Two men injured in a two-car accident Sunday evening south of Clinton Lake are in critical condition but stable, according to Jacob Moomau, a trooper with the Kansas Highway Patrol.

According to a KHP accident report, both cars were eastbound on North 950 Road near East 850 Road when the driver of a Honda Civic rear-ended a Ford Focus, causing both vehicles to lose control.

The Civic overturned multiple times and landed on its roof off to the side of the road. The Focus came to rest upright in a ditch to the south.

The driver of the Focus was Teodulo Bernardino-Ortiz, according to the KHP report. Sgt. Donn Dunkle of the Douglas County Sheriff’s Office said Sunday that Bernardino-Ortiz refused medical treatment at the scene.

Bernardino-Ortiz, 26, of Lawrence, was arrested at the scene on suspicion of driving while intoxicated, according to the Douglas County booking logs. He was released from the Douglas County jail early Monday on a $250 bond.

Carmelo Altamirano-Cantu, who was driving the Civic, according to the KHP report, was taken by Lifestar helicopter Sunday to Kansas University Hospital. Erick Quiroz-Estrada, the passenger in the Civic, was taken by ambulance to Stormont-Vail hospital in Topeka. Both were in critical condition but stable Monday evening, Moomau said.

“Based on the observations we made at the scene, both drivers were impaired, but to what extent we do not know,” Moomau said.

Dunkle said Sunday that he believed alcohol and speed were both factors in the accident.
