Everyone that wants to comment on this accident should read the CVR that is available for public viewing. From cruise flight until intercepting the localizer there was so much mindless chatter. Very little of which was concerned with the weather conditions that they were in. A direct violation of the sterile cockpit rule below 10,000 feet.
Reading that transcript one does not get the feeling that this was a fatigued crew. This will be an interesting investigation and will cover all aspects of Colgan's operation from training, checking and adequate crew rest for their flight crews
