The country cult classic, “Psycho”, was composed by Leon Payne, a blind Texas country singer-song writer, after he’d read about fellow Texan Charles Whitman.
In 1966 Whitman had strangled his mother to death, stabbed his wife, and then headed to the top of the University of Texas Library tower and opened fire on an unsuspecting crowd, using his Marine corps sniper rifle, killing sixteen people. Whitman was gunned down by police.
