Marvin Heemeyer was born on October 28, 1951, on a dairy farm in South Dakota. No one else was injured or killed, in part due to timely evacuation orders. He killed himself after the bulldozer got stuck in a hardware store he was destroying. On Friday, June 4, 2004, Heemeyer used the bulldozer to demolish the Granby town hall, the house of a former mayor, and several other buildings. Over about eighteen months, Heemeyer had secretly armored a Komatsu D355A bulldozer with layers of steel and concrete. Heemeyer had various grudges against Granby town officials, neighbors of his muffler shop, the local press and various other citizens of Granby. Marvin John Heemeyer (Octo– June 4, 2004) was an American automobile muffler repair shop owner who demolished numerous buildings with a modified bulldozer in Granby, Colorado, before killing himself during the attack after being confronted by law enforcement.
