The Banker Who Robbed His Own Bank: Hudson’s Forgotten Heist
In 1864, Hudson, Michigan’s trusted bank president vanished with $60,000 and triggered a manhunt, jailbreak, and murder. This is the true story of William Treadwell—America’s original insider thief.
In the dead of night on January 21, 1864, the young president of the People’s Bank of Hudson quietly boarded a train and disappeared.
He took with him a black satchel—and more than $60,000 in cash.
William Treadwell wasn’t a thief in disguise. He didn’t smash a vault, carry a weapon, or wear a mask. He ran the bank. And for months, he’d been quietly planning to rob it from within.
His scheme would spiral into one of the most bizarre true-crime stories in Michigan history.
A Town That Trusted Him
Hudson was a quiet farming town near the Ohio line. During the Civil War, local townships and families deposited their money in the hands of young William Treadwell—an Oberlin graduate with a good marriage, a clean record, and a brand-new Italianate mansion under construction.
No one suspected he’d turn on them.
The Heist
In the weeks leading up to the crime, Treadwell sent letters to banks across the Midwest requesting loans. They replied with parcels of cash.
On January 21, with the vault full of public funds—tax payments, soldier wages, and widow pensions—Treadwell emptied the safe, changed the combination, and disappeared before sunrise.
By the time anyone realized what had happened, he was well out of Michigan.
The Chase
Authorities caught up with Treadwell three weeks later in Mansfield, Ohio. He was with his wife Mary and her father—but the satchel was gone.
In an audacious twist, while police arrested William, Mary and her father slipped away with the money. They were never charged.
Treadwell was returned to Michigan, tried, and convicted.
That very night, he broke out of jail with a cellmate.
The Betrayal
Treadwell’s escape partner was John Cowell, a drifter and horse thief.
The two fugitives headed south. But somewhere near Napoleon, Ohio, Cowell turned on him.
He shot William in the head, stole what remained of the money, and disappeared into the woods.
Weeks later, a farmer found the decomposing body in the brush. The face was unrecognizable. Only the banker’s satchel—and a few coins—remained.
Cowell was eventually captured, tried, and hanged in 1865.
What Happened to the Money?
Much of the stolen money was traced to Mary’s father, Samuel Hester. Civil suits dragged on for years. Some was recovered. Some vanished.
Treadwell’s grand mansion sat empty. He never lived to see it finished.
Mary remarried in 1866 and died not long after.
And Hudson, Michigan tried to forget.
