Can someone make a script the way my friend want it to be?

I am helping out a friend with a script. It is almost like TMM, but in a maze. He wants it to be this way: There are 11 players and 10 players are innocent and 1 player is the murder. The murder has 5 minutes to kill all innocent. If he kills all player then the murder wins and if he doesn't then innocent wins. For the sheriff, it will be this. He wants the sheriff's gun spawning randomly in the maze and if one of the innocent gets it, then he is the sheriff who needs to kill the murder. Just like TMM but different. He also wants the timer too. This is the script and other things in the model that I tried to make: http://www.roblox.com/Script-and-Spawn-For-a-Friend-item?id=189684938

local lobbySpawn = game.Workspace.LobbySpawn
local murderSpawn = game.Workspace.MurderSpawn
local innocentSpawn =  game.Workspace.InnocentSpawn

minimumPlayers = 11

function teleporttenPlayers(target)
    for _, player in pairs(game.Players:GetChildren()) do
            while player.Character == nil do
                wait()
            end
        local character = player.Character
        local torso = character:WaitForChild("Torso")
        torso.CFrame = target.CFrame
    end
end

function teleportPlayer(target)
    for _, player in pairs(game.Player:GetChildren()) do
            while player.Character == nil do
                wait()
            end
        local character = player.Character
        local torso = character:WaitForChild("Torso")
        torso.CFrame = target.CFrame
    end
end

function teleportPlayers(target)
    for _, player in pairs(game.Players:GetChildren()) do
            while player.Character == nil do
                wait()
            end
        local character = player.Character
        local torso = character:WaitForChild("Torso")
        torso.CFrame = target.CFrame
    end
end

while true do
    -- teleport ten players to the innocenttrack
    teleporttenPlayers(innocentSpawn)

    -- teleport one player to the murderspawn
    teleportPlayer(murderSpawn)

    -- teleport all players to the lobby
    teleportPlayers(lobbySpawn)
end 

Sorry for this. But I am learning how to script which I really need help. Thank you!
