A federal prosecutor charged with traveling from Florida to Michigan to have sex with a 5-year-old girl committed suicide on Friday in prison, his lawyer said.
The prosecutor, J. D. Roy Atchison, 53, was arrested on Sept. 16 leaving a plane in Detroit as part of an Internet sting operation led by the sheriff's department in Macomb County, Mich.
The authorities said he had been chatting online for two weeks with an undercover detective who posed as a mother offering to let men have sex with her young daughter.
At the time of his arrest, the authorities said, Mr. Atchison, of Gulf Breeze, Fla., was carrying a Dora the Explorer doll, hoop earrings and petroleum jelly.
