US officials have identified about 300 Bosnian immigrants who they believe concealed their involvement in wartime atrocities including the 1995 Srebrenica massacre, and are trying to deport at least 150 of them, The New York Times reported on Saturday. The immigrants were among refugees fleeing the violence in Bosnia after a war that erupted in 1992 with the collapse of Yugoslavia. The number of suspects could eventually be over 600 as more records from Bosnia become available, the newspaper reported. “The more we dig, the more documents we find,” Immigration and Customs Enforcement historian Michael MacQueen, who has led many of the agency’s war crimes investigations, told the Times. Many of the Bosnian suspects were former soldiers and they include a Virginia soccer coach, an Ohio metal worker and four Las Vegas hotel casino workers, the newspaper said. Some are now US citizens, it said.
