Got the same one yesterday. I was threatened by this person. I called one time and no name for voice mail, call right back and John Marsh, again John Hill voice mail. I was able to find post of this same scam from 2013. Just look up John Marsh and this number.
I got a call from this number and a recorded lady's voice said, "A case has been made against you. You will soon be arrested. For more information call 714-646-7334. See you at the courthouse." Of course I did not call. But I felt like it should be reported. I see that others have been getting the same call.
