We have a variation of that going on here. They use real names of you your relatives AND the names of upper management of the Sheriffs Office. They ask for Gift Cards for a similar reason and then have you send it to an address in another State, then as a kicker set up an appointment at the Sheriffs Office with a Colonel or Major that really works there to discuss getting the charges dropped. The appointments are always the same time, so there is a line of older folks that show up to talk to this person. Often times they have to take a cab to get there. The SO explains to them what has happened, most times tears are involved, gives them a card of that person they were directed to talk to with instructions to call them if they ever get another call, before they pay them anything. Then they call a car in to take them home.
These people are scum that do that, and Bent, I am sorry that happened to your mom....you just want to find these guys and pummel them. The scams are as old as telephones themselves....I dealt with them constantly in the little town I worked in.
