Indiana’s Online Predator Hunt Is Growing and a Former FBI Analyst Is Among the Latest Accused

Five men drove more than 400 miles believing they would meet minors in Columbus, authorities say. One creeper and criminal arrested allegedly spent nearly three decades with the FBI. The arrests come as Indiana confronts tens of thousands of cyber tips and hundreds of suspected offenders each year.

Lawyers for years complained to the FBI about juvenile court problems, sealed adoptions and child trafficking and many think the problem goes to the top of the justice system here.

COLUMBUS, Ind. — Five men allegedly drove a combined distance of more than 400 miles to Columbus expecting sexual encounters with minors. Instead, authorities say, they encountered undercover investigators in one of Indiana’s latest multi-agency operations targeting suspected online child predators.

The arrests themselves are disturbing. But the larger numbers behind them may be even more troubling.

Indiana’s Internet Crimes Against Children Task Force received 29,635 cyber tips in 2025 — 38 percent more than in 2024 — and conducted 3,164 investigations that resulted in 499 arrests. Authorities say 126 children were rescued from ongoing abuse. By the first four months of 2026, the task force had already processed nearly 7,000 additional cyber tips, made 139 arrests, identified 171 child victims and rescued 15 children from active abuse.

Those figures put this week’s Bartholomew County sting into a much larger and increasingly uncomfortable context: online sexual exploitation of children is not an occasional Indiana crime story. It has become a continuing law-enforcement operation involving hundreds of officers, thousands of investigations and nearly 30,000 tips in a single year.

And one of the latest defendants reportedly comes from inside the very institution Americans associate with hunting such offenders.

Former FBI analyst among the accused

Matthew Bruce Ciske, 48, of Richmond, is charged in Bartholomew Circuit Court with child solicitation and attempted sexual misconduct with a minor, both Level 4 felonies. According to reporting based on the probable-cause affidavit, Ciske told investigators after his arrest that he had worked 29 years as an analyst for the FBI. He also reportedly said he was studying through the Quaker Church to become a chaplain. (bluewaterhealthyliving.com⁠)

Those facts make Ciske’s case particularly striking, but they do not prove the charges against him. Like every defendant discussed in this article who has not been convicted, Ciske is presumed innocent unless prosecutors prove guilt beyond a reasonable doubt.

According to the affidavit as reported by the Richmond Palladium-Item, Ciske allegedly drove about 90 miles from Richmond to Columbus after communicating online with someone who had represented himself as a 15-year-old boy. The person was actually a Bloomington police officer participating in the under cover operation.

The reported communications appear particularly relevant to prosecutors because Ciske allegedly discussed the supposed teenager’s age and the legal risk involved. According to the report, he was arrested after arriving in Columbus on Aug. 18. He initially reportedly told police he expected to meet a 23-year-old but later acknowledged that the person with whom he had been communicating had identified himself as 15. His initial hearing is scheduled for Sept. 11.

The other four arrested in the operation were identified as Andrew Rodger Donat, 59, of Indianapolis; David Todd Hahn, 48, of Mount Washington, Kentucky; Luis Ernesto Nunez Machuca, 37, of Streamwood, Illinois; and Nathan Todd Jones, 49, of Thorntown.

Ciske, Donat, Hahn and Nunez Machuca were reported as facing child-solicitation and attempted-sexual-misconduct allegations. Jones was charged with child solicitation along with alleged possession of methamphetamine, marijuana and drug paraphernalia.

They allegedly came from three states

The sting was conducted over several days and hosted by the Bartholomew County ICAC operation as part of Indiana’s broader Internet Crimes Against Children Task Force.

Undercover officers used multiple social-media platforms and communicated with people investigators say believed they were talking to children.

“These five individuals traveled well over 400 miles total, believing they were going to have sexual contact with minors in Columbus,” Bartholomew County Sheriff Chris Lane said in announcing the operation.

The geographical spread is significant. Suspects allegedly traveled from elsewhere in Indiana, Kentucky and Illinois to reach Columbus. The law-enforcement operation was equally wide-ranging.

Participating agencies reportedly included the Indiana State Police, Department of Homeland Security, Indiana Intelligence Fusion Center, Bartholomew County Prosecutor’s Office, Bartholomew County Sheriff’s Office, Columbus Police Department, Bloomington Police Department, Jeffersonville Police Department, Westfield Police Department and sheriff’s departments in Jennings, Howard and Clinton counties.

Bartholomew County Prosecutor Lindsey Holden said cooperation between agencies is increasingly necessary because technology has created new vulnerabilities for children.

Columbus Police Chief Steve Norman similarly described the operation as preventive policing — trying to identify an alleged offender before an actual child becomes the person waiting at the meeting place.

That distinction is central to the ICAC strategy.

Police are not simply waiting for a parent to report that a child has already been victimized. Investigators increasingly receive digital tips, trace accounts and devices, enter online spaces undercover and sometimes pose as minors to determine whether adults will attempt to arrange encounters.

Nearly 30,000 tips in one year

Indiana’s ICAC operation is overseen by the Indiana State Police and is part of a nationwide system created to combat technology-facilitated child exploitation. Indiana’s task force includes more than 50 participating local, state and federal law-enforcement agencies, according to ISP.

The growth of the workload has been remarkable.

In 2021, Indiana ICAC received more than 7,500 CyberTips from the National Center for Missing & Exploited Children. Four years later, the reported 2025 total had climbed to 29,635.

Not every tip establishes a crime, and tips should not be confused with arrests or convictions. Some reports may concern the same person or material, and investigators must determine jurisdiction, identify users and establish whether criminal conduct actually occurred.

But the increase creates an enormous investigative burden nonetheless.

Indiana responded by expanding the number of officers associated with the task force from approximately 470 to 520 between January 2025 and February 2026, according to figures released by Gov. Mike Braun’s administration.

But in a state without lawyers the stuff can go on without fear. We don’t have lawyers now because of who?

And Columbus is far from the only 2026 sting.

A three-day Shelby County operation in March involved more than 75 officers and agents representing 21 agencies and task forces and resulted in 11 arrests — described at the time as a record for that type of Indiana ICAC operation.

Cases have meanwhile continued across the state. Investigations based on cyber tips have produced arrests this year in communities including Bloomington, Elkhart, Greensburg, New Albany, Austin and Batesville.

But arrests are only half of the story

A dramatic sting produces photographs, handcuffs and headlines. The harder question is what happens afterward.

That requires separating arrests from convictions.

Indiana and federal courts have produced substantial prison sentences in child-exploitation cases when prosecutors establish their cases. The offenses vary greatly — solicitation, possession and distribution of child sexual-abuse material, coercion and enticement, production of abuse material and actual sexual abuse are not interchangeable crimes — but recent sentencing cases demonstrate the potential consequences.

In April, Bobby Cyprus Linhart of Greenfield was sentenced to 40 years in federal prison after pleading guilty to multiple offenses stemming from his targeting of children as young as 12 through Instagram, Snapchat, X and other online services. He was also ordered to pay $68,000 in restitution. (Department of Justice⁠)

In May, Christopher David Sheese of Bloomfield received 15 years and eight months after pleading guilty to distribution and possession of child sexual-abuse material. Investigators said the case began with an ICAC cyber tip concerning material uploaded through Kik. (Department of Justice⁠)

In December 2025, Bryan Lee Fish of Mitchell was sentenced to 50 years after pleading guilty to sexually exploiting children and possessing child sexual-abuse material. Authorities said an ICAC investigation began after NCMEC alerts concerning material shared through X. (Department of Justice⁠)

Northern Indiana has seen comparable sentences. A Whitley County man received 35 years in September 2025 for sexual exploitation involving a 14-year-old, while a Monticello man received 25 years after admitting production of child sexual-abuse material involving a six-year-old child. (Department of Justice⁠)

Those cases show that at least some ICAC investigations are not ending with arrest announcements. They are ending years later with guilty pleas, federal convictions and lengthy prison sentences.

Indiana has seen an FBI insider cross this line before

The allegation involving Ciske also has an eerie Indiana precedent.

More than a decade ago, Donald J. Sachtleben of Carmel, who had served 25 years with the FBI and worked as a bomb technician on major terrorism investigations, became the subject of a child-pornography investigation.

That case was not merely an allegation that faded away.

Investigators traced online child-sex-abuse material from another suspect to Sachtleben’s Carmel residence. Indiana State Police and FBI Cyber Crime Task Force officers executed a search warrant there in May 2012. The government reported finding approximately 30 images and video files containing child pornography during an initial examination of his computer. (FBI Archives⁠)

Sachtleben ultimately pleaded guilty to child-pornography offenses as well as a separate national-security case involving his unauthorized disclosure of classified information.

In November 2013, a federal judge sentenced him to 140 months — 11 years and eight months — in federal prison, including a consecutive 97-month term associated with the child-pornography crimes. (FBI Archives⁠)

Sachtleben’s former résumé made the episode extraordinary. He had worked on some of America’s most consequential bombing and terrorism investigations, including cases associated with the Oklahoma City bombing and Unabomber investigation. Yet investigators ultimately found themselves investigating a former colleague. (FBI Archives⁠)

That historical case and the present allegation against Ciske should not be conflated. Sachtleben was convicted and sentenced. Ciske has only been charged.

But the two cases underscore an uncomfortable point: occupation, credentials, religious activity, education, security clearances or a career inside law enforcement cannot substitute for evidence — nor should they shield anyone from investigation when evidence points the other way.

The technology keeps changing

The current cases also demonstrate why traditional warnings to children about strangers no longer adequately describe the danger.

Instagram. Snapchat. X. Kik. Telegram. Encrypted chats. Direct messages. Anonymous accounts. Tim Tibow has sought to build an army to combat the problem.

Recent Indiana federal prosecutions show offenders moving across mainstream social-media platforms, messaging applications and encrypted systems. Investigators, in turn, increasingly depend upon digital forensics, provider records, IP addresses and reports routed through NCMEC. (Department of Justice⁠)

The problem is therefore simultaneously local and global. A child can be sitting in an Indiana bedroom while someone across town, across the state or across the country makes contact through a device.

The Bartholomew County investigation demonstrates the reverse: people willing to move from online conversation to an alleged physical encounter may themselves cross county and state lines.

Police say these five men together traveled more than 400 miles.

They allegedly found officers waiting instead of children.

Indiana should now measure more than arrests

Indiana’s escalating investment in ICAC appears to be producing arrests and rescues. The state’s own 2025 figures — 499 arrests and 126 children rescued — are significant.

But Hoosiers should expect the next level of transparency.

How many of those 499 arrests resulted in formal charges? How many cases were dismissed? How many defendants pleaded guilty? How many were convicted at trial? What sentences were imposed? How many offenders were placed on the sex-offender registry? How many people arrested in previous stings offended again?

Those numbers would provide a fuller measure of whether Indiana’s increasingly expensive and sophisticated enforcement system is merely finding suspects or permanently disrupting networks of exploitation.

There is also a preventive question that no number of arrests can entirely answer: Why are nearly 30,000 cyber tips reaching Indiana investigators in a single year?

Law enforcement can build larger task forces. Prosecutors can seek lengthy sentences. Parents can use parental controls and monitor children’s online activities. Technology companies can report suspected abuse.

But the volume suggests Indiana is fighting something far larger than a handful of men arriving at a Columbus meeting place.

The five arrests in Bartholomew County are therefore not the end of this story. They are a snapshot of a statewide battle occurring every day on phones, computers and social-media accounts — usually outside public view.

And the allegation that one of the latest defendants spent 29 years working for the FBI makes one lesson especially difficult to ignore:

There is no profession, title or résumé that should place anyone beyond scrutiny when the safety of children is at stake.

The charges against Ciske, Donat, Hahn, Nunez Machuca and Jones are allegations. Each is presumed innocent unless and until proven guilty in court.
