SOFIA – Corruption-plagued EU member Bulgaria was under pressure Monday to find the killer of a television journalist whose brutal murder at the weekend has shocked the country and sparked international condemnation. The body of 30-year-old Viktoria Marinova -- who presented a current affairs talk programme called "Detector" for the small private TVN television in the northern town of Ruse -- was found on Saturday. "All leads are being looked at" in the investigation including possible links to Marinova's professional activity, chief prosecutor Sotir Tsatsarov said Monday. Authorities earlier revealed that Marinova had been killed by blows to the head and from suffocation, and had also been raped. In no way, under any form, never have we received any threats -- aimed at her or the television," a journalist from Marinova's own TVN told AFP on condition of anonymity Sunday, adding that he and his colleagues feared for their safety.
