Weapons Came From Gun Show

Federal investigators have determined that three of the four weapons used in the Littleton massacre were purchased for the boys at a gun show, CBS News Correspondent Jim Stewart reports.

Thousands of firearms are routinely sold anonymously at totally unregulated gun shows around the country.

Colorado authorities say it is true that they've questioned an 18-year-old female friend of one of the two suspects, but that's all they'll say.

"Nothing's been confirmed as far as her supplying the weapons. They are simply asking her and questioning her on that line," sheriff's spokesman Steve Davis said.

However, sources say they've determined that the young woman did, in fact, purchase two 12-gauge shotguns at a gun show recently -- the very weapons police believe caused most of the bloodshed inside Columbine High.

In addition, agents say a rifle used in the shooting also came from a gun show -- while the fourth weapon, a Tec-9 pistol, was initially purchased by an adult at a Denver area store. It is not clear how it came into the boys' possession.

Sources said investigators learned of the gun-show purchases from one of the young men's diaries.

"If you look old enough you are not going to be asked questions," says Tom Diaz, a gun-control advocate. "Let me put it to you this way: It's as easy to buy a gun at a gun show as it is to buy a pack of cigarettes."

Gun sales at a licensed dealer must be accompanied by a federal form answering questions about the buyer. But at gun shows, most sales require no exchange of information, only that of cash.

It is not illegal for an 18-year-old to go to a gun show and purchase a shotgun. Nor would it be illegal for her to give or sell it to another 18-year-old. But it is a different story altogether, investigators say, if you make such a purchase and have a pretty good idea what the guns would be used for.
