Using a hidden camera and the unpaid help of a mold remediation expert, reporters at KDFW exposed severe problems with the Wilmer-Hutchins district high school. News cameras also caught the district using illegal immigrants instead of mold remediation specialists to repair building problems. The investigation also lead to the discovery of mismanagement and fraud in the school district's leadership and its financial records. As a result of this report, a state education agency audit followed, along with investigations by the FBI, IRS, U.S. Department of Labor Wage and Hour division, and the Federal Bureau of Immigration and Customs Enforcement. Throughout the investigation, district officials denied any wrongdoing, refused to hand over documents, and were eventually charged with tampering with evidence in the federal investigations.
