STILLWATER, Okla. - A driver charged in the OSU homecoming tragedy is competent to stand trial, a judge announced Thursday.
In all, authorities said four people were killed and 46 others were injured 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.
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.
