MONTPELIER, Vt. (AP) - An independent audit of the Vermont State Police payroll requested after a trooper fraudulently claimed large amounts of overtime pay has found that the process for approving, reporting and monitoring overtime is vulnerable to fraud, abuse and waste.

The audit done by StoneTurn Group LLP says the state is planning to implement a new payroll reporting system that is likely to address some of the problems.

The audit recommends that the state implement detailed reports to monitor overtime and criteria to limit overtime amounts have periodic independent reviews done to look at whether overtime is or was required.

It also found that supervisors provide "rubber stamp" approval of time reports and perform inadequate review.

It recommends requiring supervisors to do overviews of overtime and to hold them accountable for errors.
