Absolutely. There is no way a criminal can be as familiar with crime scenes as the cops. Plus, they have also seen previous staged settings. They can just smell the phonies. I am sure Scott stunk to high heaven from the first moment, even when the world was treating him as the perfect husband whose wife went missing. Yet another problem is that the would-be stager is usually under the impression that all he needs to do is avoid conviction. In fact, he has to avoid suspicion. Once you're under suspicion, it's all up, assuming the police are doing their job.
welcome Agnes. You make some great points. This guy literally did everything completely opposite to an innocent man. His behaviour was shocking!!
