How do you end a round when a player kills an NPC in Roblox Studio?

Hello, I am currently making a game in which players are put in this map where they have to kill an AI character. So far, I have everything finished for the scripts except when the players kill the NPC and the game ends. I don't have a very well knowledge of this, and I really need this help to upload the game. To be exact, I need a continuation of this script (in the post) that will end the round(say something like "Player2 has killed the Murderer" as well) when a player kills the NPC, and after, all players will be taken to the lobby(spawnlocation pad). Please reply as soon as you can.

This is the script so far:

local replicatedstorage = game:GetService("ReplicatedStorage")
local status = replicatedstorage:WaitForChild("StatusValue")

while true do
-- Intermission
for i = 30,0,-1 do
status.Value = "Intermission: "..i
wait(1)
end
status.Value = "Game in progress"
local map = game.ServerStorage.BaseMap
map:Clone().Parent = game.Workspace
wait(15)
game.Workspace.BaseMap:Destroy()
status.Value = "Game Over!"
end

If there are any issues with this script, please be sure to comment on it as well. Thank you!
