Agent Stoller was part of the large FBI search team that was dispatched by Renee Walker to find the fugitive Robert Galvez. He was discovered and murdered by Galvez, however, not far from the building at 1297 Rincon. Galvez then used Stoller's radio and impersonated the agent, disrupting the radio to mask his voice. Jack Bauer located Stoller's radio transponder, and discovered that Stoller was not in the building at 1297 Rincon, but was too late. Posing as Stoller, Galvez lured about thirty agents into an ambush. Although Jack Bauer spotted the ambush when he had FBI agent Lange locate Stoller's signal, it was too late: Galvez detonated his bombs, injuring and killing many of them using C4 charges.
