Theranos founder Elizabeth Holmes’s bid for retrial denied by federal judge

Holmes faces up to 20 years in prison after being convicted on 12 counts of fraud and conspiracy

A federal judge denied the Theranos founder Elizabeth Holmes's bid for a retrial on investor fraud charges after finding that an attempt by a remorseful prosecution witness to contact her didn't introduce material new evidence or establish government misconduct - and it wasn't enough to award her another trial.

The ruling issued late Monday by US district judge Edward Davila is a setback for Holmes, who faces up to 20 years in prison at sentencing on 18 November. Holmes was convicted on 12 counts of fraud and conspiracy in January and had previously been denied a request for an acquittal.
