Opening arguments set to begin in trial of fallen tech star Elizabeth Holmes

Opening statements are beginning Wednesday in the highly anticipated trial of Theranos founder Elizabeth Holmes, the fallen tech star accused of duping financial backers, customers and patients into believing her blood-testing startup would revolutionize medicine.

Holmes arrived at the federal courthouse in San Jose, California, amid a media scrum, a few minutes after 8 a.m. local time. She will be tried by a jury of seven men and five women, ages 19 to 60.  If convicted, Holmes could be sentenced to 20 years in prison — a stunning reversal of fortune for an entrepreneur whose wealth was once pegged at $4.5 billion. The amount represented her 50% stake in Theranos, which she founded in 2003 after dropping out of Stanford University at the age of 19.
