Joao Pierini (aka Joao Marcos) is the convicted felon, child molester, registered sex offender who was recently promoted to sixth degree BJJ blackbelt under Joe Moreira-- as I posted here.
First the good news-- I'm told that the academy heads in the area around Cancun where Pierini teaches have banded together, informed local schools, and gotten law enforcement authorities involved.
But the bad news-- Pierini was invited to teach a seminar at the Brasa affiliate in Cancun where the instructor is Ismael Sacramento. I've messaged Prof. Felipe Costa to get his input on this.
Also bad news, Pierini is apparently teaching at the Lotus affiliate in Playa del Carmen. I've messaged Prof. Giva Santana inquiring, as well. In a brief reply (since he's at Nationals in Vegas) Prof. Santana assures me that the Lotus people there are not affiliated with *his* Lotus. He'll explain more when he returns from competing and I'll update you then.
I hear that Pierini is lying and telling people that he was merely fined for buying alcohol for minors. Folks, if you have any access to students or families in Quintana Roo, Mexico and that general area, please encourage them to look at the screen shots in this blog. It's way worse than getting teens some booze. He's a predator.
