Kot: The Vampire of Krakow Killers: Behind the Myth : Season 1 Episode 2

For two years the baby-faced killer Karol Kot terrorised the Polish city of Krakow. Unlike many serial killers he appeared to have no fixed modus operandi when targeting his victims, which made tracking him down difficult. He began his attacks on elderly women, but after a two-year break, he moved to attacking children. An 11 year old boy is found stabbed to death: the boy's internal organs have been punctured in the frenzied attack. A young girl is targeted shortly afterwards. Witness statements link a schoolboy with the crimes. The country is horrified. The killer is finally caught when he confides in a potential partner. His attempt to impress her backfires. Instead she's horrified and goes straight to the police. Once in custody, the schoolboy Kot reveals he drank the blood of his victims as they lay dying.
