Over the past few days, jurors in Theranos founder Elizabeth Holmes’ criminal trial have been hearing about the now-infamous demos given to Theranos investors. The devices would make noise but not produce results, they ran apps that blocked error messages from appearing, and in some cases, instead of tests happening in front of visitors, blood samples were taken elsewhere for analysis.

Yesterday, the picture resolved itself further as testimony from Daniel Edlin, a product manager who was friends with Holmes’ brother Christian, continued. Edlin revealed that Holmes herself and Daniel Young, a Theranos scientist and vice president, played key roles in what ultimately transpired during demos for visitors and investors.
