A two-month investigation by the Oklahoma City Police Department found no evidence of suicide in the March 2 car crash that killed Oklahoma City businessman Aubrey McClendon, the police confirmed Tuesday.

A report has not been released, but the two-month investigation has been completed, spokesman Capt. Paco Balderrama told The Oklahoman on Tuesday.

"That investigation involved homicide detectives looking into the circumstances that led up to his death," Balderrama said. "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."

Balderrama said the investigation was thorough and looked into every possibility.
