FRAUD ALERT!!!!  Caller phoned my senior mother, purporting to be her grandson whose friend was caught with cocaine in Bolivia, needing $4950 for bail.  Told her not to tell anyone about the call, where to go (in her town) to send the money, and to do it within the next 1 1/2 hours.  He gave her this number for the American Embassy in La Paz, telling her to call there for authentication.  Luckily the bank would not allow withdrawals of this size.
