Marvin Heemeyer bulldozed through the Liberty Savings Bank here along with 12 other buildings in Granby, CO, before he committed suicide.
Marvin John Heemeyer (October 28, 1951 – June 4, 2004) was a welder and an automobile muffler repair shop owner most known for his rampage with a modified bulldozer. Outraged over the outcome of a zoning dispute, he armored a Komatsu D355A bulldozer with layers of steel and concrete and used it on June 4, 2004, to demolish the town hall, the former mayor's house, and other buildings in Granby, Colorado. The rampage ended when the bulldozer got stuck in the basement of a building he had previously destroyed. Heemeyer then killed himself with a handgun.
