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)
