A Phoenix woman accused of mailing a powdery substance to the Maricopa County Sheriff's downtown headquarters to get her ex-boyfriend in trouble has pleaded guilty in the case.

County Superior Court officials say 25-year-old Alma De Paz Pacheco pleaded guilty Friday to one count of solicitation to commit hoax.

She's scheduled to be sentenced on June 28.

The letter's discovery last August led the sheriff's office to evacuate a floor of its building.

Tests later showed the substance was cornstarch and not a poison or toxic material.

Detectives investigating the case located a man listed on the envelope's return address.

He told them his former girlfriend Pacheco threatened to get him in trouble by mailing cornstarch to police.

Sheriff's deputies say Pacheco admitted sending the letter and she was arrested.
