DNA evidence unveiled during a forensic investigation in 2014 provides compelling support for Aaron Kosminski’s culpability in the Jack the Ripper case, adding a modern scientific perspective to this historic mystery. A shawl, reportedly found near the body of Catherine Eddowes, one of the Ripper’s victims, was analyzed.
