"But investigators say that the faith was also a large part of how Rust ran his operation; he allegedly used his relationship with the church to exploit individuals into investing in his fake silver pool. Court documents allege that he gained their trust by being a member in high standing, often getting those in his local ward to contribute and encouraging them to get other members of the faith involved.

And, court documents allege, he pointed to his generous contributions to the church as a means to bolster his credibility and suggest that the investment would make them just as wealthy and able to give more in tithing to their shared faith. In the church, members are expected to donate 10% of their income.

According to state and federal law, any money that was collected through illegal means, and then donated, must be returned.

The LDS Church has entered into a settlement agreement to pay the $2.4 million to the receiver so that the money can be returned to investors."
