What is this story exactly and where can I read more about it?

I overheard parts of this recent crime story, told by its victim on a program last night. This middle aged American woman (?) talks about how she was scammed by a man in Italy (?) who claimed to be personally connected to the Pope, and promised to arrange her wedding in Rome (?) with the Pope himself as their clergy. He even claimed to have taken care of the details such as the venue and booking. I think about a day or few before the wedding, this woman started discovering there was no evidence or trace of any such wedding arrangements, despite the fact that the couple got themselves prepared, and they had 300 guests who'd already booked travel arrangements to come. I didn't catch much more beyond that, but I also vaguely heard the mention of a house in Barcelona that someone didn't want her to see, because there was something in it, connecting to the story, that was deliberately being hidden from her. The last thing I caught her saying was that she went to Rome and to the Barcelona house to find some things out.
