr Jari Louhelainen, a Finnish expert in historic DNA, was brought in to study a shawl found with Mary Eddowes, the second-last ‘confirmed’ victim of the Ripper, whose body was discovered in Mitre Square on September 30.

The shawl – still retaining stains and genetic material from the fateful night almost 126 years ago – had been bought by businessman Russell Edwards, 48, at an auction in Bury St Edmunds in 2007.

In the Mail On Sunday, Dr Louhelainen is quoted as saying: ‘It has taken a great deal of hard work, using cutting-edge scientific techniques which would not have been possible five years ago.

‘Once I had the profile, I could compare it to that of the female descendant of Kosminski’s sister, who had given us a sample of her DNA swabbed from inside her mouth.

‘The first strand of DNA showed a 99.2 per cent match, as the analysis instrument could not determine the sequence of the missing 0.8 per cent fragment of DNA. On testing the second strand, we achieved a perfect 100 per cent match.’

Aaron Kosminski was born in the Polish town of Kłodawa, then part of the Russian Empire, in 1865. He emigrated to England with his family in 1881, moving to Whitechapel.

It is clear that he was suffering psychological problems, with latter-day case notes saying he had been ill from 1885.

The murders attributed to Jack The Ripper began in 1888. Anywhere between five and 11 murders of women in and around the Whitechapel area have been linked to the Ripper.

The five relatively undisputed murders – of Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes and Mary Jane Kelly – happened between August 31 and November 9 1888. The 126th anniversary of Chapman’s murder is on Monday (September 8).

The police file on the murders also point to the mutilation deaths of Rose Mylett, Alice McKenzie, the ‘Pinchin Street torso’ and Frances Coles – Coles being the last to die in February 1891.

In February 1891, Kosminski was forcibly put in Colney Hatch Lunatic Asylum, and he remained in asylums until his death in 1919, aged 53.
