A 38-year-old Cheyenne man was sentenced to 15 years in federal prison on child pornography charges Monday, the U.S. Attorney's Office said.

Jeremy Lee Sestak pleaded guilty in July to possession and distribution of child pornography​.

In December 2018, Sestak came to the attention of the Wyoming Internet Crimes Against Children Task Force through the receipt of a Cybertip regarding the sharing of child pornography via Tumblr.

Subsequent investigation indicated Sestak took sexually explicit photographs of a 4-year-old child.

Sestak will be on supervised release for 10 years once he's released from prison.
