STILLWATER, Okla. - A driver charged in the OSU homecoming tragedy is competent to stand trial, a judge announced Thursday.

Authorities said 25-year-old Adacia Chambers drove her car into an unmanned police motorcycle before plowing straight into the crowd of onlookers during Oklahoma State’s homecoming parade on Oct. 24.

In all, authorities said four people were killed and 46 others were injured in the crash.

Officials said 2-year-old Nash Lucas, 23-year-old Nikita Nakal, 65-year-old Dr. Marvin and Bonnie Stone were all killed in the crash.

She is officially charged with four counts of second-degree murder and 46 counts of felony assault.

Chambers' father says his daughter has been treated for mental illness in the past.

Chambers' attorney, Tony Coleman, said he has serious doubts about her mental competency and says she displayed characteristics of mental illness.

In November, Coleman submitted a competency report of his own.

According to court documents filed by Tony Coleman, a forensic psychologist found Chambers "incompetent to undergo further proceedings" and determined that she was "acutely psychotic and in need of immediate psychiatric treatment."

Prosecutors asked for a competency hearing, even though they believe Chambers was fully competent at the time of the crash.

She was moved to a psychiatric hospital where she underwent treatment so doctors could decide if she's mentally competent to stand trial.

Experts initially found Chambers showed "severe signs of mental illness," a much different opinion from the state's psychologist.

"We anticipated that, that’s quite common for that to occur," Chambers' attorney, Tony Coleman, said.
Coleman says the reason for the different test results has a lot to do with the timing. He thinks the first doctor's exam was done too soon after the crash. 
But doctors in Vinita say Chambers understands the charges against her and is capable of helping her attorneys with her case, and a Payne County judge announced that Chambers has been found competent to stand trial.
As for prosecutors, they still have a lot of evidence to sort through and witnesses to speak with. 
Coleman says he hasn't received any discovery yet from the state. 
"I'm sure law enforcement is still doing quite a bit of work on this and once they turn it over to them pursuant to the rules, they’ll turn it over to us," Coleman said.
So what legal strategy will Chambers' attorneys pursue? We asked Coleman if he'll prepare an insanity defense.
"I'm not going to disclose that just yet, we’re just letting things develop as they’re going, wait till we get all the discovery in our hands and then we’ll go from there," Coleman said.

The judge granted Coleman's request to reserve the right to bring up the competency issue at a later time.

A preliminary hearing is set for April 7th and a preliminary hearing conference is set for February.

She's being held on a $1 million bond.
