A Fort Drum man has been sentenced to more than 11 years in federal prison for trying to entice a 13-year-old female into sexual activity and possessing child pornography.

Richard L. Coleman, 23, who is originally from Georgia, was sentenced Monday in U.S. District Court to 136 months imprisonment for Oct. 26 guilty pleas to charges that he tried to lure the girl into a relationship via computer and had sexual images of children on his computer.

According to court documents, Mr. Coleman began corresponding with a 13-year-old girl on her MySpace page. The girl’s mother discovered the page and, as she was viewing it, was contacted by Mr. Coleman.

The mother then posed as her daughter, who had represented to Mr. Coleman she was 20. When the mother corrected him, saying she was 13, he stated that “”it was okay, he likes younger girls,”” according to a criminal complaint filed with the court.

Mr. Coleman then asked the mother to meet him the following weekend and allegedly sent her an image of an adult penis, which he said was his. He then told the mother he is a soldier and asked her to meet him “”at the mall.””

The investigation was turned over to Fort Drum’s criminal investigation division, with an agent logging onto the girl’s MySpace account. The agent and Mr. Coleman subsequently exchanged multiple messages, including others allegedly asking to meet and describing sexual activity that would occur.

In September, a meeting was arranged at a room on Fort Drum. Once outside the room, Mr. Coleman allegedly sent a text message to the girl’s cellular phone to say that he was there. The agent then came out of the room and took Mr. Coleman to the investigation division’s office for questioning.

He later admitted the crime to investigators, according to court documents, and child pornography was found on his computer.

In addition to the prison sentence, he must also undergo 25 years of supervision upon his release.
