Gerard A. Tobin had been a security guard working the graveyard shift at Immunitech Research in Steveston, Oregon. He shadowed SG-1 during their investigation in the town and cooperated by reporting that Dr. Richard Flemming had come to him warning of danger and seeking help just before his mysterious disappearance. Tobin believed that Flemming had been murdered and that Flemming's warning had saved his own life from the arson fire at Immunitech.
