A previously convicted sex offender, Michael Pinkerton, was sentenced on Mar. 13 to more than eleven years in prison for possessing child sexual abuse material while on supervised release for similar offenses.
Pinkerton, 48, of Topeka, pleaded guilty to one count of sexual exploitation of a minor involving the possession of child pornography. The case highlights ongoing efforts by law enforcement and the justice system to monitor individuals convicted of sex crimes and protect communities from further harm.
Court documents show that Pinkerton had previously been sentenced in September 2010 by a U.S. District Court judge in the Western District of Missouri to ten years in prison and five years of supervised release following convictions for attempted receipt and attempted possession of child pornography. In April 2024, while living in Kansas under supervision, two officers from the U.S. Probation Office visited his home and observed him attempting to hide an item. When questioned, Pinkerton admitted it was an unauthorized smartphone containing images of child sexual abuse material. Investigators later confirmed the presence of such material on the device.
“After child sex offenders complete their prison sentences, tools like supervised release and registries are used to monitor them and try to keep our communities safe from deviant behavior. These mechanisms worked in this case thanks to the proactive work of our probation officers,” said U.S. Attorney Ryan A. Kriegshauser.
The investigation involved the Federal Bureau of Investigation (FBI), the U.S. Probation Office, and Topeka Police Department. Assistant U.S. Attorney Sara Walton prosecuted the case.
This prosecution is part of Project Safe Childhood, a nationwide initiative launched by the Department of Justice in May 2006 aimed at combating child sexual exploitation and abuse through coordinated federal, state, and local resources.
