How to talk to an NPC with an uncertain location?

My Quest needs to talk to an npc, but this NPC doesn't have an accurate XYZ. How can I find this NPC accurately?   

NPC is within a certain range

Hello, if distance between know positions is high, you can try to use quest type interactwithnpc (with several hotspots)

but there is no accurate positions,   For example, after killing, it will become an npc and then talk to npc, because the location of the kill is uncertain, so the position of the npc is also uncertain.

With several hotspots you cannot found npc? if yes you need to use c# code
