A motion hearing is scheduled for Tuesday morning in the Alyssa Bustamante murder case.
And the victim's mother has told reporters the hearing will involve a plea agreement in the case.
In November 2009, after a juvenile court certification hearing determined Bustamante could be tried as an adult, Cole County grand jurors charged the teen - then 15 1/2 - with first-degree murder and armed criminal action for killing Elizabeth Olten, 9, on Oct. 21, 2009, by strangling her, cutting her throat and stabbing her.
In a Facebook message Monday evening, Olten's mother, Patty Preiss, said Tuesday's plea hearing was being held "against my wishes."
Two county officials confirmed Monday night that a hearing had been scheduled, although it was not listed in the Missouri courts' statewide, online "Case.net" system.
Neither official would say what the hearing was about.
Messages sent to Cole County Prosecutor Mark Richardson and Public Defenders Donald Catlett and Charles Moreland were not answered Monday night.
