On November 12, 1998, 23 year old college student, Katarzyna Zowada, had plans to meet her mother at a psychiatric clinic in Kracow, Poland where Katarzyna was being treated for depression. But Katarzyna never showed up. Almost two months later, a piece of human skin and a human leg were found in the Vistula river and were both determined to belong to Katarzyna. With little to no evidence, investigators spent years trying to track down her murderer. Then in 2017, an arrest would finally be made. But would there be enough evidence to prove this man murdered Katarzyna?
