The first witness the prosecution called Wednesday morning was a medical sales representative who testified Dr. Conrad Murray's credit card was declined.

Sally Hirschberg works for Seacoast Medical Supply company and told the court her company did not fulfill an order from Dr. Murray for an infusion I.V. set because of the card being rejected.

Hirschberg said, "The account, I believe, had a credit card declined and so the paper work was pulled from the warehouse prior to being ordered or shipped." 

Prosecutor Davide Walgren followed up with, "So it was not shipped?"

Hirschberg replied, "No."

Prosecutor David Walgren entered into evidence invoices from Seacoast that established Dr. Murray's history with the company dating back to 2006.

One of the records showed Dr. Murray attempted to have I.V. equipment sent to his girlfriend Nicole Alvarez's Santa Monica, California apartment. Hirschberg said that the private residence raised read flags at her company and they refused to send the equipment to that address.
