The death toll in a multi-vehicle crash on Interstate 40 that occurred last week in Seminole County has risen to three.

As reported in the April 27 edition of the Seminole Producer, 43-year-old Todd Cahill of Shawnee was killed Sunday, April 25 as he allegedly drove the wrong way on the interstate and struck several vehicles.

On Sunday, the Oklahoma Highway Patrol (OHP) reported that Klint Impson, 41, and Katheryn Impson, 39, both of Ft. Gibson, had died from injuries they sustained in the wreck.

According to the OHP, Cahill was driving a Jeep Liberty eastbound in the westbound lanes of the interstate and hit three vehicles. He was ejected almost 100 feet from the Jeep in the third collision and was pronounced dead at the scene.

Cahill’s vehicle initially hit a Ford Expedition then continued eastbound, striking a Kia SUV driven by Klint Impson, pinning all occupants, including two juveniles, inside for approximately 45 minutes. All four were transported to the OU Medical Center after being extricated by the Strother Fire Department. The driver of the Expedition was uninjured.

Cahill then hit a Dodge Ram pickup driven by Christopher Lantz, 33, of Oklahoma City in the outside lane, causing Cahill’s vehicle to overturn and eject him. The pickup in turn struck a BMW driven by Remzi Derti, 66, of Denison, Texas. Neither Lantz nor Derti were injured.

The crash occurred near mile marker 197, about three miles west of the Seminole/ Prague exit. The westbound lanes of the interstate were shut down for several hours and drivers were detoured at US-377/SH-99 to SH-99A west to SH-9A then north to I-40.

According to a press release from the Oklahoma National Guard, six soldiers from the 545th Brigade Engineer Battalion and one soldier from the 1st Battalion, 179th Infantry Regiment, were returning to Norman after completing several days of training at Fort Chaffee, Arkansas, when they came upon the accident scene.
