"The elevator just opened next to the one I was in and he or she had a gun and.."

Swat teams swarmed the Triad Center while a telphone voice mail system recorded the sounds of KSL employees scrambling for safety.

It happened Thursday, when a woman opened fire in the lobby of KSL-TV.

We have new details this evening about the suspect, and how she was able to purchase a handgun, despite a long and disturbing record of criminal behavior. News Specialist Richard Piatt reports.

In hindsight, it's easy to say this woman shouldn't have had a gun. She has been arrested several times for crimes involving threats of violence. And she has a long record of mental illness. But according to state law, the sale of that 9 mm handgun was technically legal.

Doug's Shoot "N" Sports was closed Friday morning as police searched the store's records. Their investigation confirms that the nine millimeter gun used in the KSL shooting was bought here.

Ballistic tests will confirm whether the ammunition came from here too. But legally, police say Doug's Shoot "N" Sports has done nothing wrong.

The request for the suspect's gun purchase was screened at the state Bureau of Identification. It ran a standard background computer check on her request to buy the gun. It was approved.

Jamie Allred, of the Bureau Of identification, says, "The operator had access to information that showed some arrests, some criminal activity, but nothing that were grounds for denial."

De Kieo Duy was charged with stalking, disorderly conduct and assault against a police officer in 1996.

She was also charged with Interfering with an arrest and carrying a concealed weapon in a separate case.

But the charges were either dismissed or pleaded from felonies to misdemenors. That means, under state and federal laws, that the gun sale was proper.

Questions about her mental state were also not in the computer system. A judge has to issue a ruling in order to prevent someone from purchasing a gun.

Simply because someone has seen a psychiatrist or had examinations, or has been treated for a mental defect doesn't necessarily put them in a classification for denial.

Even though it's employees did nothing legally wrong, witnesses reported the woman acting strangely the day she bought the gun. A gun shop does have the right to refuse a purchase for any reason.

An attempt to ask further questions at Doug's Shoot 'N' Sports was answered with a 'no comment', and a hung-up phone.
