Henrietta Dodd shoots Johnny holding the gun in her right hand. Sheriff Bannermann emerges from the bathroom and shoots Henrietta. The film switches to slow motion as she is shot and stretches both of her arms out to the sides as she falls. When she lands, her left hand is resting next to the railing of the stairs and is covered in blood. At no time did her hand come in contact with her wound or get any blood splattered onto it.
