The Concho Kid: A Short Western (Unabridged‪)‬

When 16-year-old Benjamin Bradley kills his step-daddy, he is transformed into a ruthless killer, seemingly without a conscience. The sheriff forces him to leave town or stand trial for murder. He then shoots the sheriff in the back and kills him. Killing seems to come so easy for him that he kills the livery stable owner, steals a horse, and rides out of town. He's not only a bad guy. He's the worst of the worse. He's a cold-blooded killer. He kills indiscriminately. No one is safe when he goes on a killing rampage.
