One of the lab techs testified she knew the sample was Landis's.

So much for the lab's rule about confidentiality and blind testing.
However, Greg LeMond has testified that Landis has admitted he doped up. Worse, he has accused Landis's uncle of witness tampering, threatening to reveal that LeMond had told Landis about being molested as a child, and that the way to break from that was to admit the truth (i.e., that Landis had doped up. Apparently the uncle intended to coerce LeMond so he would not testify.
The article does not quote LeMond's testimony constituting the admission. In fact, what this article recites is more ambiguous. ("What good would it do?") There may be testimony the article did not include, so the issue remains murky from here.
