Wearing a striped prison uniform, Colin Gray, 55, was breathing heavily as the sentence was delivered. The Crumbleys were each convicted of involuntary manslaughter and sentenced to 10 to 15 years in prison. He was sentenced Tuesday to life in prison without parole in the same courtroom and by the same judge as his father. Prosecutors had asked the court to sentence Colin Gray to 80 years in prison. Terry McElhannon, the grandfather of Taylor Jones, who was wounded in the attack, pointed an accusatory finger directly at Colin Gray while speaking.
