Former Walgreens CFO testifies about pharmacy’s troubled partnership with blood-testing start-up Theranos

SAN JOSE — The former chief financial officer of Walgreens took the stand for his first full day of testimony at the trial of Theranos founder Elizabeth Holmes, a key government witness in the case surrounding the failed blood-testing start-up.

Wade Miquelon told prosecutors that Theranos impressed the company with its plans for in-store blood testing and technological promises surrounding its apparently state-of-the-art device that could deliver test results in 30 minutes. Company executives were so impressed that Walgreens poured $140 million in the venture — $40 million of which could be converted to equity.
