A 9:30 a.m. Sept. 14 pre-trial conference has been scheduled for McDonald County white supremacist Robert Joos at the federal courthouse in Springfield.
Joos is being held without bond on a charge of being a felon illegally possessing a firearm.
Joos was arrested in connection with a federal investigation of a racially-motivated 2004 bombing in Scottsdale, Ariz. National white supremacist leader Dennis Mahon and his brother Daniel were charged with that crime.
ATF agents executing a search warrant on Joos' property June 24 found bomb-making materials, according to documents filed in U. S. District Court for the Western District of Missouri.
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.
