The federal prosecutor from Florida who was arrested in a child-sex sting in Michigan last month has killed himself in prison:

J.D. Roy Atchison, 53, of Gulf Breeze was found unresponsive in his cell Friday morning in the special housing unit of the Federal Correctional Institution in Milan, Mich…

“His death appears to be the result of suicide,” Truman said. “A thorough investigation is under way.”

…He was arrested Sept. 16 at the Detroit Metropolitan International Airport after corresponding over the Internet with a Macomb County (Mich.) Sheriff’s Office detective who posed as a mother interested in allowing men to engage in sex with her fictitious 5-year-old daughter, authorities said.
