Stopping a function until a targeted(killer) player has died?

So I'm trying to stop this while true loop until the killer has died. Then when the killer has died, it will go back up and continue the loop once more. Here is my script. I'm trying to add the "killer has died" script part at the end:

``

game.Players.PlayerAdded:Connect(function(plr) plr.CharacterAdded:Connect(function(char) while true do local players = game.Players:GetPlayers() local killer = players[math.random(1,#players)] print(killer)

		--edit chosen player--
		local hat = game.ServerStorage.SpartanHelmet

		killer.Character.Humanoid:RemoveAccessories()
		killer.Character:WaitForChild("Shirt").ShirtTemplate = "http://www.roblox.com/asset/?id=11356448"
		killer.Character:WaitForChild("Pants").PantsTemplate = "http://www.roblox.com/asset/?id=11357134"
		local hatclone = hat:Clone()
		killer.Character.Humanoid:AddAccessory(hatclone)

		--add speed,health and jumpheight--
		killer.Character.Humanoid.WalkSpeed = 24
		killer.Character.Humanoid.MaxHealth = 200
		killer.Character.Humanoid.Health = 200
		killer.Character.Humanoid.JumpHeight = 10

		--show players name--
		local swordsmansign = game.ServerStorage.SwordsmanSign:Clone()
		swordsmansign.Parent = killer.Character:FindFirstChild("Head")

		--show killers picture--
		local Players = game:GetService("Players")
		local board = game.Workspace.Board.board.SurfaceGui.ImageLabel
		local userId = killer.UserId

		local thumbType = Enum.ThumbnailType.HeadShot
		local thumbSize = Enum.ThumbnailSize.Size420x420
		local content, isReady = Players:GetUserThumbnailAsync(userId, thumbType, thumbSize)

		board.Image = content
		board.Size = UDim2.new(0, 420, 0, 420)


		--show killers name--
		local label = game.Workspace.LabelPart.SurfaceGui.TextLabel
		label.Text = killer.Name

		--mapchange--
		local function selectmap()
			local maps = game.ReplicatedStorage.Maps:GetChildren()
			local selected = maps[math.random(1,#maps)]
			return selected
		end

		local randomizedmap = selectmap()
		print(randomizedmap)

		local randomizedmapclone = randomizedmap:Clone()
		randomizedmapclone.Parent = game.Workspace.Map
		-------------------------------------------------------Im trying to put the killer died here
		killer.Character.Humanoid.Died:Connect(function()
			print("killer died")
		end)
	end
end)

end)
