Karol Kot (18 December 1946 – 16 May 1968) was a Polish serial killer who terrorized Kraków, the city he was born and raised in, until his capture in June 1966.
Due to trial evidence and to the seemingly random choices of victims, which included children and elderly people, Kot was nicknamed the "Vampire of Kraków".
After the trial, in which Kot pleaded guilty to all the crimes he was charged with, he was sentenced to death on 14 July 1967.
After an appeal, the death penalty was reinstated, and carried out on 16 May 1968 when Kot was 21 years old.
