STILLWATER — Prosecutors Tuesday said they plan to file a dozen more counts against the woman accused of driving her car into a crowd at the 2015 Oklahoma State University homecoming parade.

Payne County District Attorney Laura Austin Thomas said in court Tuesday more victims of the Oct. 24 crash have been discovered.

Adacia Avery Chambers, 25, of Stillwater, currently is charged with four counts of second-degree murder and 46 counts of assault and battery by means or force likely to produce death. All counts carry possible sentences of up to life in prison.

Chambers appeared in court Tuesday in shackles and an orange jail uniform. She remained blank-faced, silent and calm. A few reporters took video and photographs of Chambers through windows on the courtroom doors. It was the first time she was able to be photographed by reporters since her arrest. The brief court appearance was to make sure attorneys were still on track for her April 7 preliminary hearing.
