The Harpe Brothers: America’s First Serial Killers

Did You Know that America’s first known serial killers weren’t operating in the shadows of a modern city, but on the wild frontiers of the 18th century? 

Meet Micajah and Wiley Harpe—two men so brutal, even their fellow outlaws were terrified of them. Known as Big Harpe and Little Harpe, these two left a trail of death and fear across Kentucky and Tennessee during the early years of the United States.

The Harpes were born in the 1760s, likely in North Carolina, to Scottish immigrant families. Though they were cousins, they often referred to each other as brothers. During the American Revolutionary War, they fought not for the colonists, but for the British, aligning themselves with Loyalist raiders known as the Tories. It was during this time that they reportedly participated in looting, pillaging, and violence against patriot families.

When the war ended in 1783, the Harpes didn’t give up their violent ways—they simply redirected them. Rather than return to a peaceful life, they took to the lawless American frontier, where early settlements had little or no formal law enforcement. For men like the Harpes, this was the perfect environment to indulge their bloodlust.
They joined up with a gang of river pirates along the Mississippi, robbing flatboats and murdering travelers. By the 1790s, the Harpes had become infamous along the frontier, not just for their criminal activities, but for their astonishing cruelty. Unlike most outlaws who killed for money or revenge, the Harpes seemed to kill purely for the thrill.
They traveled with three women—two of whom were reportedly kidnapped—and a growing group of children. It’s said that Big Harpe murdered his own infant child for crying too loudly, slamming the baby against a tree. This horrifying act shocked even fellow criminals and sparked widespread revulsion.
Their known murder spree began in earnest around 1797, spanning Tennessee and Kentucky. They posed as weary travelers or preachers, gaining the trust of strangers. Then, without warning, they’d slaughter their victims, often mutilating the bodies afterward. Throats were slashed, limbs severed, and torsos split open. Big Harpe had a signature method of execution—he would gut his victims and fill the body cavity with stones, then sink them into rivers to conceal the evidence.
In one especially heinous incident, they killed a man named Johnson, whose corpse was found disemboweled and stuffed with rocks. Another victim, a young boy, was butchered for no apparent reason while out in the woods. These were not crimes of passion or self-defense—they were calculated, cold-blooded murders.
What set the Harpes apart from other violent men of their era was the randomness of their killing. They murdered travelers, innkeepers, farmers, and even children. Sometimes they stole from their victims, but just as often they left valuables behind, suggesting the motive wasn’t robbery—it was bloodlust.
As the death toll climbed, the public outcry reached a boiling point. Posses were formed to track the brothers down. In 1799, their rampage came to an end when a group led by Moses Stegall—whose wife and child had just been murdered by the Harpes—caught up with them near Henderson, Kentucky. Big Harpe was shot, captured, and reportedly confessed to over twenty murders before dying. His final request was for water, which Stegall denied. Harpe’s decapitated head was later mounted on a tree as a warning to others. That site became known as Harpe’s Head Road—a grim reminder of his legacy.
Little Harpe managed to escape, blending in with the very criminal underworld that had once feared him. Years later, he joined the infamous river pirate Samuel Mason, but his luck ran out. He was eventually captured, identified, and executed in 1804. Like his cousin, his head was also displayed publicly.
Despite the horror of their crimes, the Harpe Brothers are rarely mentioned in mainstream
