SAN JOSE >> As Elizabeth Holmes prepares to report to prison today, the criminal case that laid bare the blood-testing scam at the heart of her Theranos startup is entering its final phase.

The 11-year sentence represents a comeuppance for the wide-eyed woman who broke through “tech bro” culture to become one of Silicon Valley’s most celebrated entrepreneurs, only to be exposed as a fraud. Along the way, Holmes became a symbol of the shameless hyperbole that often saturates startup culture.

But questions still linger about her true intentions — so many that even the federal judge who presided over her trial seemed mystified. And Holmes’ defenders continue to ask whether the punishment fits the crime.

At 39, she seems most likely to be remembered as Silicon Valley’s Icarus — a high-flying entrepreneur burning with reckless ambition whose odyssey culminated in convictions for fraud and conspiracy.

Her motives are still somewhat mysterious, and some supporters say federal prosecutors targeted her unfairly in their zeal to bring down one of the most prominent practitioners of fake-it-til-you-make-it — the tech sector’s brand of self-promotion that sometimes veers into exaggeration and blatant lies to raise money.

Holmes will begin to pay the price for her deceit today when she is scheduled to begin the sentence that will separate her from her two children — a son whose July 2021 birth delayed the start of her trial and a 3-month-old daughter conceived after her conviction.

She is expected to be incarcerated in Bryan, Texas, about 100 miles northwest of her hometown of Houston. The prison was recommended by the judge who sentenced Holmes, but authorities have not publicly disclosed where she will be held.

Her many detractors contend she deserves to be in prison for peddling a technology that she repeatedly boasted would quickly scan for hundreds of diseases and other health problems with a few drops of blood taken with a finger prick.

The technology never worked as promised. Instead, Theranos tests produced wildly unreliable results that could have endangered patients’ lives — one of the most frequently cited reasons why she deserved to be prosecuted.

Before those lies were uncovered in a series of explosive articles in The Wall Street Journal beginning in October 2015, Holmes raised nearly $1 billion from a list of savvy investors including Oracle co-founder Larry Ellison and media mogul Rupert Murdoch. It was the duping of those investors that led to her prison sentence and a $452 million restitution bill.
