The scientist who conducted a DNA analysis of the shawl found near the body of one of Jack The Ripper’s victims allegedly made a basic error, which means the identity of one of history’s most notorious killers is in doubt again.
At the beginning of September, armchair detective Russell Edwards declared that 23-year-old Polish immigrant, barber Aaron Kosminski, one of the suspects, was “definitely, categorically and absolutely” Jack The Ripper!
His statement came after genetic analysis of the shawl discovered near Catherine Eddowes, a victim of the notorious murderer, after alleged traces of semen were found there.
The scientist, Jari Louhelainen, who carried out the test, is reported to have made an “error of nomenclature” when using the DNA database to calculate the genetic match.
The alleged error was first spotted by crime enthusiasts in Australia posting on casebook.org. Then, the concerns were echoed by four experts in the field of DNA analysis, including renowned Professor Sir Alec Jeffreys, inventor of genetic fingerprinting.
The experts pointed out the error signifies no DNA link can exist between Kosminski and Eddowes, so any theory that Kosminski is The Ripper would be based on conjecture and supposition. Police at the end of 19th century, however, did have him as a suspect in the case.
All this comes in the wake of the publishing of the book ‘Naming Jack the Ripper’ by Russell Edwards, a businessman who purchased the shawl at an auction in 2007.
