Emmanuel Mudiay was born in Kinshasha, in the Congo, where he lived until he was five. He lost his father and lived through a civil war that made bombings, gunfire, and ethnic violence an everyday reality. His family moved to Arlington, Texas, where Mudiay played high school ball at Prime Prep, a charter school founded by Deion Sanders which is now defunct and facing serious debts and lawsuits. After Prime Prep was exposed as a fraudulent institution, there were questions about Mudiay's transcripts at Southern Methodist University, where he was going to run the point for James Dolan's Public Enemy #1, Larry Brown.
