Ramesh "Sunny" Balwani, the former business partner of Theranos founder Elizabeth Holmes, was sentenced to nearly 13 years in federal prison and three years of probation Wednesday for his role in the disgraced blood-test company's years of fraud.Theranos, which promised that its technology could quickly test for a variety of health conditions with just a pinprick of blood, raised hundreds of millions of dollars in investment and attracted high-profile board members before it collapsed after a series of investigative reports cast doubt on its viability.As Theranos' president and chief operating officer, Balwani had direct oversight over the company's labs, where some of the most egregious misconduct occurred, prosecutors said.Balwani knew that Theranos was not generating, and would not generate, any meaningful revenue by being honest with people,” U.S. Attorney Jeff Schenk said.“So he chose a different path.”Text messages released during the trial confirmed Balwani's outsize role."
