When an employee transferred from her position in the payroll department to human resources (HR), she was given full access to the HR databases. Her access to the payroll system should have been disabled, but was overlooked. She subsequently executed a complex scheme based on her detailed knowledge of, and access to, both systems. For almost 10 months, she modified the HR database for terminated employees to falsely indicate their rehire at higher rates of pay; modified their home address in the payroll system to her own home address; and modified their direct deposit information to direct their pay to her husband s checking account. When her fraud was detected, she had deposited approximately $198,000 into her husband s account.
