Goodwin said it is illegal for a person to possess a firearm with an obliterated serial number, meaning the number has been removed, scratched off or distorted.
The office also sees a number of cases involving "straw purchases," meaning a person who buys a firearm from a licensed dealer for another person, who may or may not be permitted to purchase or possess the weapon.
Loew recalled the case of James Gray, a convicted felon from New Jersey, who found a taxi driver in West Virginia to buy guns for him. It happened a little more than 10 years ago, he said.
Gray could not buy a gun because of his status as a felon. The form that must be filled out asks several questions that could determine whether a person is eligible to purchase a gun. For example, it asks whether the would-be buyer has been convicted of a felony. The FBI conducts the background checks once those forms are returned to the retailer.
The taxi driver lied on the forms, claiming the weapons were for her, and bought between 50 and 100 guns for Gray, Loew said. When the same person buys multiple firearms over a 30-day period, red flags begin to go up, he said.
Agents from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives spoke to the woman, and she admitted what she had been doing and agreed to cooperate. The next time she purchased weapons for Gray, officers were there to arrest him.
Both were charged and convicted, although the taxi driver, whose name was not given, received a lighter sentence because she cooperated.
Goodwin said people often express fear that a public firearms registry would identify the owners of guns. He said firearms currently are tracked by make, model and serial number, and that information is provided only if a person buys a gun from a licensed dealer.
Goodwin declined to comment on gun control proposals being debated across the nation.
He said it was his understanding that none of the current proposals before Congress conflicted with the Second Amendment.
"We're going to continue what we've always been focused on and that's keeping guns out of the hands of dangerous people," Goodwin said.
