The grieving teen girlfriend of Cooper Ratten, the son of AFL legend Brett Ratten, has vowed she will never forgive the driver of the car involved in the accident that claimed the 16-year-old's life.

Ringwood teenager Cooper Ratten, 16, was thrown from the back seat of the car after it veered off the road and rolled at Yarra Glen, northeast of Melbourne, just after 3am on Sunday.

Jasmine Williams said she felt 'disgusted' by the 'reckless driving' of the 17-year-old driver who police say miraculously survived the deadly crash.





"I will never feel sorry for you hope it sticks with you forever," she posted on Facebook before later deleting.

She admitted Cooper and his two Yarra Glenn Football Club teammates were all at fault for getting in the car amid suspicious of alcohol and drug use but stopped short of blaming Cooper for the accident.

"He was not in control and had no chance of stopping it, whereas (the driver) did," she said.

On Sunday, she posted an emotional tribute to her boyfriend.

"My whole world has been turned upside down but I have nothing to say but good things about you Cooper," she posted to Facebook.

"I can't believe it's true and I refuse to say rest in peace because I know you're still right here next to me.

"The love I have for you will never change only get stronger and all I could wish for right now is to be up there with you but I know you wouldn't want that."







It followed the heartfelt tribute from his father, AFL legend and Hawthorn assistant coach Brett Ratten.

“We love you so much and we will miss you forever," the message said.

"You will be with us every minute of every day.

“You had so much potential and ability in the things you set your mind to. You have been taken way too soon and we will miss your smile, your laugh and all your cheekiness.

“These memories will last forever. I wish I could kiss you, hug you and hold you tight. I love you, my son. We love you so much always and forever.”

Detective Sergeant David Yeoman says high speed, in excess of 100km/h, is an obvious factor and police are considering whether the car was stolen.

Investigators will also look at whether drugs and alcohol contributed to the tragedy, which occurred while visibility was low due to thick fog.

"I think its an absolute miracle that two people got out of that vehicle alive," Det Sgt Yeoman told reporters.

The 17-year-old Yarra Glen boy, who was in the front seat, was taken to Box Hill Hospital with minor injuries, while the 17-year-old driver, of Healesville, was taken to Maroondah Hospital.

Police will speak to the pair and lay charges if necessary, Det Sgt Yeoman said.
