All that is known so far is that TechCrunch confirmed that the Vice President of Communication at distressed Theranos, Brooke Buchanan, left last Friday. Here is the coverage.
Neither Buchanan nor Theranos founder Elizabeth Holmes has responded to TechCrunch's request for comment. At least not yet.
One of Buchanan's last announcements was that Holmes would be disclosing the workings of the startup's technology at the American Medical Board of Clinical Chemistry (AACC) conference. That was scheduled for August. Since then Holmes backed off.
Superlawyer David Boies has been on the Theranos board and is "advising" Holmes. That is one of the myriad factors which gives this story legs.
Theranos had been the darling of media until last October. It was then that The Wall Street Journal broke the story of questions about the accuracy of the supposed game-changing technology. After that, there was a media pile-on.
Meanwhile, federal agencies are investigating Theranos, including for possible criminal wrong-doing. Walgreens pulled out as a partner.
