Mikhail Popkov

Mikhail Viktorovich Popkov is a Russian serial killer, rapist, and necrophile who committed the sexual assault and murder of eighty-seven girls and women between 1992 and 2011 in Angarsk, Irkutsk, in Siberia, and Vladivostok in the Russian Far East, although he has confessed to and is suspected of at least ninety in total. He is known as "the Werewolf" and "the Angarsk Maniac" for the particularly brutal nature of his crimes; he would extensively mutilate the bodies of his victims and perform sexual acts on them. Popkov was also known as "the Wednesday Murderer" because most of his victims' bodies were found on Wednesdays. He is the single most prolific serial killer in Russian history.
