She said Malone pleaded the Fifth Amendment regarding questions on attendance data and procedures and credit card purchases.

Malone’s attorney did not respond to a request for comment Tuesday.

The audit also said there was not enough supporting documentation for purchases totaling $13,916 by school personnel, including food, hotel stays, a vacation package and several Amazon purchases.

The audit said employees in many cases submitted a credit card charge slip or credit card statement but no invoice. Without actual invoices, the audit said, it can’t be determined whether purchases were of legitimate school-related items or personal items.

Regarding attendance data, the $1.4 million in overpayments totaled by the audit were for the 2016-17, 2017-18 and 2018-19 school years.

The audit found that the school inflated attendance figures by improperly claiming remedial and summer school hours. The school also inflated individual student attendance hours, the audit found.

The audit began after an internal review uncovered the artificially boosted attendance records. The internal review said the potential total overpayments, going back as far as 2011-12, could have reached $2.36 million.
