SAN JOSE, Calif. (AP) — Fallen Silicon Valley star Elizabeth Holmes has been convicted of fraud for turning her blood-testing startup Theranos into a sophisticated sham that duped billionaires and other unwitting investors into backing a seemingly revolutionary company whose medical technology never worked as promised. A jury on Monday convicted the 37-year-old on two counts of wire fraud and two counts of conspiracy to commit fraud after seven days of deliberation. The verdict followed a three-month trial featuring dozens of witnesses — including Holmes herself. She now faces up to 20 years in prison for each count, although legal experts say she is unlikely to receive anything close to the maximum sentence.
