SIOUX FALLS (Dakota News Now) - Authorities are investigating a homicide in a small South Dakota community in which a man claiming to be the shooter contacted Dakota News Now during an alleged standoff.

The Jerauld County State’s Attorney on Sunday confirmed a single-victim homicide in Wessington Springs was under investigation, and that the suspect is in custody.

Dakota News Now staff received a phone call just before 5 a.m. Sunday from a man who identified himself as Mitch Caffee. He told one staff member that he was currently involved in a standoff with police outside of his home in Wessington Springs due to a fatal shooting and that he was the shooter.

The Jerauld County Sheriff’s office would not confirm any details at the time but confirmed later in the morning that a home near Main Street and Alene Avenue was being treated as an active crime scene.

The Dakota News Now Staff member who spoke with Caffee over the phone described him as sounding calm.

Caffee was arrested for first-degree murder, aggravated assault, kidnapping, and burglary. Caffee remains in custody on a $1 million cash-only bond.

Some streets were blocked off in Wessington Springs but were opened up around 9 a.m.

No other details have been released.
