If the "tail" section with 100 bodies was located 1 km away from the center wing box section, then it appears the aft fuselage might be basically intact. It appears that the center wing box is missing the aft fuselage in the photographs. I don't see much of the foward fuselage attached to the wing box either. Because it appears that the center wing box (with wings attached) fell without much forward velocity, this suggests that the 738 may have broken up not long before ground impact, since the center wing box and the aft fuselage seem to be basically intact. I would think a higher altitude breakup would cause smaller pieces to be scattered farther. A mid-air breakup suggests loss of control, but this is all speculation.
This link suggested that a mid-air breakup was indeed the case.
