Bobby died in a car accident on the same bridge that his mother had died on just one year prior to his death. He was only 17.
The story about Bobby's death on a bridge where his mother had died only a year before is just one of those Hollywood myths.
It is true that he died in a car accident at an intersection by a bridge in Keystone South Dakota but he was nearly 22 years old.
His mother had passed two years before him but it was due to a heart attack and she died in her home.
