Larry Moss was the Special Agent in Charge of the FBI's Washington Field Office during Day 7. He was reluctant but accepted Renee Walker's proposal to enlist Jack Bauer to help bring down his former ally Tony Almeida who was behind some technology thefts that occurred prior to Day 7. Over the course of the day his attitude towards Bauer changed after he recognized that he judged Jack for the wrong reasons. Almeida gained the trust of the FBI before stealing a lethal bioweapon and killing Larry by suffocating him.
