1798 Bank of Pennsylvania heist

[2][3] Patrick Lyon, a blacksmith who had forged the vault doors and fitted the locks just weeks before the robbery, was initially a suspect in the heist.

[4] Lyon returned to Philadelphia to plead his case but he was imprisoned anyways; constable John Haines wanted to collect the $2,000 reward.

[1] Lyon spent three months in Walnut Street Jail, much of it in solitary confinement, where he did contract yellow fever and almost died.

[1][6][7] The sole perpetrators of the heist, Isaac Davis, a member of the Carpenters' Company, the guild that owned the building, and Thomas Cunningham, a porter at the bank, were later caught.

[1] Davis, who had visited Lyon's shop while he was forging the doors, aroused suspicion after depositing the stolen money in several banks, including the one he had burglarized, and he later confessed to the heist.
