PORTLAND, Maine — Maine’s highest court has upheld the convictions and sentence of a Newcastle man and a former girlfriend.

The Maine Supreme Judicial Court on Tuesday rejected John A. Okie’s appeal of his convictions and 60-year sentence for the 2007 bludgeoning death of 19-year-old Alexandra “Aleigh” Mills and the stabbing death of his father, John S. Okie, six days later.

Okie’s lawyer argued that the judge at Okie’s trial should have told jurors what would have happened had they found him not criminally responsible by reason of insanity. The appeal further argued that the judge improperly calculated Okie’s sentence.

Supreme court justices rejected the appeal in a unanimous decision.
