Epilogue: "The mistake in blood and semen analysis that allowed Andrei Chikatilo to be released in 1984 has never been adequately explained. Soviet Russia's head forensics expert has since asserted that she had discovered a rare new phenomenon--a man with a blood type of one kind, and a semen type of another. Her colleagues around the world scoff at the idea. Chikatilo led detectives to the graves of three undiscovered victims, proving conclusively that he was their murderer, and bringing the final body count to 52 dead. Thirty-five of the victims were children under the age of 17. Andrei Chikatilo was convicted of all 52 murders."
