Two culprits are involved; one will approach a victim, usually in a public area such as a shopping center, and strike up a friendly conversation, the second will approach telling of a large sum of money or valuables that were found. The victim, the "new friend" and the "finder" agree that the money or valuables will be split, but only after the victim, the "new friend" and the "finder" put up money as a sign of good faith. Once this is done, the good faith, the money and the new-found friend will rapidly disappear.
How to Avoid
Do not turn any money over to strangers looking for a quick profit.
Greed can blind you. Don't expect something for nothing.
