RCMP are looking for witnesses after a 22-year-old Edmonton man was killed in a collision early Thursday morning north of Sherwood Park.

Police say the man was riding his Kawasaki EX250 motorcycle north along Range Road 232 when a southbound truck appears to have turned into the path of the motorcycle.

The motorcycle driver was rushed to hospital via STARS Air Ambulance with serious injuries. He later died in hospital.

The driver of the truck was not injured.

An RCMP Collision Analyst and the Strathcona County RCMP continue to investigate the cause of the crash. They have ruled out speed, alcohol and road conditions as factors.

Police have not yet released the name of the deceased motorcyclist.
