7 Things You Didn’t Know About Marvin Heemeyer’s Killdozer Revenge  

One can never know how far people can go in anger until they are pushed. Marvin Heemeyer felt pushed and he went farther than anyone would have thought. He made it to the headlines when he decided to give to his community what he thought they deserved – the Marvin Heemeyer’s Killdozer Revenge.

After 3 years of legally trying to stop the zoning of land that would both hinder him from taking the easy route to his muffler shop and destroy the business that took him years to build, he decided it was time to take revenge on Granby, Colorado. He then redesigned a bulldozer into a D355A Killdozer that he used to pass through many walls and destroyed properties worth about $7 million dollars.

Although many described him to be a hardworking and logical man who owned an automobile muffler shop, Marvin Heemeyer’s revenge on Granby has been described as unreasonable. Heemeyer, however, felt that ‘sometimes reasonable men must do unreasonable things’.

Facts About Marvin Heemeyer’s Killdozer Revenge  

1. What Led to the Killdozer Revenge?

Although he was born in South Dakota, United States, Marvin Heemeyer moved to Granby 10 years before the revenge and started a shop as a welder; he owned an automobile muffler repair shop. His business flourished quite well thanks to the work and dedication he put into it. In 1992, he bought a piece of land and built his muffler shop on it. Subsequently, he planned on selling the land to Cody Docheff to build a concrete batch plant, but because they couldn’t agree on the fee, Docheff backed out.

Fate had its way when the zoning commission and the town’s trustees later ratified the construction of a concrete batch plant on the land next to his. The problem was that it was a shortcut he used between his shop and home. With all efforts to get the zoning commission to reconsider its stance failing, he decided he was going to get his revenge.

2. How He Created his Killdozer

Following his dispute with the Granby zoning commission and his inability to get what he wanted, Heemeyer decided to make a statement using a bulldozer he initially purchased with the aim of creating an alternative route from his home to his shop.

He modified the bulldozer into an indestructible monster that would later be named a “Killdozer”. The bulldozer had a makeshift armor plating covering the cabin and other parts of the machine; bulletproof cameras, 5000-PSI Quikrete concrete mix sandwiched between the sheets of tool steel which he used to make an ad-hoc composite amour that made the Killdozer impenetrable to bullets and explosives.

3. When did Marvin Heemeyer Carry out His Revenge?

For 18 months, Heemeyer built his Killdozer, but before the revenge, he made several audios and notes stating his reasons for the attack. In his note he wrote, “I was always willing to be reasonable until I had to be unreasonable”. He sent the audios to his brother hours before executing his plan.

On June 4, 2004, in Granby, Colorado, Marvin at the age of 54 decided to carry out his attack on buildings. Even when securities tried to stop Heemeyer and his Killdozer, he successfully destroyed every building in the path of his Killdozer.

4. He Destroyed 13 Buildings in 2 Hours

After Heemeyer climbed into his Killdozer and sealed himself off, he drove through the walls of his shop and as one would expect, he began by destroying the concrete plant, town hall, the office of the local newspaper that editorialized against him, the home of a former mayor, and another store of a man mentioned in his lawsuit.

By the time the Marvin Heemeyer’s Killdozer revenge was done, he had destroyed 13 buildings worth about $7 million within the 2 hours of his operation.

5. The Killdozer was Indestructible Just as Marvin Intended

In trying to stop the attack, security personnel stood their grounds and fired several bullets and explosives such as a flash-bang grenade at the Killdozer, but it was fruitless endeavor because Marvin ensured his work was foolproof.

6. Who Died During the Killdozer Revenge?

Although buildings went down, shots were fired, and explosives were used, there were no records of death or injury related to the attack except for Heemeyer himself.

Authorities reported that people who occupied the buildings where the attacks were carried out had received the message through a reverse 911 call and had left the buildings before Heemeyer began his revenge. Therefore, there were no lives lost except for that of the perpetrator.

7. What Happened to Marvin and His Killdozer after the Revenge?

In an attempt to destroy a hardware store, the bulldozer got trapped in the basement of the store and could not move any further. Having been prepared to die on his own terms, Heemeyer shot himself.

In an attempt to get Heemeyer out, the police used several explosives but failed. Hence, they used an Oxyacetylene Cutting torch to remove the attacker at about 2:00 am on June 5. The town later announced its intention to sell parts of the bulldozer in pieces.

After the incident, the list of the places he planned to destroy and the people who sided against him in the dispute was gotten in his apartment together with notes. The only place not destroyed as he had intended on his list was a catholic church.
