Ten people have been arrested in a child solicitation sting in Johnson County, called Operation: Firewall.

At a news conference Friday morning, Sheriff Duane Burgess said the people were arrested when they showed up at a house in Greenwood to have sex with someone they thought was an underage girl.

"These individuals represent ones who went beyond that conversation and physically showed up to the location," said the sheriff. "Detectives created a false profile of a young female on a sex-oriented website. During the chat it made clear that the female was underage."

Burgess said the conversation turned sexual and some people were turned off right away and left the chat.

"Some individuals decline immediately upon learning the age. Others just want to engage in some type of sexual fantasy."

Burgess said low-level solicitation arrests sometimes result just from continuing the chat. But, the people are hard to find, if they don't actually make arrangements and show up.  Burgess said the operation was a collaboration with the Johnson County prosecutor's office and that detectives put a lot of work and research into making strong cases.

"The sheriff's office follows many social media sites in the process and researching we find information that we see, people talking on the internet. We may hear talk of human trafficking or people being taken from a shopping center."

The charges resulting from this week's sting are child solicitation, two charges of providing pornographic pictures to a minor and one drug arrest.
