ROANOKE, Va. — Vinton Voice – A Roanoke man has been sentenced to federal prison after sending child sexual exploitation material to an undercover FBI officer, a case that federal authorities say highlights the very real and ongoing threat posed by online predators.
Christopher Allan Johnson, 55, was sentenced to 40 months in federal prison after pleading guilty in December 2025 to one count of possessing child sexual exploitation material involving a prepubescent minor.
According to the U.S. Attorney’s Office for the Western District of Virginia, Johnson logged into the Kik social media app on October 10, 2024, after leaving the Veterans Affairs Medical Center in Salem. He joined a public group dedicated to incest, where he began communicating with an undercover FBI task force officer.
During the conversation, Johnson reportedly discussed fantasies involving children.
Investigators say the following day, without being prompted, Johnson sent the undercover officer three videos depicting children being graphically sexually exploited, including at least one involving a prepubescent minor.
Acting United States Attorney Robert N. Tracci called the case part of a broader enforcement effort against online predators.
“The threat from online predators is real and remains a key enforcement priority,” Tracci said. “We are thankful to the FBI for their diligent work in this case to identify a real threat and bring justice to help protect our children.”
FBI Richmond Division Special Agent in Charge Ian Kaufmann added:
“Today’s sentencing takes one more criminal offline, but we know this epidemic of child exploitation is far from over.”
The Bigger Picture in the Roanoke Region
Cases like this aren’t isolated.
According to the Virginia Sex Offender and Crimes Against Minors Registry:
- Roanoke City has approximately 100+ registered sex offenders
- Roanoke County has roughly 150+ registered offenders
- Across the broader Roanoke Valley region, the total number exceeds 300 registered individuals
(Exact numbers fluctuate as offenders move, register, or are removed.)
These are only the offenders who have been caught, convicted, and required to register.
Federal data shows:
- The National Center for Missing & Exploited Children receives tens of millions of cyber tip reports annually
- Online child exploitation cases have surged nationwide over the last decade
- Social media platforms and messaging apps are increasingly used in exploitation cases

A Community Responsibility
Child predators don’t wear labels. Many operate quietly online, hiding behind screens and encrypted apps. That’s why federal and state agencies continue to prioritize cyber investigations.
If you suspect online exploitation or inappropriate behavior involving minors:
- Report it to local law enforcement
- Submit tips to the FBI
- Use the National Center for Missing & Exploited Children CyberTipline
Protecting children is not political. It’s not controversial. It’s common sense.
When predators are caught, prosecuted, and sentenced, it sends a message — but the work is far from finished.
