I can picture it hitting the stringer and being deflected upwards. If it came in at an angle through a little drywall on a side wall at the bottom of the staircase and encountered the top of a stringer, it could ricochet right up the stairway without even touching the steps.
edit: It would have to be a notched stringer with a diagonal top side.
