A former Georgia poll worker who sent a written bomb threat to an election superintendent under the guise of a voter was convicted Friday, officials said.

Georgia poll worker expected to be sentenced in May after pleading guilty to charges involving a bomb threat he made to a local elections office.

A former poll worker admitted to sending a false bomb threat to a Jones County polling location in federal court Friday morning. Nicholas Wimbish, 25, of Milledgeville, pleaded guilty to false information and hoax charges after falsely claiming in a letter to the Jones County elections superintendent that there was a “boom toy” at an early voting location in Jones County.
