You have to admit, it's one badass machine!
Grand County undersheriff Glen Trainor said the bulldozerís armour plates consisted of two sheets of half-inch steel with a layer of concrete between them.
Heemeyer used a video camera and two monitors found inside to guide the bulldozer, Grand County Commissioner Duane Daley said. Two guns were mounted in front and aimed through portals. Other portals were cut in the back.
He is thought to have used a homemade crane found in his garage to lower the armour hull over the bulldozer and himself.
"Once he tipped that lid shut, he knew he wasnít getting out," Daley said.
Investigators searched the garage where they believe Heemeyer built the vehicle and found cement, armour, steel and a homemade crane.
