They probably won't leave a message, but if they do, DO NOT CALL these people back.  IT IS A SCAM!!  It is the "it's me" scam where they call (usually the elderly) and say they are a relative and need money.  This particular one was a call to my father and the caller said he was his grandson and needed bail money and not to tell his parents!!  Then a "Sgt. Cooper" comes on and tells him if he'll send $2000 bail money within a couple of hours they won't file "felony drug" charges and then when he sees the judge in the morning he can either get the charges reduced or dropped, but if they don't get the bail money right away they will have to file the "felony" charges and it will go on his record, he'll lose his job, and he'll be in a lot of trouble..   SCAM!!!  I've heard sometimes they use "accidents", or they need help getting out of a foreign country and they'll pay them back as soon as they get home..  It can be a child, grandchild and I've even heard them use niece or nephew.
