Arthur Dixon, executive director, and James Hinton, housing coordinator for United Neighborhoods Inc. (UNI), were in charge of administering federal funds received from the Department of Housing and Urban Development (HUD) for the city of Peoria, Illinois. They had the authority to enter into contracts with suppliers and tradespeople to provide the necessary materials to rehabilitate houses in the city of Peoria. While contracting with the suppliers and tradespeople, they used their positions to extract a 10 percent payment back on all contracts they awarded. What crime have Dixon and Hinton committed?
