How did Guerdwich Montimere the 22 year old Texas high school basketball star get caught for age faking?

The athlete who graduated from a high school in Florida as a former basketball star, went to Junior College in Illinois for a little bit, and moved to Western Texas to go back to high school at the age of 22, saying he was a Haitian with a Haiti birth certificate, saying he lost his home to a 2008 hurricane, his parents were dead, but he really told a hugh lie about himself. Once again how did he get caught for age faking?, Florida people noticed him in an AAU tournament as Guerdwich Montimere as Jerry Joseph?, or a cop asked for his idea and he failed to show the cop, how exactly did Guerdwich Montimere aka Jerry Joseph get caught for age faking?, Thank you so much! I would greatly appreciate some answers.
