Chikatilo turned himself in by chance: the policeman's recording helped catch the madman. In the fall of 1990, not far from the train station, a policeman decided to check the man's documents - he was a suspect, but there was no reason to arrest him. A few days later, a girl's body was found nearby, and when witnesses described the alleged killer, everything pointed to this person. Former criminal investigation officer Amurkhan Yandiev told AiF how the chain of events unfolded that led to Chikatilo's arrest.
