WorldViews: Author claims to have identified Jack the Ripper via DNA testing of a shawl

In the end, it may have takena Johnny Depp movie, a shawl and a DNA testto solvethe mystery behind one of the most notorious serial killing sprees in London: Who was Jack the Ripper?

British businessman and noted "Ripperologist" Russell Edwards claims to havefinally and conclusively identified the serial killer asAaronKosminski, a Polish immigrant and barber.

Edwards unmasked his candidate for Jack the Ripper in the Daily Mail and chronicles how he came to the conclusion in a forthcoming book.

Kosminski has long been one of the more credible suspectsin thefivegruesome murders of women in the London's East End in 1888. Born in central Poland on Sept. 11, 1865, he moved with his family movedto east London in the early 1880s, and lived near the murder scenes, according to Agence France Presse.

He ended up in a workhouse the year after the murders and was described as destitute; a year later, he was discharged but eventually ended up in an insane asylum -- he was thought to have been "seriously mentally ill," Edwards writes -- where he died from gangrene in 1919. A witness had identified Kosminski as the murderer at the time.

Edwards said his interest in Jack the Ripper began after he watched"From Hell," a2001 film about the murders that starred Depp as a clairvoyant police inspector.

In 2007, Edwards bought a shawl thathad been discovered at the scene of the murder of Catherine Eddowes, the fourth Ripper victim. Before Edwards bought it, the shawl belonged to the relative of a police official who had been allowed to take it home to his dressmaker wife, Edwards writes. "Incredibly, it was stowed without ever being washed," and handed down in the family, he said.

When Edwards bought the shawl, he subjected it to DNA testing, which confirmed that the blood on it belonged to Eddowes. A UV light showed semen on the fabric. That DNA was compared to that of a Kosminski descendant, Edwards writes.

The identity of Jack the Ripper haseluded Brits for over a century and obsessedeveryone from serious academics to armchair detectives. Queen Victoria's grandson Prince Albert Victor was thought to be a suspectat one point, but it turned out he wasn't near the murders at the time. Other suspects have includedMary Pearcey ("Jill the Ripper"), who had been convicted of murdering her lover's wife; in 2006, an Australian scientist, pointing to DNA results, suggested the killer may have been a woman.

Historian Mei Trow had previously identified mortuary attendant Robert Mann as Jack the Ripper, using "psychological and geographical profiling," the Daily Mail wrote in 2009.The murdervictims' bodies would have been delivered to the mortuary where Mann worked, where he was suspected to have "admire[d] his handiwork."
