OSKALOOSA, IOWA (AP) -- The lawyers for an Oskaloosa man accused of using a medieval ax to kill another man have filed notice that they may seek a defense of diminished capacity or insanity.
Bradley Arterburn is charged with first-degree murder in the June death of 58-year-old Robert Horovitz, of Davenport.
The Public Defender's Office has filed a rule request which covers several defenses, including insanity, diminished capacity, intoxication and self-defense.
Oskaloosa Police say Arterburn used a "medieval-style" battle ax to attack Horovitz at the home Arterburn shared with his mother in Oskaloosa.
The trial in this case is set for December 6th in Mahaska County Superior Court.
