My guess is he hit a car/suv with a wing and it snapped the fuselage in two...................
This is just a guess but he might have sideswiped that light pole the empennage came to rest next to.
The picture is fuzzy and the camerman was pointing in the wrong direction when it happened but it looks like he grazed the retaining wall on his right (deliberately? to avoid running out into the traffic?). It might have caromed sideways back to the left and literally wrapped itself around the light pole.
