The suspect in a deadly Arizona rampage purchased a firearm legally after passing an FBI background check.
Loughner, accused of killing six people, shooting Arizona Democratic Rep. Gabrielle Giffords and wounding 13 others, did not present a concealed weapons permit so he was required to pass an FBI background check.
Records obtained from the Pima County, Ariz., criminal database show Loughner was arrested in 2007 for possessing drug paraphernalia, a misdemeanor charge.
The records suggest that Loughner paid a $20 fee and completed a court-ordered program for drug offenders.
