Washington ? Less than two minutes after Angie Wilson entered an online chat room posing as a 14-year-old girl, older men began sending her messages.

It didn’t take long for some messages to turn graphic, with one of the men sending Wilson, a special agent with the Kansas Bureau of Investigation, a sexually explicit image of himself.

Kansas Atty. Gen. Phill Kline asked Wilson to replay a recorded version of her Web chat Monday at a conference where state attorneys general from across the country discussed ways to combat the growing problem of predators soliciting sex from children over the Internet.

The sting is an example of the work at the Kansas City, Mo., Cybercrimes Task Force, which teams federal, state and local officials to track down child predators who use the Internet to lure children into real-life sexual encounters.

“We saw some of the grotesque visuals here, but let me tell you what is truly frightening,” Kline told a working group of the National Association of Attorneys General. “That is the sophisticated nature of these sexual predators and how organized they are.”

Kline singled out one Web site that he said explains the age of consent for sex in every state, describes the state-by-state penalties for sexual offenses and even provides links to attorneys who specialize in defending those caught soliciting sex from children.

Articles on the site also discuss how to target children who seem to be loners, frightened or looking for friends and explain how to establish a pen pal relationship, Kline said.

“This Web site is actually like a college for pedophiles on how to meet children on the Internet,” Kline said.

In the last six months, investigations by the Kansas City Cybercrimes Task Force — one of 19 in the United States — have resulted in 22 indictments, 20 arrests and 11 convictions for sex crimes against children, Kline said.
