This is what i heard. Driver had backed up to a spring loaded dock, had to pull out the trailer to close the door. Upon exiting the truck he forgot to set the brakes, went inside the building, jumped from the dock to the trailer (3 feet) pulled the door down, trailer then started rolling back and then pinned him against the dock. Sad thing, the guy was 64 years old and going to retire soon. Driver was out of the NIL (wilson, NC) terminal. Be safe out there guys.
