Case 273

The Beast of Mława

*** Content warning: Child victims, serial rapist, stalking ***

When the Koneva family fled to England to escape the war-torn Balkans, their hopes for a peaceful new beginning were soon shattered. In May 1997, an unknown intruder entered their London home and claimed the life of 12-year-old Katerina Koneva. The subsequent investigation spanned multiple countries and unravelled a frightening and prolific figure known as “The Beast.”
