Theranos CEO wooed investors while lab director saw trouble

Theranos Founder Fraud Trial

SAN JOSE, Calif. (AP) — Fallen Silicon Valley star Elizabeth Holmes convinced media mogul Rupert Murdoch and other billionaires to invest in her biotechnology startup despite warnings its unconventional blood tests were dangerously unreliable, according to evidence presented Tuesday during her criminal trial.

The revelations emerged during the eighth day of a high-profile trial revolving around allegations Holmes duped investors, customers and unwitting patients as CEO of Theranos, a company she founded after dropping out of college in 2003 when she was 19.

Holmes briefly became a Silicon Valley sensation while peddling the premise she had invented a breakthrough technology scan for an array of health problems using just a few drops of blood taken with a finger prick.

But Adam Rosendorff, a medical doctor who oversaw Theranos' clinical laboratory from September 2013 through November 2014, drew a darker picture Tuesday while testifying as witness for the federal government prosecutors trying to convince a jury to convict Holmes on 12 counts of fraud.
