Mercedes Schneider dug into the background of Chris Clemons, the Atlanta charter school principal, who has been accused of stealing $600,000 from his school.

She found an article from his days at MIT, explaining how he developed a passion for teaching “impoverished children in urban areas.”

He trained as a school leader at “Building Excellent Schools,” a Boston-based program to prepare principals to open and run charter schools. He launched a charter school in Denver, his hometown. And then he went to Atlanta to open charter schools. He was charged by the FBI with theft, not only for the missing $600,000 from his current school, but for another $350,000 that was missing from two other charter schools that he ran.
