Charlie Parkhurst was a survivor in the Sonaran Desert and a good friend of Isham Seely. The two of them held out in a pharmacy in Sienna for a time, until she disappeared. Isham had no idea as to what happened to her, and thought she was dead, until it was discovered that she'd been locked in a cell outside in the F.E.M.A. compound. The Survivalists managed to break in and rescue her, much to her gratification. She and Isham were reunited happily, until the awful revelation came. She had been experimented on by Clara Allison and F.E.M.A. scientists, and she was discovered to be a Living Infected. She violently attacked Isham, and she was put down, leaving Isham dismayed.
