A Chandler man serving a 100 year sentence for a double murder conviction wants out of prison. A hearing is scheduled next week for Robert Wayne Grass in Warrick Superior Court. In 1988, Grass was convicted of beating, stabbing, and strangling his step mother and her mother. He then hid the bodies for several days in the back of their mobile home in Chandler. Grass was 17-years-old when the murders occurred.
