Alcohol is suspected of being a factor in a one-vehicle motorcycle accident late Tuesday being investigated by the Norwalk post of the state Highway Patrol.
William Avsec, 51, of Ashland, was driving a 2011 Harley-Davidson motorcycle south on Butler Road, which is closed for construction. Troopers said he hit an uneven portion of pavement, causing him to lose control of the bike.
The bike overturned and stopped in a ditch, ejecting Avsec, who was wearing eye protection, but didn't have a helmet on, troopers said.
A LifeFlight helicopter transported Avsec to MetroHealth Medical Center in Cleveland. Hospital spokeswoman Tina Shaerban-Arundel said he was in critical condition as of Wednesday morning.
The serious injury crash happened about 11:07 p.m. on Butler Road near U.S. 20. The Wakeman Fire District, Citizens Ambulance and White's Towing assisted troopers at the scene.
Troopers said they smelled alcohol at the scene, and blood samples were taken for testing. Those test results are pending.
The crash remains under investigation.
