Marvin John Heemeyer (October 28, 1951 – June 4, 2004) was an automobile muffler repair shop owner who demolished numerous buildings with a modified bulldozer "KILLDOZER" in Granby, Colorado on June 4, 2004. Heemeyer had feuded with Granby town officials, particularly over fines for violating city health ordinances after local officials made it financially impossible for Heemeyer to connect to the city sewage system. He was subsequently fined for improperly dumping sewage from his business instead of connecting to the city sewer system. His feud came to a head on June 4, 2004. Over about eighteen months Heemeyer had secretly modified a Komatsu D355A bulldozer by adding layers of steel and concrete, intended to serve as armor. He used this to demolish the Granby town hall, the former mayor's house, and several other buildings. Heemeyer's rampage concluded with his suicide, after his bulldozer became trapped in the basement of a hardware store he had been in the process of destroying. #becomeungovernable #killdozer https://www.instagram.com/p/CPtHPayHXdH/?utm_medium=tumblr
