Fargo Man Pleads Guilty to Second Degree Murder and Voluntary Manslaughter in Indian Country

ALBUQUERQUE, N.M. – Alexander M.M. Uballez, United States Attorney for the District of New Mexico, and Raul Bujanda, Special Agent in Charge of the Federal Bureau of Investigation’s Albuquerque Field Office, announced that Shilo Aaron Oldrock, 30, and an enrolled member of the Spirit Lake Sioux Tribe, pled guilty in federal court to second degree murder and voluntary manslaughter. Oldrock will remain in custody pending sentencing which has not been scheduled.

According to court documents, on January 29, 2021, Oldrock and John Doe 1 attacked and killed John Doe 2. Later, on October 10, 2021, Oldrock attacked and killed John Doe 1 before decapitating his head with an axe and throwing it in a woodstove inside John Doe 1’s residence. Oldrock did so because he believed John Doe would harm him in order to cover up John Doe 2’s murder. Oldrock also believed that John Doe 1 had killed Oldrock’s grandmother.

At sentencing, Oldrock faces up to 35 years in prison.

John Doe 2’s family reported him missing and he was added to the FBI’s List of Native Americans Verified as Missing Throughout New Mexico and the Navajo Nation. The List is the first of its kind in the nation and was created in an effort to improve the reporting of missing persons throughout New Mexico and the Navajo Nation. Partners involved in the project include the U.S. Attorney’s Office, Bureau of Indian Affairs Office of Justice Services, New Mexico’s Missing and Murdered Indigenous Women and Relatives (MMIWR) Task Force, New Mexico Attorney General’s Office, New Mexico Department of Public Safety, New Mexico Department of Indian Affairs, Bernalillo County District Attorney’s Office, and the City of Albuquerque Office of Equity and Inclusion. The FBI also receives information and support from the Navajo Nation, Native American pueblos, and local law enforcement.

The list is updated monthly and can be found at fbi.gov/mmip.

The FBI is seeking public assistance and information on the cases. If you have information concerning any of the cases, please contact your local FBI office, the nearest American Embassy or Consulate, or submit a tip online at tips.fbi.gov.

The FBI Albuquerque Field Office investigated this case with assistance from the Navajo Department of Criminal Investigations and the Gallup Police Department. Assistant United States Attorney Nicholas J. Marshall is prosecuting the case.
