A woman accused of driving her car into Oklahoma State's homecoming parade, killing four people and injuring dozens, has pleaded not guilty to the charges against her.
Adacia Chambers entered her plea Wednesday in Payne County District Court after previously waiving her right to a preliminary hearing.
The 25-year-old Chambers is charged with four counts of second-degree murder and more than 40 counts of assault and battery in the Oct. 24 crash.
Prosecutors say Chambers intentionally drove her car around a barricade and into spectators at the parade. Her attorney, Tony Coleman, says his client is mentally ill.
A pretrial conference is set for June 1, but Judge Stephen Kistler did not set a trial date after Coleman said he is still seeking information from prosecutors.
