1. The costs of any investigations shall be paid from the reimbursements secured pursuant to the provisions of sections 217.825 to 217.841.

The provisions of section 33.080 notwithstanding, moneys in the inmate incarceration reimbursement act revolving fund shall not lapse, be transferred or appropriated to or placed to the credit of the general revenue fund or any other fund of the state.

2. The state treasurer may determine the amount due the state for the cost of care of an offender and render statements thereof and such sworn statements shall be considered prima facie evidence of the amount due.
