(ANSA) - BELGRADE, FEB 6 - Investigators are also looking into expatriation records from the time, recovering passport and travel document records, as well as airline tickets, in the case of the "weekend snipers," who paid to go and kill "for fun," including women, the elderly, and children, in Sarajevo, which was besieged by Bosnian Serbs between 1992 and 1995. According to what has been learned, the investigation, led by the Carabinieri's ROS special operations unit and coordinated by prosecutor Marcello Viola and prosecutor Alessandro Gobbis, is attempting to reconstruct those horrific journeys to Bosnia, beginning with reports, names, and testimonies and then checking border registers to determine whether specific individuals entered or left Italy for Sarajevo during that time. While the 80-year-old truck driver under investigation for aggravated and repeated voluntary homicide, who in his accounts, according to witnesses, referred to a "manhunt," will be questioned next Monday at the Milan prosecutor's office, the list of suspects is sure to grow. According to sources familiar with the investigation, several names are being investigated, including those from central and northern Italy. (ANSA).
