The goodwill payment to Ambrosiano creditors from the coffers of Opus Dei did not close the criminal probe of the massive bank collapse. On February 26, 1987, the investigating magistrates concluded that the Vatican Bank had acted as an umbrella for Roberto Calvi’s illicit transactions, that it owned a substantial share of Banco Ambrosiano as well as the dummy corporations, and that it was responsible for the theft of $1.75 billion. Arrest warrants were issued for the three top IOR officials: Archbishop Paul Marcinkus, Luigi Mennini, and Pellegrino del Strobel.
