Hristo Georgiev (serial killer)
The operation wasn't completely fruitless however, as it lead to the investigation of 17 persons with criminal backgrounds, 25 mentally ill, 8 relatives of Hristov and 9 suspects. Eventually, 13 instances of domestic violence and two acts of hooliganism were discovered.
On October 10, 1979, on "General Liprandi" Street in Sofia's "Hadzhi Dimitar" District, the body of 19-year-old Tsvetanka Stancheva was found. She had been killed with a sharp object. A man, who was collecting bricks from a nearby abandoned building, had discovered the grisly scene. The interesting in this case is that the victim was infected with syphilis, which lead the investigators to interrogate all the registered people suffering from the same disease, who had not revealed the source of how they got it. Taking into account Tsvetanka's life, the theory of one of her suitors killing her was considered, as well as that of a psychopath. The case was then nicknamed "The Provincialist".
