The AG in Switzerland reached the conclusion that no crime had been committed. So the investigation was closed with a Nulle Prosequi. Which is when they produced Paul Eduard Waridel, a half Turkish, half Swiss citizen, later identified as the Mastermind behind the Pizza Connection. A couple of years previously they had bailed him out of an Italian prison in Rome where he was serving a 7 years sentence for drug trafficking. The DEA (Drug Enforcement Agency) of the US had brokered a deal with him as an undercover agent, going between the Sicilian Mafia and Turkish morphine producers. The Swiss judges, however, judged that his loyalty lay entirely with the drug dealers and consequently he got a 15 year sentence.
