The FBI says on February 2, the robber entered the bank and initially requested change, then handed the teller a threatening note. The robber also gave the teller a nylon case in which to put cash, which the teller did. The suspect then fled on foot to a nearby parking lot.
The "Hummer Bandit" is described as a white man, 40 years old, 5'10", heavy build, with dark hair, full sideburns and a mustache. He was wearing a baseball cap and sunglasses and was given the moniker "Hummer Bandit" due to the distinctive purple-colored Hummer SUV that he is believed to have used to escape.
