Charles Whitman

Charles Whitman a.k.a. the Texas Tower shooter, who killed 16 and wounded 32 in the infamous 1966 Austin clock tower shootings, asked for an autopsy to be done after his death to determine what made him kill. The autopsy found a tumor pressing on his amygdala which possibly influenced his actions. He once even told his doctor that he had been having violent thoughts including “going up to the tower with a deer rifle and killing people.” The doctor just gave him Valium and sent him home. Charles knew he would occasionally lose himself in his rage so he would incessantly leave himself notes reminding him of his love for his wife and his mother. He had to constantly remind himself not to lose his temper. He did end up killing his wife and his mother, but he didn't know why he did this, according to his note. He had a burial with full military honors and his casket was draped in the American flag because he was a veteran.
