A woman charged with killing four people and injuring dozens of others after crashing her car into spectators at Oklahoma State University's homecoming parade has waived her right to a preliminary hearing.

That means 25-year-old Adacia Chambers will go on trial for second-degree murder charges and more than 40 counts of assault and battery in the Oct. 24 crash that prosecutors say was intentional.

A trial date has not been set.

Payne County court records show Chambers was advised of her rights Tuesday, then waived her right to a preliminary hearing, which determines whether there is sufficient evidence that a crime occurred and probable cause the defendant committed it.

Chambers' defense attorney Tony Coleman has said she is mentally ill. He didn't immediately return messages left seeking further comment.
