Over the course of one week in New York City in 1985, a violent and brutal killer wielding an axe took the lives of two women: 85 year old Janet Scott and 58 year old Ruth Potdevin. Both women were killed in hotels within days of each other, less than a half mile apart. While the crimes themselves were grisly enough, the killer went further by leaving a gruesome puzzle behind at each scene. While the NYPD believed they would capture the assailant, his wrath disappeared just as mysteriously as it had originally materialized. Did he finish what he aimed to do or did he simply move on to kill again, evading police once more?
