Audio still plays after being removed?

I'm using an OnTouched script to play a sound. The problem is, once the model the sound is located in is removed, it continues to play. I need for the sound to stop playing once removed. No, PlayOnRemove is not set to true. Can anybody help with this? Here's my code...

Sound = script.Parent.Sound
active = false
function onTouched(hit)
	if active == false then
		Sound:Resume()
		active = true
	end
end
connection = script.Parent.Touched:connect(onTouched)

You have to loop it for god knows why.
