Theranos trial: Prosecution rests, Elizabeth Holmes takes the stand

The trial of former Theranos CEO Elizabeth Holmes is reaching a crucial point.

The prosecution rested its case on Friday after calling nearly 30 witnesses over the past two months.

She’s expected to testify further Monday.

Holmes ischarged with multiple countsof conspiracy and fraud over claims she made about the company’s compact blood-testing machine.

Investigations revealed the technology had serious problems.

Since September, federal prosecutors have attempted to make the case that Holmes misled patients and investors.

Then the defense called Theranos board member Fabrizio Bonanni to the stand.

Next it was Holmes' turn, though her attorneys hadn’t made prior indications she’d testify.

Here’s what else to know about one of the biggest trials of the decade so far.

What happened to Holmes and Theranos?

Theranos began to see more mainstream attention in 2013 when it signed up Walgreens and Safeway as potential customers.

At one point, the startup was valued at more than $9 billion.

The accuracy of test results that patients received from Theranos was also called into question.

Former Theranos employee and whistleblowerTyler Shultz spoke with CNETin 2020 about the whole saga.

Holmes isformally chargedwith two counts of conspiracy to commit wire fraud and 10 counts of wire fraud.

If convicted, Holmes could be sentenced to up to 20 years in prison.

The 37-year-old reportedly pursued a book deal to get her story out.

Holmes' lawyers come from the high-powered Washington firm that defended President Bill Clinton at his impeachment trial.

Lawyers for Balwani called abuse allegations “outrageous.”

The trial officially began Sept. 7, with opening arguments the following day.

Balwani faces similar charges in a separate trial scheduled for next year.

Both Holmes and Balwani have pleaded not guilty.
