10 of the deadliest spree killers in history of the world (With Pictures)

7. Charles Whitman

On August 1, 1966, after killing his wife and mother, Charles Whitman, a former U.S Marine went to the University of Texas at Austin where he was an engineering student. He murdered 14 and wounded 32 more people over a period of 90 minutes before he was shot and killed by a police officer. Before his rampage Whitman wrote a suicide note where he requested an autopsy because he believe there was some biological reason for his urge to kill. He didn’t seem to understand his own reasons for killing his wife and mother, except to spare them of the embarrassment of his actions. An autopsy found a small pecan sized tumor in Whitman’s brain that could have affected his ability to control his emotions and actions.
