TULSA, Okla. — Prosecutors could call more than 200 witnesses for the trial of a woman accused of killing four people and injuring dozens by plowing her car into a crowd at Oklahoma State University’s homecoming parade last fall.

Victims, first responders, detectives and numerous spectators are on a list of 207 potential witness names filed this week in Payne County District Court in the case against Adacia Chambers.

Chambers has pleaded not guilty to four counts of second-degree murder and 42 counts of assault and battery in the Oct. 24 crash. Her attorneys have indicated they plan to seek an insanity defense.

Chambers’ attorneys filed a list of around 30 witnesses they plan to call to the trial starting Jan. 10, including co-workers at the burger and malt shop where Chambers worked, jailers, family members and mental health experts.

One person named on the prosecutor’s list walked up to Chambers’ car after it had crashed through a barricade and smashed into spectators. According to court documents, the witness went to the side door where Chambers was to ask what happened. The witness said “she had a gentle smile and said she was trying to kill herself,” and that “she wanted to be free,” according to the documents.

Another potential prosecution witness was Chambers’ manager at a burger shop located near the parade route. The boss reported that on the day of the crash, Chambers sat in a booth staring out the window “with a smirk on her face.” Chambers gave her boss two-week’s notice, saying she missed her family, the court documents stated.

Several of Chambers’ relatives are listed as potential witnesses for the defense. Attorney Tony Coleman will ask them to outline the professional help they sought for Chambers before the crash.

Coleman didn’t respond to repeated messages Friday seeking comment.

It’s impossible to know how many of the potential witnesses the state will call to trial, Payne County District Attorney Laura Austin Thomas said in a statement Friday.

The crash killed: 2-year-old Nash Lucas; Nikita Nakal, a 23-year-old MBA student from India at the University of Central Oklahoma in Edmond; and a married couple, Bonnie Jean Stone and Marvin Lyle Stone, both 65, of Stillwater.
