In 2006, Pierini assaulted teenage boys in Half Moon Bay CA and pled no contest ( to 1 felony, 3 misdemeanor charges of child molestation) and was convicted in 2007.
He was deported after a year in jail and is a lifetime registrant on the sex offender registry.
In 2010 he sneaked back into the United States illegally.
Mugshot from his original arrest for child molestation.
Detail from the probation violation case (sneaking back into the US) when it was on appeal. Contains detail from the original convictions. I don't have all the screen shots, sorry, just the ones most relevant to the facts of the cases.
June 30, here's Joao Marcos Pierini, posting as Joao Campeoes Marcos, in Mexico.... compare to the photos in this post. It's Pierini in the well-striped-up blackbelt. June 30 is the facebook post date... the actual promotion took place June 27, 2015 (look at the certificate below.)
And here's Joe Moreira promoting Pierini...
Read the certificate. And guess how old the young man he has his arm around is. (I do not know, but he's a green belt so I blanked out his face.)
I am grossed out.
Pierini aka Marcos is the Mestre at Live to Fight in Cancun, Playa del Carmen, Quintana Roo, Mexico.
