On December 1, 1988, 18‑year‑old Hispanic security guard Armando Enrique Torres was stationed unarmed at Universal Studios’ main gate in Universal City, California, when a visitor opened fire. The shooter, 42‑year‑old Nathan Nicholas Trupp, had been riding the studio tour tram and, after being refused use of the phone in the guard shack, returned and shot both Torres and his 27‑year‑old coworker Jeren Beeks in the head. Torres was critically wounded, taken to St. Joseph Medical Center in Burbank, and died the following day at 4:35 p.m.; Beeks was killed at the scene.

A Los Angeles County sheriff’s deputy exchanged gunfire with Trupp immediately afterward, wounding him; he was taken into custody and hospitalized. Trupp was already wanted in connection with an alleged November 29, 1988, triple homicide in Albuquerque and later faced five murder charges total. He pleaded guilty to the two California counts but was found not guilty by reason of insanity and committed to a state mental hospital under the terms reported. No other suspects or arrests were made in Torres’ killing.

Did anyone who knew Torres, worked with him, or was at Universal Studios that evening ever come forward with additional details?
