Srbski terorist Marko Boskic A Peabody, Mass., construction worker accused of heinous war crimes in Bosnia was indicted Wednesday. NewsCenter 5's David Boeri reported that prosecutors said that Marko Boskic lied on immigration documents to get into the United States. It could be the first step to getting him deported to Bosnia, where he could faces charges in the worst case of genocide in Europe since World War II. In 1995, the town of Srebenica, in Eastern Bosnia, became synonymous with mass murder. Bosnian Serb forces exterminated 7,500 Muslim men and boys. One of the soldiers who allegedly belonged to the notorious killing squad has been living in Peabody, Mass., since 2000. "The indictment further alleges that Boskic himself personally participated in the brutal executions," U.S. Attorney Michael Sullivan said. The indictment charges Boskic with committing immigration fraud by lying about his service in the Army of the Republic of Serbska. "We will take all appropriate legal measurements to find, investigate and prosecute terrorists," Sullivan said. It took officials more than four years to find Boskic after he entered the United States. In September 1999, he applied for refugee status and immigration. In February 2000 while living in Germany, he swore an oath during his interview. Just two months later in April, he was admitted to the United States. "The applicant is interviewed. There is a name checked on FBI (news - web sites), CIA (news - web sites) and State Department data bases," Immigration and Customs Agent Kevin W. Jarvis said. But for some reason, Boskic's name wasn't on any watch list. His alleged lies went undetected. "We are all benefiting from hindsight. Clearly, if that information was known in 1999, he would not have had access to country," Sullivan said. He did get access to the country in April 2000, and two years passed. In June 2002, the Joint Terrorism Task Force was notified that he was a person of interest and was perhaps living in Massachusetts. After an intensive investigation and another two years, officials made an arrest in August and an indictment was handed up. "People like Boskic are not welcome in the United States, and the avenues for their entry are closed," Immigration and Customs Special Agent Robin Avers said.
