Thunder Bay's Traffic Unit is closing its investigation into the collision on John Street Road last week that resulted in the death of a young man. The investigation has revealed that both speed and alcohol were the major contributing factors in the collision. It has been further determined that the driver of the front-end loader was driving at slow speed, with all required lights and on the part of the road required by such a vehicle. The only charge laid is a Provincial offences ticket to the driver of the loader for failing to ensure that a slow moving vehicle sign was displayed on the back of the loader, but it's believed it wouldn't have altered the outcome of the event.
