BLOOMINGTON, Ind. - The 20-year-old son of rock star John Mellencamp faces an underage drinking charge while awaiting resolution of charges that he and his brother seriously injured a man in a fight. Monroe County court records show Hud Mellencamp of Bloomington was charged July 10 with a misdemeanor count of illegal alcohol consumption. Details about the case weren't immediately available. Defense attorney Jennifer Lukemeyer did not immediately return a message from The Associated Press seeking comment Monday on the new charge and the request from prosecutors that Mellencamp's bond be revoked from his 2013 arrest.
