SIOUX FALLS S.D. (KELO) There are more details on the disappearance and discovery of what law enforcement believe to be the remains of Matthew Marshall.

A release from the South Dakota Attorney General’s office says a search conducted in Fall River County has led to the discovery of human remains which are thought to be those of Matthew Marshall of Hot Springs, who disappeared from that area in July 2024.

“While positive identification is still pending, the discovery of personal belongings in the area indicate it is likely Matthew,” Attorney General Marty Jackley said in a news release. The Medicine Wheel Ride organization posted on Friday about Marshall’s remains being found.

Marshall was last seen on July 24, 2024 in Hot Springs. He was reported missing by his family Aug. 4, 2024. Multiple searches have been conducted by local law enforcement and partner agencies during the last 10 months.

The human remains were found May 29, 2025 by Custer County Search and Rescue. The AG’s office said the death investigation is ongoing but does not appear to be foul play.

Agencies involved in the search were the South Dakota Division of Criminal Investigation (DCI), the Attorney General’s Murdered and Missing Indigenous Persons Program (MMIP), Hot Springs Police Department, Fall River County Sheriff’s Office, Custer County Search and Rescue, and BIA Missing Murdered Unit.
