The Luby's massacre was a mass murder that took place on October 16, 1991, in Killeen, Texas. George Hennard crashed his pickup truck through the front plate glass window of the Luby's Cafeteria at 1705 East Central Texas Expressway, shot 43 people, exchanged shots with responding police, and then hid in a bathroom and fatally shot himself.

It was the deadliest shooting rampage in American history until the Virginia Tech massacre in 2007, and is now the third deadliest mass shooting behind the Sandy Hook Elementary School shooting. It remains the deadliest non-school shooting rampage in America.

On October 16, 1991, 35-year-old George Pierre "Jo Jo" Hennard, an unemployed merchant mariner or able seaman who was described by others as angry and withdrawn, with a dislike of women, drove his blue 1987 Ford Ranger pickup truck through the front window of a Luby's Cafeteria at 1705 East Central Texas Expressway in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! This is payback day!",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, ten of them with a single shot to the head, and wounded another 20 before committing suicide. Approximately 140 people were in the restaurant at the time.
