'Taxpayers should be outraged': Missouri releases audit of Kim Gardner's office The audit said Gardner oversaw a steep decline in cases processed and a significant increase in the length of time needed to dispose of cases. According to the audit, Gardner’s office took an average of 463 days to dispose of a case. That was 170 days longer than the preceding administration and more than double the current administration's average of 142 days. The Missouri Supreme Court recommends prosecutors clear 95% of case within 14 months, but Gardner’s office failed to do that, the audit said.
