The tail rotor support frame was completely missing. The helicopter fell like a stone. No rotation of the cabin from the main rotor torque.
it’s hard to tell from the video’s I saw. It appears that the craft split up into three pieces. I speculate that the main rotor blades separated first and then the tail rotor split off. I think they call it ‘The Jesus Nut’ that holds the main rotor to the mast in most helicopters.
As far as I know, they still haven’t found the other parts.
Bet that was a wild ride at the end.
