Why can't the client destroy my model?

Ok so I have a humanoid model in workspace called "Noob" and have a script that plays an animation then destroys it when they die, Problem is that the client can't seem to get rid of the model and manually deleting it seems to just deselect it. The script is here:

local walk = script.Parent.Humanoid:LoadAnimation(script.Walk)
local idle = script.Parent.Humanoid:LoadAnimation(script.Idle)
local attack = script.Parent.Humanoid:LoadAnimation(script.Attack)
local ded = script.Parent.Humanoid:LoadAnimation(script.Death)
local running = script.Running

script.Parent.Humanoid.Running:Connect(function(speed)
	if speed <= 0 then
		running.Value = true -- I have no clue why but this is reversed :/
	else
		running.Value = false
	end
end)

running.Changed:Connect(function()
	if running.Value == true and script.Parent.Humanoid.Health > 0 then
		idle:Play()
		walk:Stop()
	elseif script.Parent.Humanoid.Health > 0 then
		walk:Play()
		idle:Stop()
	end
end)

script.Parent.Attack.Event:Connect(function(target)
	if script.Parent.Humanoid.Health > 0 then
		attack:Play()
		script.Parent.HumanoidRootPart.CFrame = CFrame.new(script.Parent.HumanoidRootPart.Position,target.Position*Vector3.new(1,0,1) + script.Parent.HumanoidRootPart.Position*Vector3.new(0,1,0))
	end
end)

script.Parent.Humanoid.Died:Connect(function()
	walk:Stop()
	idle:Stop()
	attack:Stop()
	script.Parent.Humanoid.WalkSpeed = 0
	script.Parent.HumanoidRootPart.Anchored = true
	ded:Play()
	spawn(function()
		wait(0.8)
		script.Parent:Destroy()
	end)
end)
