William Montgomery, US Ambassador to Belgrade, recently informed the Serbian Minister of Police, Dusan Mihajlovic, that the American Administration is keenly interested in the case of mass shooting and discovery of a mass grave in Petrovo Selo where American citizens, the brothers Agron, Mehment and Jul Bitici are buried. The American Administration expects that the Serbian Government will carry out a detailed investigation into the deaths of these Americans, which merely increased Minister Mihajlovic's already considerable problems. In other words, the US Government expects that the new, democratic government in Serbia will undertake an investigation in which it will establish who issued the order for the committing of this crime.
