It was David Grey who "warned" me. This is the 9th time these jerks have called since May, always with the same message, same voice, different name given each time. Shockingly, I have not been arrested or contacted by the police/Feds/LEO. Even more shockingly, googling brought me to an article from January where a scammer used the exact same message.
This is the third or fourth call I've received from this person over the past year. Every couple of months he changes his number, but I recognize the same foreign accent for each call. He claims to be from the US Treasury Department or from the IRS. The last time he called he claimed his name was "Dennis Quaid". He seems to have a penchant to name himself after famous actors. Ha!
