Serial Killing Cop : The True Story of Mikhail Popkov

Mikhail Popkov may be the most prolific serial killers in world history. 
He led a double-life as a family man with a wife and a young daughter. But after the dissolution of the Soviet Union, Popkov was able to take advantage of the lack of police authority to get away with his most barbaric fantasies. 
Using his police uniform as a cover, he would lure unsuspecting women into his squad car where he would drive them to an isolated forest to kill them. His murders would go unabated for close to twenty years until Russian authorities finally utilized DNA evidence to match Popkov with the killings. 
He was able to evade authorities because he was the authority. 
Both he and his wife were police officers. 
This is their story.
