INDIANAPOLIS (AP) _ The Indiana attorney general is asking the state Supreme Court to decide whether a northeastern Indiana boy convicted as an adult at age 12 of killing his stepfather should receive a new trial.
 
  The attorney general's office announced Thursday it was appealing a December Indiana Court of Appeals ruling that a county judge improperly decided a week after Paul Gingerich's arrest that he could be charged as an adult.
 
  Gingerich is serving a 25-year sentence after pleading guilty to conspiracy to commit murder in the killing of 49-year-old Phillip Danner in 2010.
 
  Attorney General Greg Zoeller says he's concerned about the legal precedent of a plea agreement being overturned on appeal.
 
  Gingerich's defense attorney wasn't immediately available for comment.
