Blood money for intentional killing if the killer dies and has no estate

Question:
A bad situation. In the case of a slave who kills, if he dies and he has no estate, does the liability fall on the 'aqilah? And in the case of a slave who kills by negligence, if he dies, does the liability fall on the 'aqilah?

Answer:
No, the blood money for intentional killing is on the killer. If he dies and he has no estate, the place from which the blood money is paid is lost. It may be said that it is paid from the public treasury. If it is not possible to secure it from the offender’s estate, it is paid from the public treasury. Yes.
