Richard Speck murdered eight nurses in 1966 but was never classed as a serial killer. However, because he murdered them during one horrendous night, he joined the long list of spree killers. Serial killers have to kill over a period of time.

There are, however, other murders that people have questions about Speck’s involvement. He would have been classified as a serial killer if he had been charged with these crimes. However, as these cases were never assigned to him, he is officially classified as a spree killer.

The murders were no less horrific, and Speck will be remembered for many years as a violent, sadistic killer.
