Every year the Southwest Bank in Durango, Colorado hosts a Halloween costume party for employees and customers.

In 1997, an uninvited guest showed up. He and his sexy accomplice locked everyone in the vault and fled with more than $300,000 in cash.

Former pro baseball player, Craig Pritchert and Nova Guthrie, a pre-med student, used superglue, electronic voice changers and old-fashioned charm to pull off a string of bank robberies that baffled authorities across the south west of the United States.
