There is another article on a different newspaper (el pais, which a recognized and respectable outlet) with a case that sounds too much like this one but with different numbers.
In this case it was one elder, who talked a bunch of other elders into an investment with huge returns. In this case they are talking of about 70 million euros, which is close to the 80 million the other case claims was kept in Swiss banks. In this case the money was also transfered to a swiss bank but they were actually paying back interest to the investors (about 2500 individual brothers invested) until the money flow stopped. One brother claims the instigator was traveling around congos looking for wealthy people. Some investors got money together with their family in upwards of 49,000 euros. Some of the numbers, regarding the number of elders and the sentence to those who got caught, match the case mentioned in this thread. Also, the fact that they only caught the secondary criminal but the mastermind is on the run (just like the first article on this thread)

This other one claims the mastermind was a witness but only 700 out of more than 2000 investors were witnesses

In any case all these articles are no more than 2 months old. I guess we will hear more.
