Andrzej Kunowski (29 March 1956 – 23 September 2009), known as The Beast of Mława, was a Polish murderer, serial rapist and suspected serial killer. A prolific sex offender in his native country, Kunowski later moved illegally to England, where he murdered 12-year-old Macedonian girl Katerina Koneva in 1997. Sentenced to a whole life order for this crime, he was detained at the HM Prison Frankland until his death in 2009. He remains the prime suspect in the disappearances of three girls between 1992 and 2000, for which he was never charged.
