There were several eye witnesses who spoke to the news media but the person that was incorrectly identified and quoted by the ADN article was on the phone with Sheppard Smith on Fox News. This man was standing next to the first victim shot. You can check their news site and listen to the exchange. 

There was a person who was interviewed by another cable network who was NOT at the baggage claim area but at the one next to it who told what he was seeing to another network. There also was the woman who was texting one of the other networks from her airplane on the tarmac. 

The gunman was NOT shot by police as reported in the earlier ADN account. He put his gun down after he was done, sat down on the floor waiting to be arrested. The difference in what Les Holt reported and the what Fox eye witness reported was that it one was first hand from the scene and being heard by viewers after the gunman surrendered and after the injured were removed. He was still there when the second alarm came
