GRANBY, Colo. -- A muffler shop owner who plowed a makeshift armored bulldozer into several buildings after a dispute with city officials was found dead of an apparent self-inflicted gunshot wound after a SWAT team cut their way into the machine early Saturday, authorities said.
The driver, identified by the town manager as Marvin Heemeyer, appeared to have shot himself, said Grand County Sheriff Rod Johnson.
Officers looking through the square-foot hole cut into the metal casing could see Heemeyer's body with a gun lying nearby, Johnson said. Authorities planned to use a crane to lift the armor shell off the bulldozer, the sheriff said.
Heemeyer plowed the armor-plated bulldozer into the town hall, a former mayor's home and at least five other buildings Friday before the machine ground to a halt in the wreckage of a warehouse.
City officials said he was angry over a zoning dispute and fines for city code violations at his business in the town about 50 miles west of Denver.
Authorities detonated three explosions and fired at least 200 rounds against the heavy steel plates welded to the bulldozer, which looked like an upside-down Dumpster. After the third explosion failed, officials used a cutting torch to open the square-foot hole early yesterday, county Emergency Management Director Jim Holahan said.
Holahan said Heemeyer was armed with a .50-caliber weapon but appeared to have deliberately avoided injuring anyone during the rampage, which began about 3 p.m. Friday. No other injuries were reported.
Undersheriff Glen Trainor said the dozer's armor plates consisted of two sheets of half-inch steel with a layer of concrete between them.
Grand County Commissioner Duane Dailey said Heemeyer apparently used a video camera and two monitors found inside to guide the dozer. Two guns were mounted in front and aimed through portals. Other portals were cut in the back. It was unclear how many guns Heemeyer had in the dozer.
Authorities speculated Heemeyer may have used a homemade crane found in his garage to lower the armor hull over the dozer and himself.
"Once he tipped that lid shut, he knew he wasn't getting out," Dailey said.
Residents of this mountain tourist town of 2,200 described a bizarre scene as the bulldozer slowly crashed through buildings, trees and lampposts, with dozens of officers walking ahead or behind it, firing into the machine and shouting at townspeople to flee.
"It looked like a futuristic tank," said Rod Moore, who watched the dozer rumble past within 15 feet of his auto garage and towing company.
One officer, later identified as Trainor, was perched on top, firing shot after shot into the top and once dropping an explosive down the exhaust pipe.
Trainor said he believes Heemeyer spent months armoring the bulldozer, and investigators were looking into whether he had help.
Town manager Tom Hale said owners of all the buildings that were damaged had some connection to Heemeyer's disputes.
Crumpled patrol cars and service trucks lay in the dozer's path. A pickup was folded nearly in half and had been rammed through the wall of a building.
