Douglas County Sheriff’s deputies are investigating after two men were critically injured in a rollover crash near Vinland early Saturday.

The vehicle left the roadway near 804 East 1900 Road and rolled, ejecting one of the men, said Sgt. Donn Dunkle with the Douglas County Sheriff’s Office. Emergency responders were dispatched to the crash at 4:28 a.m.

The vehicle then caught fire, and the other man was able to get out before it was fully engulfed in flames. In addition to the sheriff’s office, Lawrence-Douglas County Fire Medical responded to the scene.

Dunkle said the injured men were transported to Overland Park Regional Medical Center, one by ambulance and the other by LifeStar helicopter. Both men are in their early 20s, and Dunkle said their identities will not be released until Sunday or Monday.

Two dogs were also in the vehicle at the time of the crash, but suffered only minor injuries, Dunkle said. The dogs were picked up by one of the men’s neighbors.

The cause of the accident is still being investigated, Dunkle said.
