Did anyone stop to think that the paper was just something saying there was no official ruling yet and he was simply under investigation rather than coming here and suggesting it was something forged? Nyman doesn't appear in the SafeSport disciplinary database, and Sappenfield just showed up 'officially' on the 14th per their website.
If Savchenko wasn't following skating news closely as people who read message boards do, it's quite possible that she was told by other people even aside from Nyman that he was just a person of interest and maybe he and Dalilah stated the same, or maybe they said it was all baseless-- who knows. We know the USFS was quick to push for her to skate for the country, so I don't think it's that out of the question to not be 100% in the loop.
