Patrick requested the people working in higher ranks at 'The Eminent club' to share their employees profile as it was needed for the investigation of a case and informed them that the real Robert Nowak was already dead and the one working there is a fake.
The higher authority at The Eminent club was shocked to know this information as they never encountered anything like this in their life, they hired one person and let some other person work there, they were shocked but they promised the police department that they will cooperate with them and provided all the information, fingerprints, documents they had on Robert Nowak to the police.
The fingerprints were sent through a system so it didn't take much time.
