Authorities investigating March 4 death that took place in Saint Stephens area

(Fremont County, WY) – The FBI and the Wind River Police Police Department/Bureau of Indian Affairs (BIA) are investigating the death of a female subject that took place during an incident occurring on March 4, 2025, in the Saint Stephens/Riverton area, according to Vikki Migoya, the Public Affairs Officer for the FBI Denver Field Office.

“Wind River Police/BIA notified FBI of an incident early on March 4,” the FBI Denver Field Office shared in a statement sent to County 10. “A female who was involved has since passed away. Part of our investigation involved a scene near the 900 block of Rendezvous Road. That location was processed by FBI along with BIA and Wyoming Highway Patrol.”

“The investigation into the incident is ongoing,” the FBI statement goes on to inform. “At this point it is accurate to call it a death investigation. The coroner will determine a cause and manner of death. If information about the female is officially released, it will come from the coroner.”

County 10 has submitted for a public docket from the Coroner’s Office, which will be made available in the coming weeks.
