At about 0:05:30, just as the "I-shot-cain" brothers run out to meet the rest of the celebrating townsmen, and as they are dragging the second dead body from right to left across the scene, you can clearly see the first dead bank robber (on the left of the scene) lying on the ground, but sitting up watching the scene take place.
Ben inexplicably regains his shoes between getting the second horse and riding into the next town.
