May 26 was a fatal day for three women hit by trucks in Oklahoma.

Pawhuska residents Johnia Jean Mashunkashey, 41, and Eva Victoria Johnson, 46, were traveling north on Oklahoma 99 late Wednesday evening when their car struck two cows that had wandered onto the highway.

The driver, 50-year-old Michael Smith, stopped the 1996 Lincoln Town Car in the road a mile south of Oklahoma 11 in Osage County, where it lay disabled. The women exited the car to inspect the damage, and were joined by 73-year-old motorist Lloyd Meyer of Prue, who had stopped his 2009 Chevrolet pickup to aid the stranded car.

According to the Oklahoma Highway Patrol, an oncoming tractor-trailer struck both the women and the two vehicles on the highway. The semi, driven by 43-year-old James Allen Jaco of Del City, pinned one of the women under the vehicle for approximately 30 minutes.

Johnson and Mashunkashey were both pronounced dead at the scene of the accident by midnight Wednesday. Jaco received treatment at a nearby hospital and has been released; no other injuries were reported.

Hours later, an unrelated pedestrian accident proved fatal for Anna Evans of Tulsa. According to Officer Glen Emery, Evans was crossing the street on North Peoria Avenue to get to a bus stop when she was hit by a GMC pickup truck. 69-year-old Evans was rushed by ambulance to St. John Medical Center, and was pronounced dead later that day.

The accident report states that the victim was not crossing at a crosswalk when the pickup struck her at 8:15 a.m. Police released the pickup driver after determining that he had tried to stop prior to hitting Evans.
