In 1933, Czechoslovakia was rocked by a gruesome murder. Two suitcases were found on 2 September, independently of each other, in the Slovak cities of Bratislava and Košice. The suitcase that was found in Košice contained a woman’s torso, and in Bratislava, a woman’s severed head and legs. The perpetrator was never found, but 90 years later, researchers think they may have an answer.
