Several top officials and officers resigned after the election of the first-ever black mayor of a sleepy town in Missouri. Tyus Byrd was officially sworn in as mayor of Parma, Missouri, one week ago and thought she had a good relationship with the six municipal employees who stepped down with no warning. "I've never come across any racial problem here in Parma," Byrd told NBC News. "I've never encountered (it) here in Parma with myself of any other city official." Six of the 11 municipal employees who decided to quit include the Parma police chief, city clerk and the water department supervisor. None offered letters of resignation, Byrd said.
