Mysteries and Histories

In 1974, 28-year-old Karen Silkwood worked at Kerr-McGee’s plutonium fuel plant in Oklahoma. A union activist, she raised alarms about safety failures, radioactive contamination, and alleged falsification of quality-control records, then testified to the Atomic Energy Commission about the risks facing workers.
On November 13, she was driving to meet a New York Times reporter and a union official, reportedly carrying documents she believed could expose the company’s practices. She never arrived. Her car left Highway 74 near Crescent, Oklahoma, struck a concrete structure, and Silkwood was killed; the folder of documents she was said to be carrying was never found.
Investigators officially ruled it a single-car accident, concluding she may have fallen asleep at the wheel after taking prescription medication. But disputed physical evidence, the missing papers, and her prior plutonium contamination left enduring suspicions of foul play, suspicions that have never been proven. Her family later settled a lawsuit against Kerr-McGee for $1.38 million, with the company admitting no liability.

In March 2002, John Darwin paddled his canoe into the North Sea off Seaton Carew and disappeared. Searchers found wreckage, his family mourned, and his wife Anne claimed more than £500,000 in insurance and related payments. But Darwin had not drowned: he was alive, hiding in a bedsit next door to the family home while his two sons believed their father was dead.
Five years later, he walked into a London police station claiming he had amnesia. The story collapsed when investigators found a photograph of John and Anne together in Panama, taken while they were planning a new life abroad.
In 2008, both were convicted of fraud. John received six years and three months in prison, Anne six and a half years, after a deception that did not just target insurers, but shattered their own family.

In 1928, May Donoghue was drinking ginger beer at a café in Paisley when a friend poured the last of an opaque bottle into her glass. Out came the decomposed remains of a snail, something she could not have seen before drinking from it. She later became ill and sued the drink’s manufacturer, David Stevenson.
The problem was that May had not bought the drink herself, so she had no contract with the manufacturer. But in 1932, the House of Lords ruled that a maker of products owes consumers a duty to take reasonable care, even without a direct contract.
That decision, Donoghue v Stevenson, created the modern “duty of care” principle at the heart of negligence law. One alleged snail in one bottle of ginger beer changed consumer protection and personal-injury law around the world, although whether the snail was ever actually there was never proved in court.

In December 2010, 25-year-old landscape architect Joanna Yeates vanished after a night out in Clifton, Bristol. CCTV showed her buying a Tesco pizza on the way home but when detectives searched her flat, the pizza, its wrapping, and even the box were gone.
Her body was found on Christmas Day. The case initially fixated on her landlord, Christopher Jefferies, who was later cleared and formally acknowledged by police as completely innocent.
The real killer was Yeates’s next-door neighbour, Dutch engineer Vincent Tabak. Forensic evidence linked him to Joanna’s body, and prosecutors said he strangled her shortly after she arrived home before concealing and disposing of her body. He was convicted of murder in 2011 and sentenced to life imprisonment with a minimum term of 20 years.

In 1483, 12-year-old King Edward V and his nine-year-old brother, Richard, Duke of York, were placed in the Tower of London by their uncle, Richard, Duke of Gloucester, while Edward awaited his coronation. Instead, Richard took the crown as Richard III and the boys vanished from public view that summer, never to be seen alive again.
Most historians believe the princes were murdered, with Richard III long considered the likeliest person to have ordered it because their deaths removed the strongest rivals to his throne. But there is no conclusive contemporary proof, and competing theories remain.
In 1674, workmen found two child skeletons beneath a staircase in the Tower; they were later buried in Westminster Abbey as the princes’ presumed remains. Yet they have never been conclusively identified using modern forensic testing, so one of England’s most haunting royal mysteries remains unsolved.
