A Missouri teen who pleaded guilty to killing her 9-year-old neighbor wants the pleas to be vacated, corrected or set aside.

Alyssa Bustamante pleaded guilty to second-degree murder and armed criminal action for the October 2009 killing of Elizabeth Olten in St. Martins, just west of Jefferson City. Bustamante was 15 at the time.

Bustamante's attorney contends the teen's due process rights were violated and that she faced cruel and unusual punishment. The lawyer also asserts Bustamante's public defenders were not effective. A hearing was scheduled Friday in Jefferson City.
