Alex Jameson was a Vice President of Farrow-Marshall Aeronautics, a company with links to the Trust. Unbeknownst to anyone, he was implanted with a Goa'uld symbiote, and worked to further the Goa'uld-controlled organization's aims. His wife, Sheila Jameson, unaware of his possession, believed that his newfound secrecy was due to him having an affair, hiring a private investigator to tail him. Eventually, the Trust was taken over by Ba'al. This was discovered by Gerak, who sent his Jaffa to Earth to capture the System Lord. Unaware of this, Jameson had left his home ostensibly for a meeting, but in reality to meet Trust agents. The Jaffa attacked the meeting and Jameson was captured and taken to Dakara, where Gerak had him extensively tortured for information on the whereabouts of Ba'al. He was able to resist for a length of time, but eventually, after more torture, he revealed the locations of Ba'al and his hideouts. His final fate was not shown but it was likely he was either killed by Gerak's Jaffa or died of his injuries sustained due to the torture he received at the hands of Gerak and his Jaffa.
