On August 11, 1976, 57-year-old glazier Elmer Wally Hensley was fatally shot during a sniper attack in downtown Wichita, Kansas. A gunman positioned on the rooftop of the 26-story Garvey building, which housed a Holiday Inn, fired on people below. Hensley was on the top level of a parking garage when a bullet struck his back. He managed to drag himself behind an air-conditioning unit but bled to death from his wounds.

Three people died that day and seven others were wounded. The other fatalities were 23-year-old loan officer Mark Falen and 56-year-old freelance photographer Joe Goulart. The shooter, identified as Michael Soles, carried two rifles and ammunition to the rooftop and fired for about 11 minutes before police shot and wounded him and took him into custody. Soles was tried; an insanity defense was raised and rejected, and he was convicted for the murders and the injuries he caused. The motive remains unclear.
