Is this after cleanup? There's almost zero wreckage and if it was at takeoff it shouldn't have enough speed or descent angle to atomize.

Almost certainly no cleanup before that photo was taken. The accident occurred at 1120, and the article was "last updated" at 1302, 1 hour 42 minutes is not enough time to cleanup a site like that when they still have to do the accident investigation.

It would likely have had full fuel tanks so that's probably why we can see little debris.

There was a post crash fire, and that would be a lot of fuel burning.

Look at the fairfield airshow crash, there nothing left but a bit of the tail.
