Pretty suggestive of forceful breakup when composite panels are sheared this way.
Suggestive yes. This is the interior wall of the cabin. If you look closely you can see the snap-ons on the lower parts of the wall. These are for easy removal during various in-depth checks of the aircraft.
The lower part of the interior wall seems pretty intact, a little crushed from the above maybe. What this tells us is not much though, unless seen in context with other parts of the adjacent structures.
