The driver of a car that plowed into a crowd at Oklahoma State University's Homecoming parade last month was charged Wednesday with four counts of second-degree murder.

Adacia Avery Chambers, 25, is accused of intentionally driving through police barricades and into a crowd of people at the corner of Main Street and Hall of Fame Avenue at 10:30 a.m. on Oct. 24. Three people were killed in the crash: Marvin Stone, a retired OSU professor; his wife, Bonnie Stone, an OSU employee; and Nikita Nakal, a University of Central Oklahoma graduate student who had attended the parade with friends. A 2-year-old boy, Nash Lucas, later died of injuries he had sustained in the crash.

All four counts of second-degree murder carry a possible prison sentence of 10 years to life.

Chambers also faces 46 counts of assault and battery by means or force likely to produce death. Those charges are associated with other victims injured in the crash. Each count carries a possible sentence of up to life in prison.
