The criminal fraud case of Elizabeth Holmes' former second-in-command heads to jury

The criminal fraud trial of Elizabeth Holmes' ex-boyfriend and former second-in-command at Theranos is heading to the jury, roughly three months after it kicked off in the same San Jose, California, courthouse where she was found guilty on four charges of defrauding investors.

In closing arguments, which began Tuesday and spanned nearly four days, the prosecution sought to highlight the many ways in which it alleges former Theranos COO and president Ramesh "Sunny" Balwani directly helped defraud investors and patients alongside Holmes over the course of several years. Prosecutors pointed to various emails, text messages and witness testimony reviewed during the trial that highlighted Balwani's integral roles at the company and his intimate knowledge of the startup's failings.

The defense, meanwhile, argued the government had cherry-picked information and lacked sufficient evidence to prove its case. It ticked off the many high-profile people who, like Balwani, were said to believe in Theranos and Holmes, and who, like Balwani, invested time and money in the business.
