A Harrison County man was arrested on child pornography charges after a two-year investigation.

Allen L. Moredock, 26, was charged with 20 counts of possession of matter portraying a sexual performance by a minor, state police said Wednesday in a news release.

An Internet Crimes Against Children investigation started when Moredock began chatting with a person online who he thought was a 14-year-old girl, the news release said. The "girl" was an undercover detective in Florida.

The news release said Moredock sent the detective child pornography and talked about having sexual contact with a child.

Florida officers determined that the suspect was in Berry, Ky., and forwarded the case to Kentucky State Police.

Moredock was arrested Oct. 18, the news release said. Officers took multiple computers and found more than 1,000 images of child porn. He was being held at the Bourbon County Detention Center on $100,000 cash bond.
