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)
