 Upon returning to the hospital on 12 July for a tetanus injection , Behan was arrested by five policemen and taken to their Arcidosso barracks for questioning . He did not know what was happening at first as the police had no interpreter in the barracks . He was only provided with a lawyer and interpreter 15 hours later when a magistrate from Grosseto came . Behan exercised his right not to answer questions . He was released , but was formally informed that he was under suspicion . As of 15 July 2008 he was the only suspect in the case . The police subsequently seized his car and a knife from his home , and secured a room in the house in which traces of blood were allegedly found . In addition , shoe prints found were said to have matched his footwear . Custody of his car and home ( except for the cellar ) were returned to him on 14 July by the judge overseeing the investigation .
