Ten men are now facing charges after a three-day undercover sting in Fort Worth caught them allegedly attempting to solicit minors online — and investigators say they’re not done yet.
The operation, dubbed Operation Spring Cleaning, ran from April 1 through April 3, 2026, and was coordinated across a striking number of agencies, all working in tandem to root out adults using the internet to target children under 17. The arrests mark one of the more sweeping local child predator stings in recent North Texas memory — and with nine additional suspects still under investigation, the fallout is far from over.
Who Was Arrested
The ten men taken into custody span a wide range of ages and backgrounds, which investigators say is part of a troubling pattern. The arrested suspects are: Jose Montalvan, 41; Stephen Milliken, 30; Humberto Aldana Caballer, 23; James Klump, 61; Jordan Kammerer, 26; Joel Stroud, 33; Santiago Luque-Calix, 28; Jose Morales-Puentes, 25; Michael Schweitzer, 48; and William Johnson, 19. The youngest is barely an adult himself. The oldest is 61. That range — nearly four decades between them — says something about who, exactly, is showing up in these investigations.
A Multi-Agency Effort
This wasn’t a one-department operation. Far from it. The Fort Worth Police Department’s Internet Crimes Against Children Unit led the charge, but they were joined by the Tarrant County Sheriff’s Office, the Texas Department of Public Safety, Crowley Police Department, Carrollton Police Department, Homeland Security Investigations, the U.S. Secret Service, and the FBI. Eight agencies. Three days. Ten arrests. And counting.
Investigators used multiple online platforms to identify the suspects — a deliberate strategy, since predators rarely stick to one app or site. The breadth of the digital dragnet reflects how seriously law enforcement is treating the problem of online child exploitation, particularly in an era when kids are more connected — and more reachable — than ever before.
What Authorities Are Saying
Fort Worth police didn’t mince words in their public statement. Officials said, “This operation is a strong reminder that law enforcement is already working to find anyone using the internet to target children,” adding a direct message to parents: they should “always be involved in who your children might be communicating with online or through social media platforms.” The statement closed with a pledge — “Through continued collaborations, we remain committed to protecting our most vulnerable and holding offenders accountable.”
It’s the kind of language law enforcement issues regularly after stings like this. But the sheer number of agencies involved, combined with the active investigations still underway, suggests this one carries a bit more weight than the typical press release.
The Investigation Continues
Nine more suspects. That’s the number still being actively investigated in connection with Operation Spring Cleaning. Authorities haven’t released details on those individuals, which means additional arrests could come at any time. The operation’s name — Spring Cleaning — feels less like a PR flourish and more like a statement of intent.
Still, the hard truth is that for every sting like this one, the platforms keep humming, the direct messages keep flying, and the kids keep scrolling. Law enforcement can sweep. Parents can monitor. But the problem, as investigators themselves seem to acknowledge, doesn’t end with ten arrests or even nineteen.
The real kicker? The youngest person arrested in an operation designed to protect children from predators is 19 years old — barely out of adolescence himself. That detail alone should give everyone pause.
