The character is falling, as it hits the ground some parts should spawn, they spawn way above, why?

This is the script:

wait()

script.Parent.OnServerEvent:Connect(function(player)

    local character = player.Character
    local melee = player.PlayerStats.Melee.Value

    if character.HumanoidRootPart:FindFirstChild("BodyVelocity") ~= nil then
    character.HumanoidRootPart.BodyVelocity:Destroy()
    end

    local bdv = Instance.new("BodyVelocity",character.HumanoidRootPart)
    bdv.Name = "bdv"
    bdv.Velocity = Vector3.new(0,-90,0) * (melee/30 + 5)
    bdv.MaxForce = Vector3.new(99999,99999,99999)

    local td = game.ReplicatedStorage.Objects.TouchDetector2:Clone()
    td.Parent = character.HumanoidRootPart
        td.CFrame = character.HumanoidRootPart.CFrame

    local weld = Instance.new("Weld",td)
    weld.Part0 = td
    weld.Part1 = character.HumanoidRootPart

    td.Touched:Connect(function(hit)

        if hit.Anchored == true then




            character.HumanoidRootPart.Anchored = true

            td:Destroy()

            local cfr = character.LowerTorso.CFrame


            local cr = game.ReplicatedStorage.Objects["Cracks and rocks"]:Clone()
            wait()
            cr.Parent = character.LowerTorso
            cr.Size = Vector3.new((melee/5)+10,(melee/5)+10,(melee/5)+10)
            cr.CFrame = cfr





            wait(1)

            bdv.Velocity = Vector3.new(0,90,0)
    bdv:Destroy()
        character.HumanoidRootPart.Anchored = false



        end





    end)


end)

So the character is falling down faster than normal cause there's a body velocity making it go down. Now that part's CFrame should be the same as the HumanoidRootPart.CFrame as it hits the ground, but instead the CFrame of the part is well above the character. Any ideas how to fix that?
