Adacia Chambers has been formally charged with four counts of second-degree murder and 46 counts of felony assault in connection with the car crash at Oklahoma State University’s homecoming parade last month.

Each murder count against Chambers is punishable by at least 10 years and up to life in prison, the Associated Press reports. Chambers, 25, is accused of running a red light and intentionally driving around a police barricade before crashing into spectators.

A judge has ordered a psychological evaluation for Chambers, and Payne County District Attorney Laura Thomas has formally requested a competency evaluation.

During her booking, according to a cause affidavit sign by Stillwater Police officer Kurt Merrill, Chambers said she had a history of treatment for mental health issues and felt suicidal at the time of the crash.
