within the museum. The alleged DNA match was based on one of seven small segments taken from the hypervariable regions within the DNA. The segment contained a sequence variation described as 314.1C, and claimed to be uncommon, with a frequency of only one in 290,000 worldwide. However, Professor Sir Alec Jeffreys and others pointed out this was in fact an error in nomenclature for the common sequence variation 315.1C, which is present in more than 99% of the sequences in the EMPOP database. The owner of the shawl, British author and amateur sleuth Russell Edwards, has since claimed these forensic results prove Kosminski was Jack the Ripper. He is quoted as saying: "Seven years after I bought the shawl, we had nailed Aaron Kosminski." However, other experts strongly disagree. Donald Rumbelow criticized Edwards' claims, saying that no shawl is listed among Eddowes's personal effects by the police, and that the policeman who allegedly retrieved the garment was based in North London in 1888, thus making him unlikely to have been present at any of the crime scenes. Archaeological geneticists have also stated the forensic techniques utilised in reaching this conclusion are neither new nor scientifically accurate. Mitochondrial DNA expert Peter Gill has also stated the shawl "is of dubious origin and has been handled by several people who could have shared that mitochondrial DNA profile." Two of Eddowes's descendants are also known to have been in the same room as the shawl for three days shortly after Edwards had purchased the garment in 2007. In the words of one critic, "The shawl has been openly handled by loads of people and been touched, breathed on, spat upon. My DNA is probably on there. What's more, Kosminski is likely to have frequented prostitutes in the East End of London. ... If I examined that shawl, I'd probably find links to 150 other men from the area."
