In research there is lots of news articles in italian.
In this one it seem like there is a lot of evidence that Carolina has lie in other things (google translater, is some italian speaker could reviese the article will be nice)
A summary of the article:
Contradictions between Kostner's and Schwazer's versions:
About the doping test in Oberstdorf, Kostner said it was at 7 am, Schwazer said it was at 9 am (the DCO agrees with Schwazer);
Kostner says she wanted Schwazer to talk to the DCO on the phone, Schwazer says he insisted:
She says she couldn't see the DCO's car from her window, he says he did.
Kostner says Schwazer put “medicines” in her fridge in February 2012, he says it was not before July;
WADA tested Schwazer earlier in July, but Kostner says she doesn't know about it.
Schwazer said that, in 2011, some Russian racewalkers advised him to dope, he told his then-coach, Didoni, a FIDAL doctor, and Carolina and she recommended him NOT to do it. She saw him, though, sleeping in an altitude tent.
About the meeting with Dr Ferrari, in 2010, Kostner claims that she didn't know he was a doctor, all the less a doping expert, and that she didn't perceive nothing strange in that meeting.
Attorney general doesn't believe she was so naive. Therefore, she is guilty by omission, since she should have reported Schwazer.
From another source I read, a retroactive ban seems unlikely, because Kostner was never tested positive to doping. Let's wait for January 16th.
