Logan, IA (A-P) A western Iowa teenager who claimed he killed his 5-year-old foster brother because he thought the child was a goblin has been found not guilty by reason of insanity. Harrison County District Court Judge Kathleen Kilnoski issued her ruling today (Friday) in the bench trial of Cody Metzker-Madsen, who was charged with first-degree murder in the August 2013 death of Dominic Elkins, of Atlantic. Metzker-Madsen will remain in the Harrison County Jail until he can be transferred to the Iowa Medical and Classification Center in Coralville, for evaluation.

Authorities say Metzker-Madsen killed Dominic while the two played outside of their home in western Iowa. Metzker-Madsen was 17 when the boy’s body was found at the bottom of a ravine.  Metzker-Madsen told the judge during the trial that he believed he was in a fantasy world and thought he was killing a goblin instead of Dominic.
