An FBI analyst has been arrested following an undercover Internet sting and charged with distributing child pornography.
Keith Michael Dietterle, of the District, is accused of sending the images and videos to a man he befriended in an Internet chat room often used by people who have a sexual interest in children. However, Dietterle's new online friend was a D.C. police detective.
Dietterle, 28, who worked out of the FBI Headquarters in downtown D.C., was arrested last week by members of a joint FBI-D.C. police child exploitation task force.
Dietterle has since been dismissed as a result of the investigation, FBI spokesman Paul Bresson said Tuesday. Bresson would not give specifics about Dietterle's job or how long he'd been employed by the FBI.
He is being held without bond until his detention hearing, set for Dec. 20 in federal court in the District. If convicted, Dietterle faces a sentence of five to 20 years in prison. His attorney, Edward Sussman, had no comment Tuesday.
According to charging documents:
Dietterle believed he was communicating with a man who was having sex with a 3-year-old nephew and his own 12-year-old daughter.
"So hot man ... how'd it start?" Dietterle wrote.
Over a period of two weeks, Dietterle sent the detective three images through Yahoo instant messenger of children being sexually abused by adults. He later sent instant messages of multiple links, which contained images of child pornography, including a 13-minute video, and six other videos of young children being sexually abused.
Dietterle and the detective arranged early last month to meet for the purpose of Dietterle to have sex with the detective's purported 3-year-old nephew.
The FBI analyst, however, emailed the next day and apologized for backing out.
"I'm so sorry I couldn't make Friday happen ... [things] got crazy at work and I ended up workin[g] 13 hours," he wrote, according to the charging documents.
Investigators said they obtained a subpoena on the email account used by the sender, which traced back to Dietterle at his home address on the 700 block of Ninth Street SE in Washington.
