Hamilton's defence: The vanishing twin?

By Susan Westemeyer, with additional reporting from Cyclingnews staff

With a verdict in the Tyler Hamilton blood doping case expected today (Monday), information has already started to leak out about the likely outcome of the case, and the nature of Hamilton's defence. In an article in the Los Angeles Times, it appears that the "vanishing twin theory" is being used to try to explain the mixed blood cell population in Hamilton's body. "A theme central to Hamilton's defence is the notion of a 'vanishing twin' who shared the womb when Hamilton was a fetus - a point on which there is much speculation but no proof," wrote the LA Times, which said it had "obtained key documents before the arbitration panel, including legal briefs, test results, and the transcript of the hearing six weeks ago where the U.S. Anti-Doping Agency and Hamilton's defense team presented their cases." These documents likely did not come from the UCI or the USADA, who typically don't release these to the media.
