You gotta wonder about that. A few months ago I was at my mom's house and someone called and said, "Can I speak to Grandma." To make a long story short, I gave the phone to my mom who told me that it was my nephew calling from a jail in Mexico. He said he had been arrested and needed her to wire him some money. She is handicapped and told him he would have to call back in an hour when my dad was there to help her wire the money.
After calling my sister, we determined that my nephew could not be in Mexico and was in fact at work in Georgia. I immediately called the local police and told them that this person was probably randomly calling asking for Grandma, hoping to get old people and tricking them into wiring money. They told me not to worry about it.
I explained that the person was going to call back in an hour and did they want to cover over or do something to try to determine where the call was coming from. They said no it was too hard to track.
The following week in the paper I read about a senior citizen in my mom's neighborhood who was swindled out of $2,000 because someone impersonating his grandson called and requested money to be wired to get him out of trouble.
Now, if the cops had at least tried to do something maybe this man would not have lost $2,000.
Ever hear of a phone tap? Geeeze. They had them way back in the 60's
