Richard Benjamin Speck (December 6, 1941 – December 5, 1991) was an American mass murderer who systematically raped one and tortured and murdered eight student nurses from South Chicago Community Hospital on the night of July 13 into the early morning hours of July 14, 1966. He was convicted at trial and sentenced to death, but the sentence was later overturned due to issues with jury selection at his trial. Speck died of a heart attack in 1991, after 25 years in prison. In 1996, videotapes featuring Speck were shown before the Illinois State Legislature to highlight some of the illegal activity that took place in prisons.
