Marvin John Heemeyer (October 28, 1951 -- June 4, 2004) was an American skilled welder and owner of an automobile muffler shop. On June 4, 2004, frustrated over a failed zoning dispute, Heemeyer plowed his homemade armored bulldozer into the town hall, a former mayor's home and other buildings in small-town Granby, Colorado. When the bulldozer's radiator and hydraulic system failed, he killed himself with a shotgun. Heemeyer used an armor-plated Komatsu D355A bulldozer to destroy 13 buildings in Granby, Colorado.
During the rampage, Mr Heemeyer actually had no intentions of murder, his primary motivation is to destroy all the properties of the companies or to the people who has opposed him in the past.
Today, all that remains of the 60-ton Komatsu bulldozer Marvin Heemeyer used to wreak havoc on Granby, Colorado is a dismantled engine, awaiting recycling in a scrap metal furnace. In the distance, the Rockies' timeless purple-gray peaks still frame Granby's majestic view, but for many residents the economic nightmare persists. Till today, the emotional and financial scars of that June day still remains.
