A man was sentenced to prison for child pornography charges, and investigators said he met his victim on a cell phone game.

Stephen A. Turner, 36, was sentenced to 27 years in federal prison production of child pornography and 15 years of supervised release after release.

According to a press release from United States Attorney Donald S. Boyce, Turner used the chat function of "Marvel: Contest of Champions" to meet an 11-year-old girl. He then texted with her to build a relationship before asking her to send him a photo of her genitals.

The girl's mother discovered the messages and reported the crime to police.

The investigation was carried out by the Wood River Police Department and a sheriff's department in Florida. The case was prosecuted by Assistant United States Attorney Laura V. Reppert in Southern Illinois.
