Rio de Janeiro investigators suspect that the wife of Greece's ambassador to Brazil was murdered at the behest of his wife and a police officer with whom she was romantically involved, Globo TV reported Friday, citing police sources. Greek Ambassador Kyriakos Amiridis, 59, had been missing since Monday night, but his Brazilian wife, Françoise, reported his absence to police on Wednesday. Police told Globo TV they believe the wife, Françoise, and the police officer, Sergio Moreira, arranged and possibly carried out the killing of Amiridis in a home where the diplomat and his wife were staying in a poor section in the northern suburb of Rio.
