The woman charged with killing four people after she crashed her car into a crowd of people at a parade last year is seeking an insanity defense.
Adacia Chambers is charged with dozens of counts of felony assault and four counts of second-degree murder.
Police say she intentionally drove around a barricade before hitting people at Oklahoma State University's Homecoming Parade. More than 40-people were injured.
In December a judge found Chambers competent to stand trial. Her trial is scheduled to start next year.
