Chris Cagle was charged with misdemeanor assault early Thursday morning (Dec. 13) following a benefit concert at the Cactus Moon Cafe, a nightclub in Tucson, Ariz. According to local police, Cagle, 39, was asked by an angry woman to keep signing autographs for her -- after he had already signed several items for her. When he declined, she began to call him names, and he allegedly punched her boyfriend in the face. The altercation was discovered by a police officer who drove past the club shortly after 1 a.m. Police said Cagle explained what had happened and cooperated with the investigation, but the woman's boyfriend decided to press charges. The concert, sponsored by Tucson radio station KIIM-FM, raised money for the Arizona's Children Association.
