A 56-year old man from Kansas City, MO was recently sentenced in federal court for attempting to distribute child pornography over the internet.

The U.S. Attorney's Office says 56-year old Donnie Brett Butcher was sentenced on March 15, to ten years in federal prison without parole. The court also sentenced Butcher to 10 years of supervised release following incarceration.

Butcher reportedly pleaded guilty on Aug. 17, 2018. Authorities says the investigation began when a federal undercover agent was contacted online by Butcher, who shared the password to two online folders that contained images and videos of child pornography.

FBI agents executed a search warrant at Butcher’s residence on March 6, 2017, and reportedly seized various electronics media, including a MacBook computer and an external hard drive.

Although Butcher admitted to agents that he downloaded and exchanged child pornography with his MacBook computer, which contained full-disk encryption, authorities say he refused to provide a password so that investigators could examine the computer.

Investigators, however, did find approximately 11,000 images and videos of child pornography on external storage devices, which reportedly included videos depicting bondage, bestiality and sexually explicit activity with toddlers.
