PHOENIX — Two white supremacists from Illinois have been indicted in a 2004 mail bombing that injured the diversity director for the city of Scottsdale, federal authorities said.
Twin brothers Dennis and Daniel Mahon are charged with conspiracy to damage buildings and property by means of explosive, according to an indictment unsealed Thursday and filed June 16 in federal court. The indictment says the brothers intended to "promote racial discord" on behalf of the White Aryan Resistance, a decades-old group based in California.
The package detonated in the hands of Don Logan, who is black, on Feb. 26, 2004, in the city's Human Resources Complex. The blast injured Logan's hand and arm, and a secretary also was injured. Both required surgery and spent about a week in the hospital.
Authorities arrested the brothers Thursday in their Davis Junction, Ill., home and say they had assault weapons, hundreds of rounds of ammunition and white supremacist material.

Authorities didn't know if the brothers had attorneys.
A Missouri man's arrest Wednesday also arose from the bombing, according to the U.S. Attorney's Office in the Western District of Missouri. Robert Neil Joos, 56, was charged with being a felon in possession of firearms after a search of his property in rural southwest Missouri. An undercover investigation found that people involved in white supremacist movements in the U.S. met at a retreat location in Missouri owned by Joos, according to the attorney's office.
This event really struck home," Scottsdale police Sgt. Mark Clark said Thursday. "It caused a lot of fear and grief, and it's been a long road in the investigation, and we're certainly glad it's moving forward."
