In December of 1987, three Carl Junction, MO teenagers - Theron Roland, James Hardy, and Ronald Clements - beat fellow teen Steven Newberry to death with baseball bats. The three claimed to be 'Satanists' and had tired of killing animals, and had been planning Newton's murder for some time. While bludgeoning Newton, the three allegedly screamed, "Sacrifice to Satan Sacrifice to Satan!" When Newton asked the boys why they were beating him, they responded, "Because it's fun!"
At the time of the killing, Hardy was an honor student and his class president.
He, Roland, and Clements are all serving life sentences.
