Jefferson County, Illinois — Three men were arrested following a child pornography investigation that began with a tip received by the Jefferson County Sheriff’s Office.
According to the Jefferson County Sheriff’s Office, detectives received information on Jan. 8, 2026, about the possible production of child pornography. Investigators began reviewing the information and made contact with Marcus W. Leyva, 37, of Woodlawn, at his residence the same day.
Authorities said the contact resulted in Leyva’s arrest and the seizure of evidence for further investigation. He was taken to the Jefferson County Jail and detained pending trial.
Investigators said evidence collected from Leyva’s residence allegedly led detectives to identify additional suspects who may have been involved in child pornography offenses. Search warrants were obtained to review electronic records from multiple sources.
Following that review, Cody J. Shepler, 25, of Mt. Vernon, was arrested on March 10, 2026.
Leo R. Barnett III, 29, also of Mt. Vernon, was arrested on March 13, 2026, according to the sheriff’s office.
Prosecutors charged Leyva with two counts of Class X felony dissemination of child pornography and five counts of Class 2 felony possession of child pornography.
Shepler was charged with five counts of Class 2 felony possession of child pornography, while Barnett faces five counts of Class 2 felony possession of child pornography, authorities said.
All three men were booked into the Jefferson County Jail and are being held pending court proceedings.
Cases involving online exploitation often prompt broader digital investigations, a growing focus for law enforcement as internet use expands among students, young workers, and households across the region.
