Mo. Rev. Stat. § 104.490

104.490. Correction of errors in amount paid members — falsification of records, penalty — survivor or beneficiary charged with killing member, denial of benefits, resumption of payments if not convicted. — 1. Should any error result in any member or beneficiary receiving more or less than he or she would have been entitled to receive had the error not occurred, the board shall correct such error, and, as far as practicable, to recover any overpayments, may accept single sum or installment repayments or make future payments in such a manner that the actuarial equivalent of the benefit to which such member or beneficiary was entitled shall be paid. In all cases in which such error has been made, no such error shall be corrected unless the system discovers or is notified of such error within ten years after the member's annuity starting date or the date of error, whichever occurs later. In cases of fraud, any error discovered shall be corrected without concern to the amount of time that has passed.

2. A person who knowingly makes a false statement, or falsifies or permits to be falsified a record of the system, in an attempt to defraud the system is subject to fine or imprisonment pursuant to the Missouri revised statutes.

3. The board of trustees of the Missouri state employees' retirement system shall cease paying benefits to any survivor or beneficiary who is charged with the intentional killing of a member without legal excuse or justification. A survivor or beneficiary who is convicted of such charge shall no longer be entitled to receive benefits. If the survivor or beneficiary is not convicted of such charge, the board shall resume payment of benefits and shall pay the survivor or beneficiary any benefits that were suspended pending resolution of such charge.
