A registered sex offender has been charged with producing child pornography while he was committed to a sexual predator unit at Larned State Hospital, U.S.

Attorney Barry Grissom said today.

Christopher M. Case, 33, has been charged with two counts of producing child pornography and two counts of sending obscene material to a child. The indictment makes the following allegations:

– From Dec. 1, 2011, to Dec. 28, 2011, Case enticed a 15-year-old child to engage in a sexual act for the purpose of making a video to be transmitted on the Internet.
– From Dec. 24, 2011, to Jan. 23, 2012, Case enticed a 13-year-old child to engage in a sexual act for the purpose of making a video to be transmitted on the Internet.
– On Dec. 29, 2011, Case sent a video of himself masturbating to the 13-year-old victim
– On Dec. 31, 2011, Case sent a video of himself masturbating to the 13-year-old victim.

At the time of the crimes, Case was a registered sex offender. He was convicted in Saline County, Kan., in May 2003 on a charge of attempted aggravated indecent solicitation of a child.

If convicted on the federal charges, he faces a penalty of not less than 25 years in federal prison and a fine up to $250,000 on each of the charges of producing child pornography; and a penalty of not less than 10 years and a fine up to $250,000 on each of the charges of sending obscene material to a child. The Wichita Police Department’s Internet Crimes Against Children Task Force and the Kansas Attorney General’s office investigated. Assistant U.S. Attorney Jason Hart and Steve Karrer of the Kansas Attorney General’s Office are prosecuting.
