Corder's childhood thefts foreshadowed his later dishonesty
William Corder came from a wealthy farming family but had a history of theft and lies even as a child. He forged his father's name to borrow ten pounds and pocketed it. He privately sold the family's pigs and kept the money, forcing his parents to buy them back to settle a quarrel. These deceptions preceded his meeting Mariah Martin, establishing his character.
He stole child support money meant for his own child
Mariah Martin's child from a previous relationship with Peter Matthews was supported by monthly payments from the father. But the money often never arrived. Investigation revealed Corder was intercepting the payments at the post office and pocketing them. When confronted, he denied it, but postal clerks remembered him clearly—they noted his glasses and notorious poor eyesight. Corder persuaded Mariah to lie and corroborate his denials.
His remark about taking her clothes revealed her certain death
After her child died, Mariah disappeared six weeks later. But Corder told her family she was living elsewhere, waiting to be accepted as his bride. Then he made a chilling remark: Mariah's sister could take her clothes because she wouldn't need them anymore. In retrospect, this was nearly an outright admission that he had killed her.
The victim's stepmother's nightmares led to the body's discovery
Nearly a year after Mariah's disappearance, her stepmother Ann had repeated vivid nightmares in which Mariah had been murdered and buried in the Red Barn. Driven by these dreams, Mariah's father—a professional mole catcher—borrowed a rake from his neighbor and obtained permission from the barn owner to dig. Within eighteen inches, he found Mariah's shawl and human remains. Further digging uncovered her complete corpse, coat, hat, and shoes.
He advertised for a new wife while covering up the murder
Police searching Corder's residence near London found bundles of evidence: letters from friends warning him that the body had been discovered and urging him to escape; a gun and ammunition; and a new passport suggesting plans to flee continental Europe. Even more shockingly, he had already married a woman he'd known for only two months, having found her through matrimonial advertisements in newspapers—all while writing letters to Mariah's father claiming he and Mariah were living happily together on the Isle of Wight.
Ten murder charges covered all possible causes of death
The corpse had decomposed so severely that examining physician W. Wayman could identify only possible gunshot holes in the skull but could not determine the precise cause of death. To ensure conviction regardless of what evidence emerged at trial, prosecutors filed ten separate murder charges, each corresponding to a different possible method: shooting, stabbing, strangulation, and others. Under English law of 1836 and earlier, the accused had to present his own defense to the jury, not through a lawyer.
In court he claimed suicide; before execution he admitted to shooting
At trial, Corder claimed the two had quarreled in the barn and when he turned to leave, he heard a shot and found Mariah already dead—implying she had shot herself. The jury convicted him in only thirty-five minutes. But the night before his execution, he gave a completely different account: during their dispute over whether they would be discovered, they struggled; he drew a pistol from his pocket and fired. ‘She fell down, dead on the spot,’ he said.
— William CorderTwo centuries after his dissection, his bound skin finally surfaced
Between seven and ten thousand spectators attended Corder's execution. After his death, surgeon George Creed publicly dissected the corpse, displaying the muscles to the crowds. Five thousand more people queued to view the opened body inside a hall, during which Creed also conducted a phrenological examination. In 2025, when museum staff cataloged items donated by Creed's estate, they discovered two books whose covers had been bound from tanned human skin—Corder's skin—with the surgeon's handwritten notes inside explaining what they were.
