A Wynona woman died Monday night following a one-car accident on an Osage County road near State Highway 99.

Rhoda Marie Dingman, 46, suffered massive injuries in the mishap, which occurred around 9:42 p.m on County Road 5013, approximately three-tenths of a mile north of SH 99, the Oklahoma Highway Patrol reported.

An OHP investigator said Dingman was the lone occupant of a 2005 Chevrolet Equinox that was traveling south on the gravel road.

For an unknown resason, the vehicle left the roadway on the left and entered into a broadslide before striking a tree on passenger side. The car continued for a one-quarter roll up the tree and then came back down to rest on all four wheels, the report added.

The woman was pinned in the vehicle for approximately 20 minutes, the OHP said. She expired after being taken by Hominy EMS ambulance to Pawhuska Hospital, according to the report.

Cause of accident was listed as “unsafe speed for type of roadway.” The driver/victim was not wearing a seatbelt and the vehicle’s airbags did not deploy, the OHP report said.

Trooper Armstrong of the Pawnee/Osage county detachment of OHP Troop K compiled the report information.

Assistance at the crash scene was provided by Wynona police and fire department personnel, as well as by Osage County Sheriff’s deputies, Osage Nation Tribal Police and Hominy EMS.
