Чикатило

He killed and remained unpunished for more than ten years, more than fifty people died at his hand. Instead, an innocent person was convicted and shot. For a long time, the murders committed by him could not be combined into one case. Maniacs of this caliber simply did not exist in the USSR, so the law enforcement agencies were not ready to fight the "Mad Beast", as journalists later dubbed it. To capture Chikatilo, vigilantes, police officers, prosecutors, psychiatrists were involved, and new methods of investigation were developed that will help save innocent people.
