In a day of intense and emotional testimony, Theranos founder Elizabeth Holmes told the court of the sexual, physical, and emotional abuse she said she suffered at the hands of company president and chief operating officer Ramesh “Sunny” Balwani and others.

Balwani was Holmes’ boyfriend for more than a decade, much of it during their time leading Theranos, the failed blood-testing startup. The pair hid their relationship from investors and Theranos employees. Balwani has pleaded not guilty to the same fraud and conspiracy charges Holmes faces. His trial begins next year.

Holmes’ attorneys said she met Balwani in 2002 on a language-immersion trip in China. She was 18 years old at the time and a senior in high school. He was in his late 30s and pursuing an MBA at the University of California, Berkeley.
