According to the data recorder on his vehicle, he was driving 88 mph and tapped his brakes before the impact. He had also had his gas pedal floored until 1.5 seconds before the crash, when he let up from 99% depressed to 25% depressed. Tire tracks were found at the scene, but no skid marks.
On Wednesday, the Oklahoma medical examiner's office ruled that it was an accident and not a suicide. They had conducted a two month long investigation amid wide speculation and questions surrounding his death.
"We spoke to anybody who may have had contact with him after he found out about the indictment," Oklahoma City Police Capt. Paco Balderrama told ESPN on Tuesday. "He did not leave anything that would be interpreted as a suicide note or message."
Balderrama also addressed the possibility of murder, and stated that no evidence of foul play had been found.
"That investigation involved homicide detectives looking into the circumstances that led up to his death," Balderrama told The Oklahoman. "After conducting a very thorough investigation, speaking to people who knew him and people who spoke to him prior to the accident, we found no information that would indicate anything other than a vehicular accident."
The day before the accident, the former Chesapeake Energy CEO and co-owner of the NBA's Oklahoma City Thunder, had been indicted by a federal grand jury for conspiring to rig bids for oil and natural gas leases in the northwest portion of the state.
"There was so much chatter of a cover up or something other than an accident," Balderrama said. "To put those rumors to rest, we felt it necessary" to conduct the homicide investigation.
"We may never know with 100 percent certainty, but at the conclusion of our investigation, we had no evidence to believe there were other factors or possibilities," Balderrama said.
