The Highway Patrol is investigating the stabbing of a semi-truck driver Wednesday night in Medina County.  It happened on I-76, near Akron Road, after the semi driver reportedly pulled over onto the side of the highway.  The victim was taken to the hospital with non-life-threatening injuries.  According to the Highway Patrol, once the driver was taken to the hospital his story changed about being robbed and stabbed, and instead said he made the story up about two men robbing him. Troopers have no information as to why the truck driver lied about the situation.
