FLORENCE, Ariz. (AP) -- An Iraqi man who once helped anti-government forces try to overthrow Saddam Hussein is set for arraignment on multiple state counts of attempted murder after authorities say he detonated a homemade explosive device outside a Social Security Administration office in Arizona.
Abdullatif Ali Aldosary, 48, was convicted last September in federal court and sentenced to five years in prison on three counts related to weapons possession.
Authorities said they found guns and hundreds of rounds of ammunition when they searched his home after the explosive was detonated on Nov. 30 outside a Social Security office in Casa Grande.
Aldosary isn't allowed to own firearms because of a previous felony conviction.
Separately, Aldosary faces much more serious charges in state court related to the bombing and a 2012 killing.
He was scheduled to be arraigned Friday in Pinal County Superior Court on more than a dozen counts, including 14 charges of attempted first-degree murder, arson and use of explosives. Nobody was injured in the blast.
Prosecutors said the attempted murder charges stem from 14 employees who were inside the building at the time of the explosion.
In yet another state case, Aldosary is charged with murder, aggravated assault with a deadly weapon, and two firearms counts in the Nov. 27, 2012, killing of a man at the Arizona Grain processing facility in Maricopa, about 35 miles south of Phoenix.
Aldosary also was employed there for a time. Authorities have not released a motive in either the bombing or the killing and have declined to discuss whether they were related.
Aldosary came to the United States legally in 1997 from his home country of Iraq.
In 2008, he pleaded guilty to felony aggravated harassment charges. He was sentenced to two months in jail and three years of probation, but he was later ordered to serve a year in prison.
Aldosary had sought help from U.S. Rep. Paul Gosar's office in 2011 in obtaining permanent residency. Gosar has said he contacted Homeland Security, which responded in a letter that Aldosary's case had been put on hold "pursuant to the terrorism-related grounds of inadmissibility" under a section of the Immigration and Nationality Act.
Authorities say he was denied a green card because he fought with anti-government forces trying to overthrow Saddam Hussein in 1991 in Basra, Iraq.
