Violence in a college town heralds the end of innocence in American Justice: Mass Murderer -- An American Tragedy. The summer of 1966 arrived heavily as it did every year in Austin, TX. With temperatures soaring into the 100s, students drifted in and out of cafes and classrooms on the university campus. One student, however, would welcome the death of 16 innocent people before the day was through. Charles Whitman started his killing spree by murdering his wife and mother in the wee hours of August 1. He left a note saying he didn't want them to live in the world he was sure to leave behind. Then he walked calmly to the observation deck of the tower at the center of campus and began picking off victims one by one, hitting 31 in all. From a pregnant 18-year-old to a policeman, Whitman's subjects were randomly chosen. He proceeded to shoot for over 90 minutes before cops were able to take him down. Since he died instantly, Whitman only left a diary and a few letters to explain why he became one of the nation's most hated assassins. A&E relives that infamous day with the help of witnesses and criminologists. ~ Sarah Ing, Rovi
