My thoughts to all the family and friends of those involved. I was over the area at FL380 and heard it all unfold on 121.5. Rough running engine could be heard in background followed by a call that they had smoke in cockpit followed by engine failure. I was listening ready to pass on a message that they were down safely but did not hear anything and was just hoping as we flew north then we were out of range to hear. Was so sad to hear the news.
