Elizabeth Holmes, the founder of the blood testing start-up Theranos, arrived in court on Monday for her second day of testimony. She came with her mother, Noel Holmes, and another person who has been a consistent presence alongside her at the trial: Billy Evans, her partner.
Mr. Evans’s family founded the Evans Hotel Group, a hotel chain in Southern California. He graduated from the Massachusetts Institute of Technology in 2015 and worked at a tech start-up until early 2019, according to his public LinkedIn page.
Not much is publicly known about Ms. Holmes’s relationship with Mr. Evans. The two were first seen together at the Burning Man festival in 2018, the year that Theranos shut down. Mr. Evans and Ms. Holmes, 37, had a child together in July; she often totes a diaper bag in court.
Mr. Evans often sits with the rest of Ms. Holmes’s family in their reserved row in the courtroom in San Jose, Calif., occasionally leaning over to confer with Noel Holmes during testimony. He and the other members of Ms. Holmes’s entourage keep to themselves and do not interact with the press or the public. He has declined to comment on the trial.
