On August 1, 1966, Charles Joseph Whitman, an architectural engineering student at the university, barricaded himself in the observation deck of the tower of the Main Building with a scoped Remington 700 deer rifle and various other weapons. In a 96-minute standoff, Whitman killed 14 people and wounded 32 more (including 1 who died 35 years later of his wounds). Two police officers and a deputized manager from the co-op from across the mall climbed to the top of the tower and shot him to death.
