Lori Vallow Daybell has waived her right to a preliminary hearing, according to a document filed in Idaho's 7th Judicial District Court.
Vallow Daybell's waiver of a preliminary hearing requires her to appear in District Court and enter pleas for the charges against her. Her arraignment date has not yet been scheduled.
Both she and her husband, Chad Daybell, are charged with conspiracy to commit destruction, alteration or concealment of evidence in connection with the disappearance of Vallow Daybell's two children, Joshua "JJ" Vallow and Tylee Ryan.
The kids had been missing since September, until their remains were found buried in Chad Daybell's backyard on June 9.
Earlier this week, Magistrate Judge Faren Eddins ruled there is sufficient probable cause for Chad Daybell to go to trial in District Court for his charges.
Judge Eddins made the ruling after hearing two days of testimony from 12 witnesses, along with closing arguments from state prosecutor Rob Wood and Daybell's defense attorney John Prior.
