Son ends Stolen Goods "torture"

Perhaps Peter Tompa will still cling to his unreasonable theory about some conspiracy between FBI agents and "the Italians", but there is another story from an Atlanta paper about the recent Sisto case which is stronger on the 'human interest' and letting slip more about the deceased man's knowledge and involvement than the initial reports.

These things are three-times cursed, Sisto, of Duluth, would tell his father, John. Cursed once because they were stolen, cursed twice because they were smuggled, and cursed thrice because concealing the cache in their home had robbed the family of its peace of mind.
“It didn’t feel right. It never felt right,” Joseph Sisto said. “To me, having the stuff was always a burden.”
Now, after a lifetime of secrecy, Sisto, 48, finally feels a burden has been lifted. Early last week, the FBI announced the conclusion of its two-year investigation into the theft and transportation of the artifacts.
For more than 20 years, John Sisto, of Berwyn, Ill., amassed a collection of more than 3,500 precious antiquities that would have been the envy of any museum curator.
Just about every piece of it had been looted from historic Italian sites or stolen from private collections, the FBI said. The elder Sisto knew it when he bought the goods, the agents said. Joseph Sisto agrees.
In fact, after his father died two years ago, it was Joseph Sisto who finally picked up the phone and called the police to tell them about the treasures that filled nearly every corner of the house in Berwyn.

The rest here. Joseph Sisto does not really sound from this like the sort of person easily "indoctrinated" as Tompa suggests.
