Jeff Benson was the prison guard to druglord inmate Ramon Salazar. Benson's son was secretly taken hostage by Salazar's allies and was promised his freedom only if Benson murdered the attorney Luis Annicon. On Day 3, Benson reluctantly lured in Annicon, saying Salazar was ready to talk. When Annicon went into the cell, Benson killed Annicon with his club and was told by Salazar that his son would be returned. CTU Director Tony Almeida later mentioned that Benson had been arrested.
