John Markell, the owner of Roanoke Firearms, said today that he had been interviewed by three agents from the federal Bureau of Alcohol, Tobacco and Firearms about Cho's purchase of a Glock 9 mm handgun.
"I feel terrible about this," Markell told ABC News at his store today, which is part gun shop, part pawn shop on the outskirts of Roanoke.THE BLOTTER RECOMMENDS
Markell said Cho's gun and a box of 50 bullets cost $571. He said Cho paid by credit card and left the store with the gun.
Markell said Cho was "a clean-cut college kid," and the transaction was entirely legal under Virginia law. "He was as cordial as could be, and there was nothing unusual in his manner that suggested any thing wrong," Markell said. Markell said he was not present when Cho bought the gun, but that he had produced a state driver's license and an immigration card.
Law enforcement officials tell ABC News Cho bought his second weapon, a .22 caliber handgun, also in Virginia, within the last week.
"This was no spur of the moment crime. He's been thinking about this since at least the time he bought the first gun," said former FBI agent Brad Garrett, an ABC News consultant.
Under Virginia law, state residents can only buy one handgun in any 30-day period, suggesting Cho bought his second weapon after April 13 or sometime over the weekend.
"He clearly spent some time figuring out how he was going to take care of business once classes began on Monday morning," said Garrett.
The date of the first gun purchase will likely serve as the time of "some triggering mechanism that was very important" to Cho said Garrett, an expert on profiling murderers.
