The sheriff or other officers who shall arrest anyone who kills another and is fleeing, or attempting to flee, shall be entitled to the reward provided for in Section 99-3-35 the same as other persons, provided the killing is not done in the county in which the officer making the arrest resides. But the court adjudging such award to be due may, in its discretion, order the reward to be divided equally between the officer making the arrest and any person or persons, giving him information leading to such arrest.
