OKLAHOMA - The accident report is five pages long, and it details information found from the vehicles data recorder.
The recorder shows three different things: how fast the vehicle was going five seconds before impact, if McClendon tried to stop and if he was wearing a seat-belt.
According to the vehicle data recorder, the vehicle veered off the road and to the left about 63 yards before it hit the bridge.
It was traveling about 88 or 89 miles an hour.
Police said, at the time of impact, McClendon's foot was almost completely off the gas pedal, and he crashed into the bridge at a terrifying speed of 78 miles an hour.
"There were no significant skid marks or tire marks as he went left of center," said Chief Bill Citty, Oklahoma City Police Department.
The data crash recorder also indicated the use of the vehicles brakes and they were functioning at the time of the crash.
"He did brake several times, tapped his brake several times," Citty said. "The box shows that he tapped his brakes but not enough to really consider breakage. It didn't really slow the vehicle down. The vehicle maintained speed even when he was touching the brake."
The data recorder also confirmed McClendon was not wearing a seat-belt.
Initial reports said he died from blunt force trauma.
"The medical medical examiner stated, preliminary, there doesn't appear to be any type of medical episode," Citty said.
There are now more pieces to the puzzle, but Citty said he won't speculate as to whether the crash was a suicide.
"We don't know what was going through his mind," he said. "We don't know what was going on in the cabin of the vehicle."
For now, police are continuing their investigation, talking to family and friends.
They are checking emails, texts and cell phone records trying to piece together a timeline before the crash - longer than the short five seconds they were able to get from the black box.
