An affidavit filed by Kevin Farnsworth, links Joos to two men charged with a 2004 bombing in which the director of diversity and dialogue for the city of Scottsdale, Ariz., Don Logan an African American, was injured.
The information against Joos was collected by a undercover ATF agents.
(2) Over the course of the past several years, ATF SA Tristan Moreland has engaged in an investigation into a February 26, 2004, bombing incident that injured the
Director of Diversity & Dialogue for the City of Scottsdale, Arizona. The injured director, identified as Don Logan, is a black male. The subsequent investigation
has focused on several persons involved in the white supremacist movements throughout the United States. Through this investigation, SA Moreland identified brothers
Dennis and Daniel MAHON as suspects in the Arizona bombing.
(3) In January 2005, SA Moreland initiated an undercover investigation of the MAHON brothers and others. To date, several ATF undercover agents (UCAs) as well as an ATF
cooperating individual (CI) have been used in an undercover capacity to conduct this investigation. The undercover investigation continues through the present time.
(4) Investigators reviewing telephone records of one of the Arizona bombing suspects, Dennis MAHON, found that Mahon’s phone made several calls on the morning the package
bomb was left at the library. The first call made in that string of morning calls was to a cellular telephone number registered to Robert JOOS at 7:11am CST.
(5) In February 2005, the ATF CI and an ATF UCA met bombing suspects Dennis MAHON and Daniel MAHON in Catoosa, Oklahoma. During this time period, the MAHON brothers told
the CI and UCA about a “retreat” location in Missouri that he and other members of the “movement” used as a survival training location. MAHON told the CI that this location is a remote 200-plus acre property occupied by an individual named Robert JOOS. MAHON further described JOOS as a longtime, white supremacist associate and an expert on weapons, explosives, bomb making and general survival skills. MAHON provided the CI with a map to JOOS’ property and a phone number to contact him. Over the course of calendar year 2005, through the present, the CI had several telephonic contacts with JOOS and visited him on three (3) occasions.
Most of the rest of the affidavit details a large amount of weapons located all over Joos' ranch. As a convicted felon (unlawful use of a weapon in McDonald County Circuit Court in 1997) Joos is not allowed to possess firearms.
