MORRISON, Colo. -- Alcohol, Tobacco and Firearms agents and four different bomb squads served a federal search warrant on an Morrison home after arresting one of its residents Thursday morning.
According to the ATF, Richard Sandberg, 35, was taken into custody Thursday morning. He was indicted on charges of building and storing a large stash of explosives.
Shortly after 10 a.m., bomb squads from ATF, Denver, Jefferson County and Colorado Springs were assisting in search warrant at 4648 South Swadley Way that was related to Sanberg's arrest.
The ATF called their search and arrest part of an ongoing investigation with the Denver Police Department.
The federal complaint against the suspect says, "Sandberg said that he specialized in demolition and these [devices] make a big boom and not a small boom and said that he has 11 homemade "frags" and the kill zone would be 20 meters and the hurt zone is 60 meters."
The U.S. Attorney's Office confirms that in the past, Sandberg has threatened to kill people.
The large bomb squad trucks and crews from all levels of law enforcement caused quite a scene in the neighborhood.
Investigators spent almost the entire day going over every inch of the home.
Tiffany Maddox lives near Sandberg's home. "He's out there at all hours of the night banging and saws and welding."
"Sounds to me like the house is barricaded from the inside which requires pipe bombs, etc.," says neighbor Earl Maddox.
