Filippo Sempio

Prosecutors in Italy have formally closed the investigation into Filippo Sempio over the killing of Chiara Poggi, with a decision on whether he will stand trial expected next. Lawyers for Alberto Stasi, the man already convicted of the murder, said the military intelligence service, the Ris, must 'assume its responsibilities' after new evidence emerged. The development reopens debate over one of Italy's most followed judicial sagas.
