After three years of employment with a Las Vegas casino, Bill Whaling was promoted to operations manager. He was happy with the promotion, but had immediate concerns about the internal controls in the casino's cage. The cage manager, Betty Brown, was reluctant to provide access to, and share details about, cage operations.
The cage in a casino is the financial center of all operations. It routinely makes change, cashes checks, and checks slot machine access keys in and out. It also receives funds from drop teams collecting coins and currency from slot machines and gaming tables, verifies jackpots paid, fills slot machines, and makes bank deposits of gaming revenue and ancillary revenue from the bar, cafe, and hotel. An internal auditor always independently verifies payouts.

Though unconcerned initially, Neil and Harper saw Brown's check amounts growing with no sign that she would return the money as promised. Unable to handle the pressure, they approached Whaling to notify the owners.
Brown had been in charge of reconciling the cage department records with the underlying fund balance of the vault. Both independent semiannual audit findings and required triennial state gaming control board audits had listed this as a material weakness in internal controls. Whaling also had expressed his concerns about the issue. However, the owners were satisfied with filing exception reports with the state gaming control board to maintain compliance with the Minimum Internal Control Standards on the grounds that this was a small operation, nothing serious had...
