Chief EU Prosecutor Arrives in Kosovo for Organ Case The chief European Union prosecutor investigating claims of organ trafficking in Kosovo arrived in the region on Wednesday. American John Clint Williamson is heading a task force of prosecutors and investigators under the auspices of the European Union Rule of Law Mission in Kosovo (EULEX) to determine if reports of organ trafficking by high level Kosovo officials are true. The allegations that soldiers from the Kosovo Liberation Army (KLA) removed the organs of ethnic Serbs held in detention centers in northern Albania first surfaced in a 2010 report by European Council rapporteur Dick Marty.
