A 21-year-old O'Fallon man is being held at the St. Clair County Jail after Illinois Attorney General Kwame Raoul's office charged him with 10 counts of possessing child sexual abuse material, following a search of his home this week. Henry Alvarez-Mendez is scheduled for a detention hearing Friday, where prosecutors will argue he should remain in custody without bail.

According to RiverBender.com, investigators with Raoul's office searched Alvarez-Mendez's home in the 1200 block of Greenfield Place on Wednesday and found evidence of child sexual abuse material, leading to his arrest. Each of the 10 counts is a Class 2 felony, and under Illinois law, a conviction on even one count carries a potential sentence of three to seven years in prison, according to the Law Offices of Andrew M. Weisberg. A conviction would also trigger mandatory lifetime registration on the state sex offender registry, the firm notes.

Because Illinois eliminated cash bail statewide under the SAFE-T Act, prosecutors cannot simply set a bond to keep Alvarez-Mendez in custody. Instead, under the state's Pretrial Fairness Act, they must convince a St. Clair County judge by clear and convincing evidence that he poses a real and present threat to community safety before he can be detained without release, per the Illinois General Assembly's framework governing the law. Assistant Attorney General Ruben Herrera is prosecuting the case for Raoul's High Tech Crimes Bureau.

A Familiar Pattern in O'Fallon

The case is at least the third in recent years in which Raoul's office has charged an O'Fallon resident with child sexual abuse material possession following an Internet Crimes Against Children task force search. In May 2025, the office charged 55-year-old Jeffery Odegaard of O'Fallon with 15 Class 2 felony counts after a search on Main Street, and in April 2024, it charged 45-year-old Seth MacDonald of O'Fallon with 11 felony counts following a joint search of his home by local and university police, as Hoodline previously reported. A separate case surfaced two weeks ago when an O'Fallon man already on lifetime probation was charged after a Glen Carbon sex sting, according to Hoodline's coverage.

The charges reflect the state's use of updated legal terminology. Effective January 1, 2025, Illinois enacted Public Act 103-0825, amending state criminal statute 720 ILCS 5/11-20.1 to replace all legal references to child pornography with child sexual abuse material, reflecting that minors cannot consent to sexual exploitation, according to the Illinois General Assembly. As with all defendants, Alvarez-Mendez is presumed innocent until proven guilty in a court of law, and it will ultimately be up to the court to determine any sentence.

Task Force Cites Rising Volume of Reports

The Illinois Internet Crimes Against Children Task Force, which Raoul's office runs with a U.S. Department of Justice grant, is one of 61 such task forces nationwide and includes a network of more than 200 local, county, state, and federal law enforcement agencies. The task force received 45% more cybertip reports in 2025 than in 2024, the office said, tips that originate from the National Center for Missing and Exploited Children's CyberTipline and are forwarded to task forces like Illinois's for investigation.

That local surge tracks with a broader national trend. NCMEC's CyberTipline received 21.3 million reports containing 61.8 million files in 2025, and reports involving generative artificial intelligence CSAM or attempts to generate it topped 182,000 nationwide that year, following a 1,325% surge in AI-related reports during 2024, according to the National Center for Missing & Exploited Children. Online enticement reports rose 158% nationwide in 2025 to more than 1.4 million, up from 546,333 in 2024, a jump the organization attributes in part to mandatory reporting expanded under the federal REPORT Act. Financially motivated sextortion reports targeting minors also climbed, reaching over 50,000 in 2025, an average of 137 per day, up from more than 36,000 the year before.

Attorney General Points to Task Force Record

In a statement, Raoul said his office will continue partnering with state and local law enforcement to find and stop people who exploit minors, and that survivors of child exploitation and their families deserve justice. Since 2019, the Illinois ICAC Task Force has received more than 82,900 cybertips and been involved in more than 1,250 arrests of sexual predators; going back to 2006, that arrest total exceeds 2,600. The task force says it rescued more than 30 child victims from ongoing abuse in 2025 alone and has provided internet safety training and education to more than one million parents, teachers, and students, along with training for more than 25,000 law enforcement professionals.

Raoul also reminded the public that child abuse can be reported online through the Illinois DCFS reporting website, and that child sexual exploitation can be reported at CyberTipline.com. Local child advocacy centers are listed at childrensadvocacycentersofillinois.org. The pattern of ICAC prosecutions in the region has also included steeper penalties in more severe cases; in April, a Chicago man was sentenced to 24 years in prison after pleading guilty to four counts of disseminating child sexual abuse material, a charge that carries higher Class X felony exposure than possession, Hoodline reported at the time.
