Katz claimed that it was likely that senior figures in the Italian establishment escaped prosecution. "The problem is that the people who probably actually ordered the death of Calvi are not in the dock - but to get to those people might be very difficult indeed". Katz said that it was "probably true" that the Mafia carried out the killing, but that the gangsters suspected of the crime were either dead or missing. The verdict in the trial was not the end of the matter, since the prosecutor's office in Rome had opened a second investigation by June 2007 implicating Gelli and others.
