Check if a player died. And credit a team for it? [UPDATE]

I have a script that when a player dies it adds a value to the score board. This is a shooter game and when the player dies I found that if you continue to shoot the body until it disappears it will keep adding points.

Heres the script, I hope someone can help me out. I know it cant be too complicated, I may be over thinking it.

for i, v in pairs(game.Teams["Green Team"]:GetPlayers()) do
	v.Character:WaitForChild("Humanoid").Died:connect(function()
		RTkills.Value = RTkills.Value + 1
	end)
end

So I figured id add more of the script, because I have a feeling people may need it

So here is the whole chunk of code that this is in.

	-- Starts round and also gets players from teams
	for i = GameTime, 0, -1 do
		status.Value = i.." Time Left!"
			-- Gets Green Team and checks to see if player died, if so give red team a point
			for i, v in pairs(game.Teams["Green Team"]:GetPlayers()) do
				v.Character:WaitForChild("Humanoid").Died:connect(function()
					RTkills.Value = RTkills.Value + 1
				end)
			end
			-- Gets Red Team and checks to see if player died, if so give Green team a point
			for i, v in pairs(game.Teams["Red Team"]:GetPlayers()) do
				
			end
		if i == 0 then
			
			-- Rounds over
			status.Value = "Round Over!"
			wait(RoundOver)
			
			-- Give players points
			for _, player in pairs(game.Players:GetPlayers()) do
				if player:FindFirstChild("leaderstats") then
					player.leaderstats.Presents.Value = player.leaderstats.Presents.Value + 5

				end
			end
			break
		else
		end
		wait(1)
	end

Its in a team script because its a shooter and so when someone on that team dies it adds a point. But again its triggering more than once.

Thank you for your time :)

IF you keep shooting the Humanoid. I suggest you have a value if the player is dead or not, and check that before rewarding the kill.
