Nearly six years ago, William “Billy” Evans stopped by a Fleet Week charity event on a San Francisco rooftop that would change the course of his life.

Evans, 25 years old at the time, met a woman wearing a sun hat and oversized glasses and spent hours engrossed in conversation with her. It wasn’t until she gave him her cellphone number, written on the back of a Theranos business card, that he realized who she was.
