This number is a man from Jamacia running a money scam (lottery scam).  He is posing as a "secret service" trying to bust the Jamacian bad guys.  He has been fleecing my elderly mother over the past 9 months ($16,000).  He even has her doing some money laundering (receiving money transfers from othe victims and forwarding the transfer to Jamica).  She is believing he is on the side of the law when in reality she is being conned.
