One man was transported early Sunday by LifeStar helicopter ambulance to Kansas University Hospital in Kansas City, Kan., after a single-vehicle rollover accident at 447 E. 2100 Rd., about four miles northeast of Baldwin City.

A nursing supervisor was unable to provide a condition update on Sunday night for Sean E. Lawrenz, 22, Lawrence.

At 12:32 a.m., emergency dispatchers received reports from a passerby that a person was trapped inside an automobile. Initial responders to the accident reported that Lawrenz had suffered critical injuries, including a head injury.

Sgt. Blake McCall of the Douglas County Sheriff’s Office said the man was driving south on East 2100 Road when, for reasons unknown to officials, his white 1994 Kia passenger vehicle veered into the ditch and through a fence.

“His vehicle rolled a couple times and probably flipped end-over-end,” McCall said. “It came to rest upside down, and he was pinned in the vehicle.”

Lawrenz was pulled from the wreckage at 12:54 a.m. McCall said emergency responders didn’t have to use the “jaws of life” for the rescue. He was unsure if Lawrenz was conscious after the accident. Douglas County Sheriff’s Office spokesman Sgt. Steve Lewis said Lawrenz was wearing a seatbelt.

He said the freezing temperatures made if difficult for emergency responders to extract Lawrenz. While a cause of the accident has yet to be determined, Lewis said alcohol is not believed to have played a part.

“You know on a gravel road, when you run off the road, it’s up for grabs,” Lewis said.

The vehicle was reportedly leaking gasoline when emergency crews responded, but no fire resulted.
