Remember Killdozer Day. On June 4, 2004, Marvin Heemeyer, who’s business, finances and property values were destroyed by an unethical local government, mobilized with his modified bulldozer. He made several targeted attacks against buildings and businesses in the city: his own business, the concrete plant, a local newspaper office, the town hall, a former mayor’s house, and a hardware store. Each of these locations had, in some way, been instrumental in his troubles with the city or in previous lawsuits.
