Elizabeth Holmes, the disgraced Silicon Valley star and founder of blood-testing startup company Theranos, has been found guilty on four of 11 charges of fraud, with a maximum sentence of 20 years in prison. The jury found her not guilty on four other charges, and failed to reach a verdict on three more.

Holmes, who was once considered “the world’s youngest self-made female billionaire,” has been at the centre of a high-profile trial investigating whether she intentionally misled investors, doctors and patients as she collected multi-million dollar investments in her company, which promised to map patients’ health and detect conditions such as cancer and diabetes with just a small amount of blood.
