We are opening one of history’s most enduring cold cases: the identity of Jack the Ripper and the string of brutal 1888 murders in Whitechapel. Our program dissects the new forensic evidence, traces the origins of the greatest conspiracy, and asks if modern science can truly close a 19th-century mystery plagued by contamination.

The latest claim that the case is solved centers on a bloodstained silk shawl from the Catherine Eddowes murder scene.

• The Scientific Claim: Researchers used PCR (Polymerase Chain Reaction) to amplify severely degraded mitochondrial DNA (mtDNA) from the shawl. They claimed a perfect mtDNA match to a descendant of victim Catherine Eddowes and a match to a descendant of suspect Aaron Kosminski, a Polish immigrant barber who worked in Whitechapel.

• The Suspect: Kosminski fits the profile: he had a documented history of severe mental health issues, auditory hallucinations, and homicidal tendencies. His profession, "barber surgeon," implied the anatomical knowledge used in the Ripper's precise mutilations.

• The Fatal Flaw: The scientific consensus holds serious reservations. Due to the 130-year-old broken chain of custody of the shawl, the potential for contamination is astronomical. mtDNA is not unique and can only confirm the fluid belonged to someone from Kosminski's maternal lineage, not definitively him. The lead scientists even conceded the evidence would not be conclusive in a modern court.

For over a century, the public preferred the spectacular conspiracy, which required no proof and appealed to cynicism about the ruling class:

• The Bisley Boy Conspiracy: Popularized by Stephen Knight’s 1976 book, the theory alleged that Prince Albert Victor (Queen Victoria’s grandson) was the killer, acting on the orders of the Prime Minister to cover up the Prince's secret marriage to a common law shop girl.

• Ironclad Debunking: This theory is a complete fabrication. The motive collapses because the marriage would have been legally void under the Royal Marriages Act of 1772. More importantly, Prince Albert Victor has airtight alibis, confirmed by official records that placed him 500 miles away in Scotland at Balmoral during the double murder. The logistics alone make him impossible to be the Ripper.

• The Masonic Theory: This intertwined theory, championed by Bruce Robinson, claims the murders were orchestrated by a Masonic cabal (doctors and police officers) to protect the establishment. This also collapses, as several key alleged conspirators are documented not to have been Freemasons.

The historical evidence shows the power of a captivating lie over complex reality. The question is why.

Final Question: The spectacular conspiracy—a royal plot shielded by a shadowy cabal—is tidy and dramatic. The likely truth is a mentally ill, impoverished Polish immigrant barber. Does our culture prefer the grand, exciting story of hidden powers over the likely messy and perhaps less dramatic truth?
