When blogger Sarah Karp started digging through a pile of Chicago Public School papers in 2013, neither she nor anyone else could have imagined that her curiosity and sense of public service would lead to the downfall of the nation’s third largest school district’s top official.

Last Thursday, former Chicago Public School CEO Barbara Byrd-Bennett was indicted by a federal grand jury for funneling no-bid CPS contracts to former employers in exchange for kickbacks.

On Tuesday, Byrd-Bennett pleaded guilty and faces seven and a half years in federal prison, U.S. attorneys say.

Sarah Karp, whose son attends sixth grade at a Chicago public school, said while reviewing CPS paperwork, she found that the CPS Board had quietly approved a $20-million contract with SUPES Academy, a non-profit educational group where Byrd-Bennett had worked before taking charge of Chicago Public Schools.

That scenario didn’t set right with Karp. She wrote in July 2013 about her findings on Catalyst Chicago, a blog that covers urban school issues.
