I think that the location of the toddlers body away from the crash site has been overstated by media outlets and its actually nearer the main crash site than 20 miles. There was only one ‘event’ that was indicated by the FR24 data.
For what it is worth, I now unfortunately think that it will turn out to be a small to medium sized bomb in the aft cargo bay, resulting in the structural failure and disintegration of the rear fuselage (note the pictures of the ‘peeled’ roof of the rear fuselage without fire damage and seats still attached to structural bearings) and detachment of the tail with damage from disintegrated fuselage parts.
The front fuselage and wings unable to fly on, lost horizontal speed and fell near vertically rotating and pitching as it went. At some point prior to impact ignited (causing sooting to engine intake), with an additional fireball on the ground.
