Authorities have not yet located her body, but believe she is dead, and have charged Frazee with two counts of first-degree murder.
Frazee is charged with two counts because investigators have two theories about how he was connected to Berreth's death. Prosecutors contend that Frazee either ordered a robbery that resulted in Berreth's murder or premeditated and carried out the murder himself.
Affidavits connected to the case are sealed so it's unclear what evidence the prosecution has against Frazee. He is due back in court on Feb. 19.
