In their suit, Madison and Mertens allege that the sheriff and his wife falsely stated that Madison and her husband practiced law without a license and lied to the police.

The suit is seeking an unspecified amount of damages, a retraction of what it terms false and defamatory statements, and a prohibition of future defamation.
