Troopers said there was no evidence that Diaz hit the brakes.
“We don't know if he may have had a medical condition. There's no evidence to show that he was out of control or driving erratic prior to leaving the roadway and striking the tree,” said GSP officer Tim Nichols.
Diaz died at the scene. Paramedics flew his daughter, 28-year-old Ashley Deegan to the hospital. Her nine-month-old son also survived.
