In the Life News video that Kulvertukas posted, there was also a large part of missing fuselage visible. On the video a cargo bay under floor structure is visible and more than half of ceiling of the right side. It is unclear if there is one more piece between tail section missing or not. Probably there is.
On the roof it seems to be a aluminium skin ripping pattern to be visible. No soot or fire damage visible.
So, what happened first? tail was broken off or something happened to the fuselage between wings and tail?
