Five people died Saturday night in a head-on crash south of Riverton on the Wind River Reservation, and Fremont County Coroner Mark Stratmoen released the victims' names Wednesday.

Elizabeth "Betty" Ridgley, 67, was the only person killed in one of the vehicles. Three other occupants were injured, but survived the crash.

In the other vehicle were 25-year-old Whitney SunRhodes, 25-year-old Kristen SunRhodes, 54-year-old Derrald Antelope and 54-year-old Sandra Lucero.

The cause of death for all five Wyoming residents is blunt force trauma as a result of the crash. The manner of death has not yet been decided, pending toxicology results and investigators' findings.

The three survivors were taken to a hospital, where they were listed in serious but stable condition Tuesday.

Stratmoen says the Federal Bureau of Investigation, Bureau of Indian Affairs and Wyoming Highway Patrol are the agencies leading the investigation.

The Fremont County Coroner's Office will not release further information until public records dockets are issued after toxicology results are received.
