Gabriel Bell (April 24, 1987 – September 3, 2024) was a male Human who was a resident of San Francisco's Sanctuary District A in the 2020s. During violent riots that convulsed the sanctuary district (which later became known as the Bell Riots), Bell attempted to resolve the situation peacefully, becoming a national hero and a martyr for social change in the United States of America.
When residents of Sanctuary District stormed a processing center and took several government employees hostage, Bell protected them from the more extreme and violent residents. When the San Francisco Police Department received inaccurate intelligence that the hostages had been killed, they stormed the processing center, killing several of the Sanctuary District residents. Bell himself was also killed, protecting the government hostages. (DS9 episodes: "Past Tense, Part I", "Past Tense, Part II")
After Benjamin Sisko, Julian Bashir and Jadzia Dax were transported back in time to 2024 from 2371, Sisko and Bashir found themselves forced into the Sanctuary District on the eve of the Bell Riots. Gabriel Bell was killed protecting Sisko and Bashir, forcing Sisko to assume Bell's identity and guide the Bell Riots to the conclusion that Sisko knew had happened. (DS9 episodes: "Past Tense, Part I", "Past Tense, Part II")
The Federation Department of Temporal Investigations investigated the replacement of Bell's image with Sisko's, deciding it was only a continuity glitch that posed no real danger. (STO novel: The Needs of the Many)
