The woman who killed four people when she plowed her car into a crowd at Oklahoma State University's homecoming parade wasn't found to be intoxicated, according to court documents filed Thursday.
Adacia Chambers, 25, has been charged with four counts of murder and 46 counts of felony assault after the Oct. 24 tragedy that left a beloved former professor, his wife, an exchange student and a 2-year-old boy dead. Forty-six people were also injured.
Chambers' attorney, Tony Coleman, has said that he doesn't believe his client was under the influence of alcohol or drugs, but instead likely "suffers from a mental illness."
An application for psychology and crash reconstruction experts filed by Chambers' lawyer in Payne County Court revealed that Chambers' blood alcohol level was just .01 when her blood was drawn immediately after the crash.
A blood alcohol level of .08 in Oklahoma results in a charge of driving under the influence, which Chambers was originally arrested for because police suspected she was impaired.
The court document makes no mention of Chambers' drug toxicology results.
The documents filed Thursday said that Chambers underwent two psychological evaluations — one on Oct. 26 and a second on Nov. 17. The application asked that the court allow independent experts for the defense and the prosecution to "explain how the defendant can present differently during the evaluation process."

"If the defendant cannot understand the evidence, there is no way they can properly confront or cross examine the evidence, which is their constitutional right," the application said.
The defense also asked for crash reconstruction experts to testify.
Chambers is being held on $1 million bond in Payne County jail, according to jail records. She could spend at least 40 years in prison if convicted on the murder counts.
