John David Roy Atchison (August 28, 1954 – October 5, 2007) was an American assistant U.S. Attorney in Florida's northern district who was arrested on suspicion of soliciting sex with a 5-year-old girl. He was also a volunteer coach for girls' softball and basketball teams, and president of a youth sports association. He was arrested in a sex crime sting operation, and charged with "enticement of a minor to engage in sexual activity using the Internet", "aggravated sexual abuse," and "traveling across state lines to have sex with someone under the age of 12". Atchison committed suicide by hanging himself in his prison cell in Milan, Michigan, three weeks later.
