IDAHO FALLS, Idaho (AP) — Eastern Idaho authorities have identified the Montana woman who died in an all-terrain vehicle crash at the St. Anthony Sand Dunes.

The Fremont County Sheriff's Office tells the Post Register in a story on Monday that 32-year-old Sheree Eaton of Belgrade, Montana, died in the crash on Friday. Sheriff Len Humphries says Eaton and her 8-year-old son were riding along the dunes when the ATV rolled.

Fremont County Coroner Bonnie Burlage says Eaton sustained a broken neck in the crash and likely died almost instantly. Humphries says no one witnessed the crash, which was discovered by Eaton's husband and daughter.
