A single-vehicle crash occurred in Jefferson County along I-64 yesterday afternoon.  35-year-old Shawn Maturo of Kentucky was towing a trailer while traveling westbound along Interstate 64, near mile marker 83.  For an unknown reason, the trailer came off of the hitch and caused the vehicle to swerve out-of-control.  Shawn over-corrected once he went into the median and overturned become coming to a rest on the right side of the interstate.  The vehicle and the trailer both suffered major damage and had to be towed from the scene.  Shawn suffered major injuries from the accident and had to be airlifted to a St. Louis hospital.  His passengers, including 35-year-old Amanda Maturo and 4 minors, all from Kentucky, were uninjured.  No charges were issued.
