A 21-year-old St. Charles man who worked for a home cleaning company was sentenced to 14 years in federal prison this week after investigators found videos and photographs containing child sexual abuse material on his phone, along with a photograph showing him kissing a 4-year-old girl on the lips whom he encountered inside a client's home. Joshua J. Klenke pleaded guilty in June to one count of receiving child pornography, a case that began when he uploaded the material to Snapchat.
According to KTTN, the FBI and the St. Charles County Police Department investigated the case after the National Center for Missing & Exploited Children provided CyberTips concerning the material Klenke had uploaded. Court docket records reviewed for this story show Klenke was sentenced in Courtroom 14S of the Thomas F. Eagleton U.S. Courthouse in St. Louis before District Judge Zachary M. Bluestone under federal case number 4:25-cr-00524, according to the U.S. District Court for the Eastern District of Missouri. Klenke was formally indicted in October 2025 before entering his guilty plea in June 2026.
Assistant U.S. Attorney Jillian Anderson prosecuted the case, per the station's report. Anderson regularly serves as the primary prosecutor for federal child exploitation and Project Safe Childhood cases across the Eastern District of Missouri, according to the U.S. Department of Justice. Klenke must also serve 20 years of supervised release once his prison term ends, per the same account.
A Sentence Far Above the Federal Minimum
Under 18 U.S.C. § 2252A(b)(1), receiving child pornography carries a mandatory minimum of five years in federal prison and a maximum of up to 20 years, per the Department of Justice. Klenke's 168-month sentence lands well past that floor. U.S. Sentencing Commission data cited by the Federal Public Defender for the District of Kansas shows federal defendants convicted of receiving child pornography serve an average of 95 months, or nearly eight years, meaning Klenke's penalty is nearly double the national baseline. Aggravating factors, such as evidence of physical contact or abuse photos, often push sentences far above base guidelines, according to the same source.
Notably, on the same day Klenke was sentenced, federal prosecutors in the Eastern District of Missouri secured a 40-year prison sentence against a Southeast Missouri man convicted under Project Safe Childhood, according to the Department of Justice. Federal judges in the district frequently hand down double-digit prison sentences for child exploitation offenses, the agency notes.
How the Case Was Built
The investigation traces back to an automated system that flags exploitative material at massive scale. Snap Inc. submitted approximately 752,000 CyberTip reports regarding potential child exploitation to NCMEC in 2025, and over 200,000 more in early 2026 following platform safety updates, according to the U.S. Senate Committee on the Judiciary. Snapchat is among eight major tech platforms that generate the vast majority of federal child exploitation tips nationwide, the committee found.
NCMEC's CyberTipline received more than 61.8 million total file reports of suspected child sexual abuse material in 2025 alone, according to the National Center for Missing & Exploited Children, which serves as the national clearinghouse that routes digital leads to local ICAC task forces. Locally, the St. Charles County Police Department has managed the Missouri Internet Crimes Against Children Task Force since 2011, coordinating digital forensics and exploitation probes across more than 80 affiliate agencies statewide, according to the Missouri ICAC Task Force. That unit operates out of O'Fallon with investigators and forensic examiners across eastern Missouri.
Statewide Resources Behind Local Cases
The Missouri State Highway Patrol also established a dedicated Special Victims Unit in 2024 that combines digital forensics and human trafficking capabilities to support regional ICAC task forces and NCMEC probes, according to the Missouri State Highway Patrol. The unit provides specialized mobile device analysis and online undercover capabilities, the agency says.
Klenke's case is prosecuted under Project Safe Childhood, a Department of Justice initiative launched in May 2006 to unite federal, state, and local law enforcement against online child exploitation. The program is co-led by U.S. Attorneys' Offices and the department's Child Exploitation and Obscenity Section, per the Department of Justice.
Part of a Pattern in St. Charles County
Klenke's case is the latest in a string of child exploitation prosecutions tied to St. Charles County in recent months. Hoodline previously reported that a St. Charles assistant principal was barred from campus amid a child pornography investigation, and a Wentzville firefighter was sentenced to 22 years and called a danger to the community after CyberTips from NCMEC led investigators to him. A St. Charles couple also faced a slew of child exploitation charges earlier this year, and last year an O'Fallon man was sentenced to 78 months on similar federal charges.
