A Canadian GP marshal died on Sunday evening after being hit by a tow truck that was carrying the Sauber of Esteban Gutierrez back to the pits.
An FIA statement said: “The recovery vehicle had lifted the car to return it to the pits and while doing this the worker dropped his radio and attempted to pick it up. As he did this, he stumbled and was hit and run over by the recovery vehicle.
“The worker was transported via helicopter to Sacre-Coeur Hospital where he was treated by the traumatology department of Dr Ronald Denis, Deputy Chief Medical Officer and Dr Jacques Bouchard, Chief Medical Officer of the Grand Prix. Unfortunately, the worker succumbed to his injuries at the hospital.”

Such a tragedy. Without them there wouldn’t be any racing, they’re the unsung heroes of the sport. My thoughts goes to his family and all the heroes around the world that volunteer as marshals.
