(ANSA) - ROME, JUN 17 - Milan prosecutors said Wednesday that Carabinieri police seized "significant" evidence during a search of the home of one of four Italians under investigation for murder over alleged "weekend sniper" trips to Sarajevo during the Bosnia war. The suspects allegedly paid large sums of money to Serbian militia so they could shoot Bosnian citizens for kicks during the 1993-95 Siege of Sarajevo, in which 11,000 people died. Prosecutors said the evidence seized included a photo of the suspect, a 65-year-old man residing in the Alessandria area, with technical equipment, and a silencer. The search took place on the basis of testimony given by his ex-wife and his former partner. During questioning, the former partner said the suspect told her he suffered from nightmares because he killed people in Bosnia in the 1990s. "He told me that he used to depart from Milan by plane and that there were some people with him who spent the weekend (....) being snipers and shooting Muslims," she told investigators. The man used the right to remain silent previously when questioned by prosecutors. The other suspects are a 80-year-old former lorry drive from the province of Pordenone, a 64-year-old businessman who lives in Brianza and a person from Tuscany. (ANSA).
