Marvin John Heemeyer spent months in seclusion after a series of defeats and judgements by the local government which took his business from him.
Suddenly June 4, 2004 he emerged with a bulldozer covered in metal plates and poured concrete and rampaged for the next 2 hours and 7 minutes he took on the entire police force, Colorado State Cops and an Earthmover and demolished the buildings of everyone that had wronged him before taking his life.
