A motorcycle crash left a man with massive injuries in McKinleyville Tuesday. At approximately 9:44 a.m., Michael Lafferty, age 55, of Canton, Massachusetts was driving a 2018 Ford Edge southbound on Central Avenue at Anna Sparks Way and was at a complete stop for the solid red traffic signal. David Karr, age 60, of McKinleyville, was riding a 1984 Honda V65 Magna motorcycle southbound on Central Avenue, north of Anna Sparks Way at an unknown rate of speed. The motorcycle reportedly cut into the path of a turning truck at an intersection and collided with it. As a result of the collision, Karr was ejected off the motorcycle. He came to rest on the roadway and sustained major injuries. The Arcata-Mad River Ambulance responded to the scene and transported Mr. Karr to Mad River Community Hospital for medical treatment. Mr. Karr was later transported by air to Mercy Medical Center. DUI is not a factor.
