At the risk of being shot down for speculating too soon, I am going to jump in and say what I think from footage of the accident aircraft. I am always open to criticism if I am wrong.
1. No post crash fire.
2. The aircraft was in a left hand bank when it crashed.
3. The right wing aileron is in the up position suggesting the that PF was trying to correct the left hand bank
4, The elevator is is an up position suggesting that PF was trying to pull up.
5. The rudder looks to be fairly center.
6. Unfortunately, we can't see the propellers, but I don't see any gouge marks anywhere on the runway or near it which might have been caused by a spinning propeller.
The evidence that I have cited above suggests to me that they ran out of fuel some time during the approach and they stalled.
Of course, I may be completely wrong.
Edit: Another thing I failed to mention: What looks like full flaps and gear down would have caused a stall very quickly.
