A woman accused of purposely driving around a barricade and over a police motorcycle before crashing into spectators at Oklahoma State University's homecoming parade has been formally charged with four counts of second-degree murder and 46 counts of felony assault.
Payne County District Attorney Laura Thomas filed formal charges Wednesday against 25-year-old Adacia Chambers of Stillwater.
Chambers has remained jailed in Stillwater on $1 million bond since the Oct. 24 crash. A judge ordered a psychological evaluation.
In Oklahoma, second-degree murder charges are warranted when someone acts in a way that's "imminently dangerous to another person" but does so without premeditation.
Each count is punishable by at least 10 years in prison. A telephone message left Wednesday with Chambers' attorney, Tony Coleman, wasn't immediately returned.
