Four people were injured in a single-vehicle rollover accident Friday, March 15, 2019 approximately one mile west of State HIghway 3W on State Highway 59A.

A Piedmont man who was injured in a March 15 wreck west of Ada has died.

Ulmar Nix, 84, died of his injuries March 28, the Oklahoma Highway Patrol said Monday.

Nix was riding in a 2002 Chevrolet pickup truck driven by Piedmont resident Loreta Nix, who was eastbound on state Highway 59A about 15 miles west of Ada. Loreta Nix took evasive action to avoid a black SUV that was westbound in her lane, and she went off the road to the right.

The pickup truck went back onto the road and crossed the center line, according to the OHP.

The Nixes were towing a trailer, which jackknifed and caused the truck to roll.

Loreta Nix was taken to OU Medical Center in Oklahoma City, where she was admitted in stable condition with a head injury.

Two passengers – Piedmont residents Jacinto and Belen Flores — were ejected from the pickup truck when it rolled over. Jacinto Flores, 73, was taken to Mercy Hospital Ada, where he was treated and released.

Belen Flores, 62, was airlifted to OU Medical Center, where she was admitted in stable condition with head and internal trunk injuires.

Ah OHP report said Loreta Nix’s condition was apparently normal at the time of the accident. The report also said that her efforts to avoid the SUV had caused the accident.

The pickup truck was equipped with seat belts, and Loreta Nix and a front-seat passenger were wearing them, according to the OHP. The truck was also outfitted with airbags, which did not deploy.
