Emergency crews responded early Friday morning to an incident in which a person had been run over by a vehicle, according to Lawrence Police spokeswoman Kim Murphree.

Murphree said officers responded about 1:20 a.m. to the intersection of North Seventh and Ash streets, where they found a man — identified as 22-year-old Ernest Davis — lying face down in the roadway.

The 21-year-old driver of a Dodge Stratus told police that he was driving westbound on Ash Street when he saw Davis lying in the road. The driver, however, was unable to stop in time and the car ran over Davis.

Davis was transported to Stormont Vail Hospital in Topeka with critical injuries.

The incident is still under investigation, Murphree said.
