On October 16, 1991, 35-year-old George "Jo Jo" Pierre Hennard, an unemployed merchant seaman who was described by others as angry and withdrawn, with a dislike of women, drove his blue 1987 Ford Ranger pickup truck through the front window of a Luby's cafeteria at 1705 East Central Texas Expressway in Killeen. Yelling "This is what Bell County did to me!", Hennard then opened fire on its patrons and staff with a Glock 17 pistol and, later, a Ruger P89. He stalked, shot, and killed 23 people while wounding another 20 before committing suicide. At least 80 people were in the restaurant at the time.

The first victim was local veterinarian Michael Griffith, 48, who ran to the driver's side of the pickup truck to offer assistance to the driver after the truck crashed through the window. Hennard also approached 32-year-old Suzanna Hupp and her parents. Hupp reached for her .38 revolver in her purse, only to realize she had left it in her vehicle. Her father Al, 71, rushed at Hennard in an attempt to subdue him but was fatally shot in the chest. A short time later, as Hupp was escaping, her mother Ursula, 67, was shot in the head and killed as she cradled her wounded husband.

During the massacre, Hennard allowed a woman and her four-year-old child to leave. Another patron, Tommy Vaughn, threw himself through a plate-glass window, sustaining injuries, but by doing so he created an escape route for himself and other customers.

Hennard reloaded several times and still had ammunition remaining when he committed suicide by shooting himself in the head after exchanging shots with, and being wounded by a responding police officer.
