The Coup

Four days ago, the vaults of the casino were raided, with a large part of their content disappearing. It was a clean hit carried out by professionals. The 3special Operations Group (G3O) of the national police managed to arrest four suspects as they were about to leave the country. All evidence points to them being responsible for the great theft, but only a few worthless pieces of evidence have been found. The suspects have been detained for over 70 hours, and within 75 minutes, they will have to be released if no evidence against them is found to prove them inevitably guilty of the great casino robbery. You belong to the G3O and you must prove that they are guilty before time runs out. Are you ready?
