Whenever any person convicted of or charged with any felony escapes, or whenever any heinous crime has been committed, the governor may offer a reward of not to exceed $500 for the apprehension and delivery of such person or the conviction of the perpetrator of such crime. If such reward is claimed, whether by one or more persons, the governor shall finally determine to whom the same shall be paid, and, if to more than one person what portion to each, and shall certify the determination to the secretary of state. No such offer of a reward by the governor shall impose any actionable liability on the state.
