Vampire doctor and cannibal for several years worked in the hospital on forged documents

In one of the Russian cities 20 years ago, a man with extreme cruelty killed his classmate, and then drank his blood. The offender was caught and convicted, after another 10 years, he was in a psychiatric clinic. When he came out of there, he apparently decided to start a new life

as he did his documents, a university diploma, and got a job as a general practitioner in a local clinic. A man worked under such cover for several years, until one day when one of the attentive patients recognized him. Unfortunately, the story is silent about what happened to the unmasked doctor and whether he had new victims at that time.
