Twin brothers from Illinois who authorities say are white supremacists have been charged in a 2004 bombing that injured the black diversity director in the Phoenix suburb of Scottsdale.
Dennis and Daniel Mahon were arrested Thursday in their Davis Junction, Ill., home. Authorities say they had assault weapons, hundreds of rounds of ammunition and white supremacist materials.
The indictment charges the brothers with conspiracy to damage buildings and property by means of explosive.
They are accused of sending a package that detonated in Don Logan's hands at the Human Resources Complex in Scottsdale.
