It appears to be a historical investigation as both companies said they received subpoenas in 2007 and 2009. A jury in San Francisco last week convicted three defendants "of operating illegal pharmacies that used FedEx and UPS to deliver drugs without proper prescriptions." In all, there have been ten such convictions in San Francisco this year (including guilty pleas prior to indictment and from those who decided to cooperate after indictment, and a few who went to trial earlier in the case.)

Here's an article on the three men convicted last week in San Francisco. The trial lasted six weeks.

A federal jury in San Francisco convicted Pekin businessman Daniel Johnson and two other men Thursday of operating a $26 million online pharmacy to sell millions of prescription drugs over the Internet outside of legal and medical regulations.

... Federal prosecutors accused Johnson of operating the computer elements for a business in which the defendants filled orders for 4.4 million pills, 94 percent of them controlled substances. Most of the drugs were sold as tranquilizers, diet pills and impotency drugs

....Prosecutors told the jury the trio sold millions of pills to people across the country without face-to-face consultation by Carozza to confirm their need for medical prescriptions.
