A former finance director for the San Diego Regional Economic Development Corporation who federal prosecutors say stole more than $400,000 from the nonprofit was sentenced Thursday to one year and a day in prison. Katherine Lu Acquista previously served as the EDC’s director of operations and accounting and used her access to the EDC’s bank accounts, credit cards, checkbook and payroll system to siphon money from the organization over the course of several years, according to the U.S. Attorney’s Office. Prosecutors allege the thefts were concealed through false entries Acquista made in the EDC’s accounting system, such as fake charges for maintenance, repairs, office supplies or other recurring charges. She also put personal expenses on the nonprofit’s credit card and issued checks to herself. The total loss to EDC was $433,275.89, according to the U.S. Attorney’s Office. Acquista pleaded guilty earlier this year to a federal wire fraud charge. Court filings from both the prosecution and defense indicate Acquista has repaid the full amount of restitution requested by the nonprofit.
