A Sisseton man has pleaded guilty to a voluntary manslaughter to a minor charge in a case that stems back to 1992. New evidence implicated 57-year old Jay Adams Jr., in the death. The release states the case is part of the Department of Justice’s newly created Missing or Murdered Indigenous Persons (MMIP) Regional Outreach Program, “which aims to aid in the prevention and response to missing or murdered Indigenous people through the resolution of MMIP cases and communication, coordination, and collaboration with federal, Tribal, state, and local partners.”

In September 1992, in Roberts County, Adams killed a minor victim in the heat of passion by inflicting fatal blunt-force trauma to her head. Adams has signed documents admitting he used violent force to inflict the injury upon the victim. Adams did not seek medical attention for the victim and, later the same day, discovered she had died. Adams feigned ignorance as to the cause of the victim’s injury.

A presentence investigation was ordered, and a sentencing date was set for June 3 in Aberdeen. Adams was ordered to self-surrender to U.S. Marshal’s custody by December 11th.
