A Kansas man has been charged with sex crimes that allegedly occurred while he was being held in the Kansas Sexual Predator Treatment Program at Larned State Hospital, U.S. Attorney Barry Grissom said today.

Mark D. Brull, 38, Larned State Hospital, Larned, Kan., is charged with one count of attempting to entice a 14-year-old child to engage in sexually explicit conduct for the purpose of producing child pornography and one count of receiving and distributing child pornography. Co-defendant Ryan J. Dancosse, 39, Wichita, Kan., is charged with one count of receiving and distributing child pornography. The crimes are alleged to have occurred in April and May 2011.

The indictment alleges that while Brull was in the state hospital he communicated with the child and received child pornography via computer over the Internet.

Brull was adjudicated under the Kansas Sexually Violent Predator Act and involuntarily committed to Larned State Hospital in 1999.

The Kansas Internet Crimes Against Children Task Force, the Wichita Police Department and the Sudbury, Mass., Police Department investigated. Assistant U.S. Attorney Jason Hart is prosecuting.
