After killing his mother and his wife, Charles Whitman went to the top of the University clock tower after the lunch break and began to pick off the stragglers who remained. Seventeen people died due to the rampage that day, including Whitman himself, and thirty-one (some sources say thirty-two) others were wounded.
Police shot Whitman 6 times with a .32, and twice in the face with a 12-gauge shotgun from 5 feet away.
Whitman requested an examination of his body in his suicide note, to see what was wrong with him. The autopsy revealed a brain tumor, which has led to speculation that the tumor was responsible for his rampage.
Whitman left a suicide note behind, starting with “I don’t quite understand what it is that compels me to type this letter. Perhaps it is to leave some vague reason for the actions I have recently performed. I don’t really understand myself these days. I am supposed to be an average reasonable and intelligent young man. However, lately (I can’t recall when it started) I have been a victim of many unusual and irrational thoughts.”
He also left behind a letter explaining that he had killed his mother and why he did it, a letter explaining that he had killed his wife and why he did it, and two letters to his brothers, John & Pat.
