direction of flight
I'm thinking they were still northbound, based on the wreckage trail. Light stuff stays put heavier stuff moves in the direction of the flight and it sort of looks like engine components are to the left in the picture. Perhaps they were visual and circling, Captain flying from the left seat so he widens to the right to keep the runway in sight. In low vis he may not have had good visual detail of the terrain and flew right into in. The relatively long wreckage trail, and the fact there were survivors suggest controlled flight into terrain at relatively shallow impact angle.
