What's in this script that makes the vehicle fall apart if the player who was in the seat dies?

function onChildAdded(part)
if part.className == "Weld" then
	local torso = part.Part1
	if torso ~= nil then
		local parent = torso.Parent
		if parent ~= nil then
			local player = game.Players:findFirstChild(parent.Name)
			local turret = script.Parent.Parent.Parent.Parent
			turret.Parent = parent
			local tool = script.Turret:Clone()
			tool.Parent = player.Backpack
			script.Parent.Sound:play()
		end
	end
end
end


function onChildRemoved(part)
local player1 = game.Players:findFirstChild(script.Parent.Parent.Parent.Parent.Parent.Name)
player1.Backpack.Turret:remove()
script.Parent.Sound:stop()
end

script.Parent.ChildRemoved:connect(onChildRemoved)
script.Parent.ChildAdded:connect(onChildAdded)

This is the script for it, and if a player gets in the seat, then later dies, it falls apart as if it was exploded. Problem?
