A 36-year-old homeless man is being held in the Pike County Jail after investigators say he sexually assaulted a child under the age of 13, capping a multi-agency probe that stretched across several west-central Illinois counties. Jack L. Green was arrested in Mount Vernon, Illinois, on August 18 and now faces two counts of predatory criminal sexual assault of a child under 13, a Class X felony under Illinois law.
According to whig.com, the Pike County Sheriff's Department received a report on August 5 alleging a sexual offense against a juvenile victim under 13. Chief Deputy Zachary Orr, who was assigned to the case, identified Green as a suspect and then spent the following two weeks conducting interviews and collecting evidence, the outlet reports. An arrest warrant was issued August 18, and Green was taken into custody in Mount Vernon just hours later.
Green appeared in Pike County Circuit Court the following day, August 19, where Judge J. Frank McCartney ordered him detained pending further proceedings, per the same account. McCartney serves as Chief Judge of Illinois's Eighth Judicial Circuit, which covers eight western Illinois counties including Pike, Adams, Brown, Calhoun, Cass, Mason, Menard, and Schuyler, according to Illinois Courts. Pike County itself is a rural county of 14,739 residents bounded by the Mississippi and Illinois rivers, with Pittsfield as its county seat, per Ballotpedia.
A Web of Agencies Across County Lines
The investigation drew in an unusually wide roster of law enforcement and child-protection agencies. Per the sheriff's department, assistance came from the White Hall Police Department, the Mount Vernon Police Department, the Roodhouse Police Department, the Carrollton Police Department, the Greene County Sheriff's Office, and the Pike County State's Attorney's Office. Two specialized child advocacy organizations also joined the effort: the Pike County Child Advocacy Center and the Unified Child Advocacy Network, headquartered in Jerseyville.
The Pike County Child Advocacy Center operates as part of the regional Advocacy Network for Children, providing forensic interview facilities for abuse investigations across Pike, Morgan, and Scott counties, according to the Advocacy Network for Children. The Unified Child Advocacy Network, founded in 2017, coordinates multidisciplinary child abuse investigations and forensic victim interviews across five west-central Illinois counties, including Greene County, as reported by The Journal-News.
Orr, the chief deputy, said the case reflects the seriousness of crimes against children and the value of cooperation across jurisdictions. “Jurisdictional boundaries should never stand in the way of professionals working together,” Orr said, adding that he has dedicated his career to investigating crimes against children and advocating for victims, the outlet's report notes.
Prior Charges and Pending Release Status
Green was already navigating the criminal justice system before this arrest. The sheriff's department reported that he faced unrelated charges of unlawful use of a debit or credit card and unlawful possession of methamphetamine, and he was on pretrial release in Greene County on those unrelated charges at the time of his August arrest. Green's history in the region stretches back at least to February 2023, when he was arrested by the Carrollton Police Department, then listed as a 33-year-old Carrollton resident, on charges of possession of drug paraphernalia and an outstanding failure-to-appear warrant in Greene County, according to RiverBender.com.
Under Illinois's Pretrial Fairness Act, part of the broader SAFE-T Act, cash bail has been eliminated statewide, but prosecutors can petition courts to detain defendants without bond when they face non-probationable Class X forcible felonies and pose a specific threat to public or victim safety, according to state law. Because Green was already on pretrial release for a pending felony in Greene County when the new allegations surfaced, Illinois statute also allows prosecutors there to petition to revoke that release entirely, a step that would trigger a revocation hearing within 72 hours. It remains an open question whether Greene County prosecutors will pursue that revocation.
What Conviction Would Mean Under Illinois Law
Predatory criminal sexual assault of a child under 13 carries a mandatory statutory prison term of 6 to 60 years under Illinois law. Truth-in-sentencing guidelines in the state also bar day-for-day credit for this offense, meaning a person convicted must serve at least 85 percent of whatever sentence a court imposes. Anyone convicted would additionally face mandatory lifetime sex offender registration as a designated sexual predator upon release from prison, under the state's Sex Offender Registration Act.
Green remains in the Pike County Jail, and his preliminary hearing is scheduled for September 1 at 1 p.m. Whether additional charges or victims emerge as the multi-agency evidence collection continues is not yet known. As with all defendants, Green is presumed innocent unless and until proven guilty in a court of law.
