An audit says the Assessment Division of Detroit's Finance Department can't account for $310,000 in cash receipts over four years.
The audit says a department employee with almost no operational controls and access to a cash register diverted the money for someone's personal use.
The report by the city auditor general's office says the cash disappeared from the division's cash register since 2007.
The audit says no one noticed the disappearance of the money because the finance department has no effective citywide cash management policy.
City Council member Ken Cockrel says "it's hard not to come to the conclusion that leadership in this division was asleep at the switch."
