I think this story is intriguing because of the possibilities, not because of the scant details. It's a fact that Popovych was subpoenaed for and testified to the grand jury. The serving of the subpoena was kind of dramatic. Then there was the rumor that Novitsky was getting ready to head to Europe. So even though there might not be any connection between those events, and I haven't seen the Novitsky thing confirmed, trying to make a connection between things gives me a glimmer of hope that the investigation is going well, and that we'll see similar stories around Europe.
On a slightly different topic, weren't there still unnamed pro cyclists who were persons of interest in the Cobra Red thing? I didn't know until today that Popo lived in Tuscany, but could he maybe have been a customer of Ricco's inlaws?
