The Story of Marvin Heemeyer (KILLDOZER)

Disgruntled welder and muffler repair shop owner Marvin Heemeyer takes his armored Komatsu Bulldozer on a tour of destruction, demolishing the Granby town hall, the former mayor's house, and several other buildings and leaving millions of dollars in damage. The rampage comes to an end when he commits suicide, after his bulldozer becomes trapped in the basement of a partially-demolished hardware store.
