Cell Phone Seized After Being Carried Into Secure DOE Area

KANSAS CITY, Mo. – A former Lenexa, Kansas, man was sentenced in federal court today after child pornography was found on the cell phone he carried into a secure area at the U.S. Department of Energy’s National Security Campus in Kansas City, Mo.

Shaun Walker, 41, currently a resident of Springfield, Mo., was sentenced by U.S. District Judge Stephen R. Bough to 18 years in federal prison without parole. The court also sentenced Walker to 15 years of supervised release following incarceration. Walker will be required to register as a sex offender upon his release from prison and will be subject to federal and state sex offender registration requirements, which may apply throughout his life.

On Oct. 11, 2023, Walker pleaded guilty to one count of attempting to distribute child pornography over the internet.

Walker was employed by Honeywell Federal Manufacturing and Technology, which is contracted by the Nuclear National Security Administration, at the time of the offense. Walker entered an inner secure area of the U.S. Department of Energy’s Kansas City National Security Campus with his personal cell phone on Nov. 29, 2021. Walker contacted Kansas City National Security Campus security to self-report the violation.

Walker gave his cell phone to security personnel, who reviewed the cell phone to determine if any classified material was present on the phone. During the review, a security officer observed numerous images and videos depicting child pornography. Walker’s phone was seized in order to conduct a forensic examination.

Investigators found an encrypted folder on Walker’s cell phone that contained 21 images and a video of a 5-year-old girl. Investigators found dozens of additional images and videos of child pornography on Walker’s cell phone. Investigators also found thousands of WhatsApp chats between Walker and females he contacted through a livestreaming pornography website. Walker requested photos and videos of nude underage females conducting sexual acts. As a result of his WhatsApp chats, Walker received and distributed images and videos of child pornography.

This case was prosecuted by Assistant U.S. Attorney Catherine A. Connelly. It was investigated by the Department of Energy, Office of Inspector General.
