Tenn. Code Ann. § 40-8-105

The governor is authorized to establish and administer a “reward pool fund” which shall be a special account in the state general fund. All monetary donations or gifts made by private citizens and corporations for the purpose of offering a reward or enhancing a state-funded reward offered pursuant § 40-8-101, for information leading to the apprehension, arrest and conviction of a person or persons who have committed, attempted to commit or conspired to commit a criminal offense in this state shall be deposited in the reward pool fund and invested for the benefit of the fund by the state treasurer pursuant to § 9-4-603. Amounts in the fund shall not revert to the general fund of the state but shall, together with interest income credited to the fund, remain available for expenditure in subsequent fiscal years. Except as provided in § 40-8-106, the governor shall have the sole discretion to determine if and how much of the fund shall be offered in a particular criminal case. However, if the donor places any lawful restrictions or instructions on use of the donation at the time it is given, those restrictions or instructions shall be honored.
