I am no expert, but wanted to share the pictures as not seen them anywhere else and may give a clue of some sort. It does look like a very similar picture to the A.A crash in 2001 when the rudder was found.
What will matter is where the vertical stabilizer was found. If it is close to other wreckage, I would think it is likely it was still attached for most of the descent. Can't read too much into this without more information.
