An Ohio teenager accused of killing his 14-year-old brother after an argument over Halloween candy will have a hearing Feb. 9 to determine whether his case is handled in juvenile court or the adult court system.

The 16-year-old Springfield boy was charged with aggravated murder and pleaded not guilty and not guilty by reason of insanity in Clark County Common Pleas Court.

The Springfield News-Sun reports the case is returning to juvenile court for a hearing because of a recent Ohio Supreme Court case. In that ruling, justices said automatically transferring certain juvenile cases to adult courts is unconstitutional.

Authorities allege the Springfield teen beat his brother with a baseball bat, then stabbed him. Their grandmother found the younger teen dead in bed on Oct. 31.
