A recent genetic analysis has pointed to a compelling suspect in the Jack the Ripper murders\u2014using <strong>DNA evidence<\/strong> extracted from a 19th-century crime scene artefact.<\/p>\n\n\n\n<p>This breakthrough not only demonstrates the power of forensic genetics in <strong>solving historical mysteries<\/strong>, but also underscores the potential for DNA to reshape how we understand history, crime, and even our own ancestry.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The Case: A 130-Year-Old Cold Case Reopened<\/strong><\/h3>\n\n\n\n<p>Jack the Ripper&#8217;s grisly murders terrorised London\u2019s East End in 1888, and despite over a century of speculation, the killer\u2019s identity remained unknown\u2014until now.<\/p>\n\n\n\n<p>Researchers analysed <strong>mitochondrial DNA<\/strong> from a shawl said to belong to one of the Ripper\u2019s victims, Catherine Eddowes.
