In what is still one of the most indelible mass shootings in U. S. history, Charles Whitman, an ex-Marine who had qualified as a sharpshooter, barricaded himself into the Tower on the campus of the University of Texas at Austin, on August 1, 1966, and opened fire on innocent bystanders for 96 minutes.
He had already killed his mother and wife, and three others on the way up the Tower stairs. He used a scoped Remington 6mm deer rifle, an M-1 carbine, a .35 caliber Remington pump rifle, a .357 magnum revolver, a 9mm Luger, and a sawn-off 12-ga pump shotgun.
He commenced firing at 11:48 am, and indiscriminately killed 11 civilians, and wounded 32 more, before police officers were able to get up to the observation deck and shoot him down.
He shot a pregnant woman through the stomach. This was probably a deliberate attempt to kill the fetus, which succeeded. The mother, Claire Wilson survived. He shot Paul Sonntag, a student, through the mouth, from 400 yards, then shot his fiancée, Claudia Rutt in the chest, as she attempted to drag him behind cover.
Ambulances and even an armored car were employed to rescue pinned-down civilians. An ambulance driver, Morris Hohmann, was shot through the leg.
In true Texas style, civilians in the area ran to their vehicles and brought out their own deer rifles, shotguns, and handguns, and returned fire to the top of the tower, pinning Whitman down well enough for nine officers to get to the top of the building. Ramiro Martinez and Houston McCoy flanked Whitman, and Martinez emptied his revolver at him, wounding him. McCoy then fired two rounds of 12-ga 00 buckshot into the head, neck and left side of Whitman, killing him instantly.
Martinez then grabbed the shotgun from McCoy, ran up to Whitman’s body, and shot him again in the upper left arm, point blank. There is a photo of Whitman’s dead body on Wikipedia. He was subsequently found to have a glioblastoma, a brain tumor that could have caused his erratic mentality, as he had not always been homicidal.
