Deputies determined that a 50 year old Albion, Indiana man was driving his motorcycle south on M-66 when a semi pulled into the intersection, trying to turn north, and the two vehicles collided.

The motorcyclist was flown by Samaritan Air Care to Bronson Methodist Hospital in Kalamazoo and is listed in critical condition. The semi driver, a 60 year old Mendon man, was not injured. Deputies say the motorcycle driver was not wearing a helmet.

The matter is still under investigation.
