Harrison County District Court Judge Kathleen Kilnoski ruled today that Cody Metzker-Madsen,18, was not guilty by reason of insanity in the murder of his 5-year-old foster brother in Logan, Iowa.
During his trial, Metzker-Madsen admitted to killing Dominic Elkins on Aug. 31, 2013, but claimed he believed the young child was a "goblin," noted KMTV (video below).
Metzker-Madsen and Elkins lived in the same foster home and were playing a Roman mythology game in the backyard.
Metzker-Madsen claimed that he thought he was using a fake sword and a real brick to destroy a goblin when in reality he was beating and drowning Elkins, reports CBS News.
"I loved the little guy, I would never hurt him," Metzker-Madsen stated in court. "Not even a hair on his fricken' little head."
"Now, I know I did hurt Dominic," Metzker-Madsen added later. When asked if he killed the small boy, Metzker-Madsen replied, "Yes."
"I started pushing his head into the water as I was hitting him with the brick,” Metzker-Madsen stated.
Prosecutors claimed that Metzker-Madsen was mad at the boy for not playing the game his way and had a history of violence.
After the judge's ruling, Barbara Kunch, the biological mother of Elkins, burst into tears and ran out of the courtroom, according to the Des Moines Register.
Metzker-Madsen was taken to the Iowa Medical and Classification Center by two sheriff's deputies this morning.
Metzker-Madsen will stay in the facility for psychiatric evaluation and observation. He won't be released until officials believe he's no longer a threat.
