Charlie and Joanne Denby know the scenario first hand. The couple got a call from their grandson saying he had been arrested in Canada and needed bond money.
The couple was suspicious, but said the voice on the other end sounded like their grandson and they wanted to help, so they went to a local supermarket that offers Western Union.
The clerk at the supermarket immediately became suspicious.
"Judy called over her supervisor Regina; Regina said 'I don't like it,' Regina said, 'Let me give you the number of the U.S. Customs here in Port St. Lucie," Charlie Denby said.
That is when the couple discovered their grandson was not in jail.
Aggressive fraud prevention depends on properly educated and empowered money service employees.
But as reported last month, they are not always easy to come by.
