Diana Mendez was Adrian Conrad's personal assistant. She transferred $3 million to Harold Maybourne's Cayman Islands account for a Goa'uld symbiote. She was overseeing the implanting of the Goa'uld symbiote in her boss's body in attempt to cure the terminal disease he was suffering from. Adrian Conrad's Goa'uld later tricked her into releasing him and murdered her in the process. Although it is not shown, it's implied that she could have died when the Goa'uld snapped Diana's neck, killing her. (SG1: "Desperate Measures")
