DNA analysis claims to reveal identity of Jack the Ripper as Aaron Kosminski

A historian claims to have identified Jack the Ripper as Aaron Kosminski, a Polish immigrant, through DNA analysis of a shawl belonging to victim Catherine Eddowes. This marks a significant development after 137 years of speculation about the killer's identity. The shawl contained DNA from both Eddowes and Kosminski, who was known to have suffered from mental illness. The findings have sparked calls from victims' descendants for a formal investigation to legally confirm Kosminski as the killer. Skepticism remains regarding the DNA testing methods, as the research has not been published in a peer-reviewed journal. The UK Attorney General previously denied a request for a new inquest, citing insufficient evidence.
