Historical Murders: The Unsolved Axe Murders

In 1911 a serial killer stalked the United States by train. He would sneak into a home through a window and kill entire families with the blunt end of an axe he found in or near their home. What he did in addition to murder in the homes was even more peculiar and included destroying their heads until they were unrecognizable and draping pieces of clothing over mirrors and glass to avoid the judgmental gaze of either his victims or himself. In Colorado Springs he murdered two families and has left a mystery that has lingered for over a decade, who was he and why did he hate faces?
