Lawyers Make Final Arguments in Fraud Case Against Former Theranos President

Government prosecutors in the criminal-fraud trial of Theranos Inc.’s former second-in-command, Ramesh “Sunny” Balwani, made their final pitch to the jury in closing arguments Tuesday, as the Silicon Valley case moves closer to a resolution.

Assistant U.S. Attorney Jeff Schenk said that Mr. Balwani, longtime president and chief operating officer of the now-defunct blood-testing startup, had full knowledge of the fraud he was committing because he was in charge of Theranos’s laboratory and was well-informed of its many problems with test accuracy and reliability—and fired employees who raised concerns.
