How do I give cash to the person who kills an npc?

If I have an npc, and when it dies, I want it to give cash, what would I add to my script? Here is my script:

function onDied()
		pose = "Dead"
		Delay(5, function()
			if script.Parent.Respawn.Value == true then
				CheckSpawns(Workspace)
				local Spawn = SpawnModel:GetChildren()
				Clone.Parent = game.Workspace
				if #Spawn > 0 then
					Spawn = Spawn[math.random(1, #Spawn)].Value
					Clone:MoveTo(Spawn)
				else
					Clone:MoveTo(Vector3.new(0, 50, 0))
				end
			end
			Figure:Remove()
			return
		end)

When the NPC Dies find the player which you have first get the weapons parent when npc died(character) then get the player from character(game.Players:GetPlayerFromCharacter(character)) then add cash to it but make sure you have leaderstats so they can get cash
