Transcript for Where Elizabeth Holmes is today: Part 11
Reporter: Once a blazing star, Elizabeth Holmes has all but disappeared from the public eye. I never really expected to ever see her again in person. Reporter: Michael Craig had only heard whispers about his former boss until one chance encounter at a bar in sausalito. I looked over to my left, and at a bar table, staring right at me, I realized it was Elizabeth Holmes. And then she got up and came over. Reporter: But she wasn't the poised woman he once revered. She looked like a fraction of that former self. She was always in the Steve jobs black thing. Always very made up. She didn't have any makeup on. She was in a dark hoodie and jeans. She introduced her friend as her fianc??. And I was like, "I wonder what story she has been telling him, and herself, really." Reporter: The Elizabeth Holmes story has had an undeniable impact on those left in her wake. Like whistleblower Tyler Shultz. He and his grandfather, George Shultz, have since made amends. The former theranos board member, told ABC news that his grandson, "Did not shrink from what he saw as his responsibility to the truth. Even when he felt personally threatened and believed that I had placed allegiance to the company over allegiance to higher values and our family." As for Tyler's confidant John carreyrou, he wrote a bestselling book, "Bad blood." ?????? but what remains to be seen is whether the story of Elizabeth Holmes is one of misguided ambition or deliberate deceit. There is this argument that she's trying to change the world, and it's not easy to change the world. We could all have a great idea. We're going to have a car that flies tomorrow. That's a great idea. The great ideas are a dime a dozen, but it's how you implement them. Do you think it's humanly possible that Elizabeth Holmes wasn't aware of what was going on at her company? No. No. She knew what was going on. So many people wind up in jail for little things. This is not a little thing. Reporter: To this day Elizabeth Holmes denies any wrongdoing. Last I heard about Elizabeth Holmes is that she is currently in silicon valley, trying to start a new company and seeking funding for it. Was Elizabeth a sociopath? I think history speaks for itself. Reporter: As Elizabeth herself once declared at a Forbes conference, Elizabeth Holmes is not a woman who will go down without a fight. You will get knocked down over and over and over and over again and you win by getting back up. I would start this company over 10,000 times if I had to.
