Vladimir Kolpakov

Vladimir Yevgenyevich Kolpakov (; 3 October 1961 – 2022) was a Soviet-Russian serial killer who was linked via DNA to the murder and subsequent dismemberment of an underage girl in Ulyanovsk dating back to 1987. At the time of his identification, he had served a prison sentence for murdering two male acquaintances during a dispute, and was the prime suspect of two similar murders dating back to the late 1980s.

Before he could be arrested for the crime, Kolpakov committed suicide. The identification of Sazonova's murderer is one of the oldest cold cases to be solved in modern Russian history. Provided by Wikipedia
