A motorcyclist was killed Saturday when it was struck by a passenger vehicle on Lake Mary Road at the intersection of Stoneman Lake Road. Mormon Lake Fire crews and Coconino County Sheriff’s deputies responded to the scene. Crews found the motorcyclist unresponsive and had extensive injuries. They began treatment immediately, but the person was later pronounced dead at the scene. The driver of the passenger vehicle was transported to Flagstaff Medical Center for treatment. CCSO officials say the initial investigation indicates that the motorcycle was headed south on Lake Mary Road, when the passenger vehicle turned northbound onto the road from Stoneman Lake Road and hit the motorcycle. The accident remains under investigation. The wreck caused the road to be closed for four-and-a-half hours.
