ATF agents executing a search warrant on white supremacist Robert Joos' property in McDonald County Wednesday found bomb-making materials, according to documents filed today in U. S. District Court for the Western District of Missouri.
The government posted the information in its effort to prevent Joos from being released on bond.
The search uncovered "more than a dozen miscellaneous firearms," as well as "materials for constructing improved explosive devices, including blasting caps, gunpowder, and fuses."
In addition, the documents indicate, Joos provided undercover ATF agents with information on how to build a bomb.
Joos was charged Wednesday with being a felon illegally owning firearms. The arrest was made in conjunction with the arrests of white supremacist national leader Dennis Mahon and his brother Daniel in connection with a 2004 racially-motivated bombing in Scottsdale, Ariz.
Court documents also indicate Ian Lewis, an assistant federal public defender, will represent Joos.
