PHOENIX - A white supremacist likely will spend the rest of his life behind bars after a federal judge sentenced him to 40 years in prison Tuesday for a 2004 bombing that wounded a black city official in suburban Phoenix.
Jurors in February convicted Dennis Mahon, 61, of three federal charges stemming from a package bomb that injured Don Logan - Scottsdale's diversity director at the time - and a secretary.
They stopped short of finding him guilty of a hate crime after a six-week trial that included dramatic testimony from Logan and a female government informant dubbed a "trailer park Mata Hari" by defense attorneys.
In handing down the sentence, U.S. District Judge David Campbell said he believed the bombing was premeditated and done to promote an agenda of hate and racism.
He called it an "act of domestic terrorism."
Mahon, meanwhile, maintained his innocence, telling the crowded courtroom: "I didn't do this bombing."
He said he felt bad for the victims, "but I can't apologize for something I didn't do."
Mahon had faced between seven and 100 years in prison. Since there is no parole in the federal system, he likely will spend the rest of his life behind bars.
His identical twin brother, Daniel, also faced a charge in the case but was acquitted.
The package bomb detonated in Logan's hands on Feb. 26, 2004, in a Scottsdale city building.
Prosecutors alleged the Mahon brothers bombed Logan on behalf of a group called the White Aryan Resistance, which they said encourages members to act as "lone wolves" and commit violence against non-whites and the government.
They showed surveillance tapes at trial of the brothers referring to Logan in racial slurs.
They also played a voicemail that Dennis Mahon left at Scottsdale's diversity office just months before the bombing in which he angrily said: "The white Aryan resistance is growing in Scottsdale. There's a few white people who are standing up."
Defense attorneys said someone working for the city of Scottsdale was likely the perpetrator because Logan's job made him unpopular.
