FBI agents believe they have the man responsible for bombing the Social Security building in Casa Grande and according to court documents, the explosives used are similar to the ones in many bomb plots including terrorist attacks.
47-year-old Abdullatif Ali Aldosary made his first court appearance today in Phoenix, but he did not enter a plea.
Just before 8:30 on Friday morning, a bomb exploded at a doorway of the Social Security building in Casa Grande.
Several witnesses saw a dark colored car speed away. One of them managed to get the license plate number.
Within an hour, police officers tracked arrested Aldosary at his Coolidge home while he was washing his car in the driveway. Investigators believe he was trying to wash off the evidence of the bomb blast.
According to a court affidavit, FBI agents got a search warrant and found bomb-making recipes in Aldosary's home along with a receipt from a ChemLab Supply in Phoenix for the purchase of nitric acid.
The affidavit also said two guns were found in the attic along with several hundred rounds of ammunition.
This is not Aldosary's first run-in with the law.
In September, the Iraqi refugee was charged with assault and disorderly conduct, and served time for aggravated harassment charges after he threatened an employer in 2008.
A second hearing has been scheduled for Wednesday.
