A 27-year-old Filipino man from Baltimore has pleaded guilty in a shocking case of child exploitation and sex trafficking. Christopher Allan Tisoy, who was living in the US on an H-1B visa as a medical technologist at Sinai Hospital, has admitted to conspiring with Joshua DeWitte, a former music teacher at Buckingham Browne & Nichols School in Cambridge, Massachusetts.
DeWitte, 50, had allegedly uploaded child abuse material showing the exploitation of a young boy on his Snapchat account and offered to pay other users to obtain and produce child pornography. In conversations on Telegram, Tisoy was involved in discussions about producing videos depicting the sexual exploitation of minor boys in the Philippines.
The case took a dark turn when DeWitte allegedly paid Tisoy nearly $24,000 for each video he produced and sent. The scheme is believed to have been in place since at least December 2024.
Tisoy pleaded guilty to one count of sexual exploitation of children and one count of conspiracy to commit sex trafficking of children. His sentencing date has been set for May 6, 2026. DeWitte's next court date is scheduled for January 21, 2026.
DeWitte had a long history working in the Cambridge public schools system, with 13 years of experience. Tisoy was lawfully in the US on his H-1B visa and worked as a medical technologist at Sinai Hospital.
The case has been prosecuted as part of Project Safe Childhood, an initiative launched by the US Justice Department in 2006 to combat child exploitation and sex trafficking. The investigation involved both men being arrested and charged in May, with DeWitte being indicted in October. Both are currently in federal custody.

can you believe this guys was living among us for years without getting caught 
his case is a stark reminder that even the most seemingly normal people can have dark secrets lurking beneath the surface 
it's heartbreaking to think about the victims of child exploitation and sex trafficking who are still out there 
we need to keep raising awareness about this issue and supporting organizations that work tirelessly to combat it 
It's not just the fact that they were exploiting kids for money, but also the production of child abuse material. That's just horrific. 
It just goes to show how far-reaching and damaging child exploitation can be. We need to be vigilant and report any suspicious activity.
can you even believe that someone who was working as a music teacher got caught up in something like this 
it's not like he was just a random dude on the dark web, he was a trusted adult with kids around him 
and that h-1b visa just made it even more twisted like how easy is it to get into a country these days? 
anyway, glad they're taking action and all but ugh the thought of what those kids went through is just heartbreaking 
. I mean, can you believe a music teacher got caught up in something like this? It's just sickening 
. And the fact that he was working with someone who was supposed to be a victim of exploitation himself is just crazy 
. Tisoy's whole thing about producing videos for money is just low 
.
. It feels like they're getting a slap on the wrist compared to what they deserve. I guess that's what happens when you let these things slide for too long... *sigh*
.
what's going on here?! 
. And it's not just that, he was making videos of minors being exploited... like, what even is wrong with people?! 
. And the fact that he was paid money for making those videos is just gross 
. We need to make sure that people like them are held accountable and that our kids are protected from people who would do something so messed up 
.
. It's like he was living this whole other life, and it's just horrifying. And the fact that both men are now in federal custody is some small comfort, I guess 
.
. It's just not right that these predators get to exploit and harm innocent children for their own twisted desires 
.
. I mean, come on, guys, what's next? Selling your soul for a decent Wi-Fi signal? 
The H-1B visa is meant for good people, not pedophiles in disguise. It's just sad that Tisoy and DeWitte thought they could get away with this for so long 
. On the bright side, Project Safe Childhood is still kicking, and people like them are making it harder for predators like these two to hide in plain sight 
.
.
.
.
. The fact that someone in a position of trust, like DeWitte with 13 years of experience working in public schools, was capable of such heinous crimes is just unbelievable 
. May justice be served on May 6, 2026 
As a society, we need to be vigilant and look out for each other, especially when it comes to vulnerable populations like children.
it's just crazy how people can use platforms like Snapchat and Telegram for bad stuff
