Where'd They Get Their Guns?

An Analysis of the Firearms Used in High-Profile Shootings, 1963 to 2001

Date: January 13, 1999

Location: Triad Center office building, Salt Lake City, Utah

Alleged Shooter: Di-Kieu Duy

People Killed: One

People Injured: One

Firearm(s): 9mm pistol


Di-Kieu Duy stormed into a Salt Lake City office building claiming that someone in the KSL-TV newsroom was harassing her. However, she ended up on the fourth floor and allegedly shot an AT&T employee and the building manager. Duy had a history of schizophrenia and erratic behavior, as well as numerous misdemeanor arrests.

How Firearm(s) Acquired

The firearm used in the shooting was attained legally at a Taylorsville gun shop hours before the shooting. Despite being treated for schizophrenia through an outpatient mental health treatment program, and accumulating a criminal history that included stalking, disorderly conduct, interfering with an arrest, and illegally carrying a concealed weapon, Duy was not prohibited from buying a firearm. Her mental health treatment had not been involuntary and all of her arrests were misdemeanors, therefore Duy was not prohibited from purchasing a firearm.
