The suspect in Saturday's deadly rampage purchased a firearm legally after passing an FBI background check, the company's vice president of hunting operations told FoxNews.com on Sunday.

Jared Lee Loughner, a 22-year-old man with a troubled past who law enforcement say may have been influenced by American Renaissance, a pro-white publication, bought the gun from Sportsman's Warehouse's Tucson store in November.

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. He did so"immediately and without incident," said Matt French, speaking from the Sportsman's Warehouse's Utah headquarters.

"To my knowledge, the firearm purchase was without incident," French said.

French could not confirm whether the gun purchased in November was the same gun allegedly used in Saturday's mass shooting, for which Loughner so far has been charged with five counts of murder and attempted murder. However, he said it was the only recent firearm purchase made by the suspect at their stores(...)
