For Immediate Release
U.S. Attorney's Office, District of Kansas

WICHITA, KAN. – A Kansas man has pleaded guilty to an Internet sex crime that took place while he was in the Kansas Sexual Predator Treatment Program at Larned State Hospital

Mark D. Brull, 38, Larned State Hospital, pleaded guilty to one count of transferring obscene material to a child. In his plea, he admitted that while he resided at Larned State Hospital he became friends with co-defendant Ryan J. Dancosse, a resident of Wichita. Brull provided Dancosse with the passwords to Brull’s social networking profiles including Facebook, Twitter, Flickr and Youtube, as well as his email account. With Brull’s knowledge and agreement, Dancosse found and copied images of pornography and then uploaded the images to Brull’s accounts for others to see and discuss.

In April 2011, Brull and Dancosse began communicating with a 14–year-old boy living in Massachusetts. In April and May 2011 Brull communicated with the boy via email and telephone. Brull guided the boy to his social networking profiles on the Internet, where he knew Dancosse had uploaded pornography. The boy was able to view the images on his computer and then discuss them with Brull. The images included depictions of nude males performing sexual acts.

Sentencing is set for Oct. 4. Both parties have agreed to recommend to the judge a sentence of 10 years in federal prison.

Co-defendant Ryan J. Dancosse, 40, Wichita, Kan., pleaded guilty to one count of receiving child pornography. He is set for sentencing Oct. 2.
