Hawthorn assistant coach Brett Ratten is mourning the death of his 16-year-old son Cooper, who died in a car crash in the early hours of Sunday morning.
Cooper, along with two teammates from his AFL team, spent the hours before the crash at a function put on by his AFL club. It is alleged that the trio took keys belonging to a parent before driving away in foggy conditions.
Cooper Rennan was in the back seat of a VW Tiguan with two of his friends. It is alleged that the car was traveling in excess of 100km/hr, before failing to take a turn and rolling off the road.
Cooper, who was not wearing a seatbelt, was thrown 40 metres from the vehicle.
