The drow slips back down the tree, grabbing the ranger's bow, and heads back to the camp.  Taking the other bodies that were her kills, and stuffing them in the bag along the way.  She goes right to the spot where the three who rushed her were, and begins to lay the bodies out.  The ranger first, stripping her of any weapons, before tieing her up, taking her time to do so, making sure she's secure in the ropes, before searching the other bodies for whatever valuable items they may have had, along with coin and weaponry.
