It will be 30 years in prison for the man who killed a 12-year-old Independence boy in a car crash. Thirty-one-year-old Clayton Dunlap pleaded guilty to murder in connection with the death of Damian Slayton. Dunlap told the court he was high on PCP and driving on a revoked license when he caused the March 2010 crash on 71 Highway. The crash also severely injured Slayton’s mother.
