A 24-year-old Olathe man was listed in serious condition Monday afternoon after he was injured early Sunday morning in a single-vehicle accident in southeastern Douglas County, according to a spokesman for Kansas University Hospital in Kansas City, Kan.

The Douglas County Sheriff’s Office has identified the injured man as Blaine Angell, and Wellsville police officers have said they were pursuing Angell’s vehicle before it rolled over at 1:30 a.m. in the 200 section of East 2300 Road, where the road turns from pavement to gravel.

Wellsville officers had initially tried to stop Angell in a 2007 Mini Cooper before he crashed while headed north in southeastern Douglas County. Angell, who was ejected from the car during the crash, was flown to KU Hospital by helicopter ambulance, and sheriff’s officers said they suspect alcohol contributed to the wreck.
