The police chief, the mayor and a councilman in this small town resigned Friday amid an uproar over nude photos of the chief's 300-pound, tattooed wife that she posted on a Web site. Dozens of residents of the town of 1,500 had demanded Police Chief Tod Ozmun resign, and the district attorney recommended an obscenity investigation, but the City Council decided last week that the pictures were protected by the First Amendment. On Friday, Ozmun, Mayor Dale Moore and Councilman Clifford Barnard said they were stepping down because they were fed up with the public attention and criticism of the chief. Another council member resigned earlier over the council's support of Ozmun. "This has turned into a media circus," Ozmun said. "A big, fat, fucking, rolls of fat-like media circus."
