Another $65,000 was spent on a database system called Evalis that "identifies at-risk behavior activities of officers." Evalis also was never used, partly due to the need for additional software and services, but once again because the original vendor also went out of business, according to the report.

Finally, about $37,000 has been spent on a software package from SAP that has yet to be implemented, and the department is still using the legacy system, "which is currently out of warranty," the report states.

An Oakland police spokesperson didn't immediately respond to a request for comment.

In a statement attached to the audit, city administrator Deanna Santana said its recommendations, which call for better training and IT planning practices, are "generally sound."

However, the audit contains a number of "significant errors and omissions," Santana added.
