Robert S. Armstrong, 49, was sentenced to 65 months in prison for mailing thousands of fraudulent invoices to hospitals, clinics and doctors’ offices throughout the United States. Operating under the name of Pinnacle Medical Supplies, Armstrong prepared and caused to be prepared fraudulent invoices billing hospitals, clinics and doctors’ offices across the United States for medical supplies such as diabetic test strips, EpiPens® and sanitizing wipes that the medical providers never ordered or received. In addition to billing for medical supplies never ordered or received, the invoices included fraudulent shipping information and a fraudulent address. Armstrong then contracted with a legitimate bulk mailing company to mail more than 10,000 invoices to medical providers across the United States. Each invoice included a payment envelope preaddressed to Pinnacle Medical Supply at mailboxes Armstrong had set up with commercial mail receiving agents in Florida and Texas. In response to the phony invoices, at least 943 medical providers sent $214,495 to Pinnacle Medical Supply. Armstrong deposited many of the checks from the victim medical providers into a bank account he opened in the name of Pinnacle Medical Supply. In addition to the prison term, Judge Hillman sentenced Armstrong to an additional three years of supervised release and ordered him to pay full restitution.
