Mentioned in "Nightwalkers"
Peter Stofer was a geneticist who worked for Immunitech Research on Goa'uld cloning. He disappeared in 2002 shortly after his partner Dr. Richard Flemming fell under the control of an immature Goa'uld. His fate is unknown, though he was presumably killed by the cloned Goa'uld. (SG1: "Nightwalkers")
