A 43-year-old Kyle, South Dakota man, Marlin Iron Crow, is facing life behind bars after being indicted on federal second degree murder charges stemming from a deadly assault in Porcupine. The indictment, handed down November 16, 2016, accuses Iron Crow of killing another man by attacking him in the head during a violent confrontation.
Iron Crow appeared before U.S. Magistrate Judge Daneta Wollmann on November 22, 2016, where he formally pleaded not guilty to the charge. The case, prosecuted by Assistant U.S. Attorney Megan Poppen, is being handled by the U.S. Attorney’s Office for the District of South Dakota. Despite the plea, the government alleges the attack was fatal and deliberate, occurring on tribal land under federal jurisdiction.
If convicted, Iron Crow faces a maximum penalty of up to life in federal custody, a $250,000 fine, five years of supervised release, and a mandatory $100 payment to the Federal Crime Victims Fund. The court may also impose restitution, though specifics have not yet been determined. The severity of the sentence reflects the gravity of the crime under federal guidelines.
The investigation was led by a joint task force involving the Bureau of Indian Affairs, Office of Justice Services, the Oglala Sioux Tribe Department of Public Safety, and the Federal Bureau of Investigation. Their collaboration underscores the complex jurisdictional landscape of violent crimes on tribal lands, where federal authority often intersects with tribal sovereignty.
Following his arraignment, Iron Crow was remanded into the custody of the U.S. Marshals Service, where he remains pending trial. No trial date has been set as of the latest court records, though pre-trial motions and discovery are expected to move forward in the coming weeks.
The charge against Marlin Iron Crow is merely an accusation, and he is presumed innocent until proven guilty beyond a reasonable doubt in a court of law. The DOJ and federal prosecutors have not released the victim’s name, pending family notification and further investigative protocols.
