Edgardo ultimately settled at the Abbey of the Canons Regular in Bouhay, Belgium - near Liege. Highly educated, he spoke six languages. Edgardo was a world-famous priest who never ceased to tell the story of how an illiterate servant girl rescued him for the Catholic Church. He rarely saw his family.
He died (aged 88) at the Bouhay Abbey in 1940, two months before Nazi soldiers swooped into Belgium. Edgardo, who had taken the name Pio (Pius) after his mentor, the Pope, was barely dead when Nazis began to send Belgian Jews to death camps.
The Italian Inquistitor, Father Feletti, was ultimately tried for issuing the order to kidnap Edgardo. Once Bologna was out of church hands, the secular courts were free to proceed as they would against anyone accused of kidnapping.
Bologna may have been out of church hands, but the judges who decided cases were not technically out of church control. The court was bound to rule based on laws in effect at the time of the alleged crime, not laws in effect at the time of trial.
A panel of six judges decided the Inquisitor had followed the law in effect at the time. Father Feletti, jailed fifteen weeks in a cold Bologna tower without a window, was freed. The court held:
...there were not, and are not, grounds for proceeding criminally against the executors of the above-mentioned action [the taking of Edgardo], and thus against the defendant Pier Gaetano Feletti of the Order of Preachers, formerly Inquisitor of the Holy Office in Bologna. Consequently, he should be immediately released from jail.

No longer an Inquisitor, Father Feletti was still a Dominican who had endeared himself to the Pope. He was sent to
Rome where he was in charge of a Dominican convent until he died in 1881. He was 84.
