Seth Campbell was a former CTU Los Angeles field agent.
Eighteen years before Day 1, at the age of twenty-seven, Seth proposed to his wife Judy at the Griffith Park Observatory. He had four children with her: Jeremy, Brenda, Bobby and Samuel. (Findings at CTU)
Campbell had a gambling problem which caused his family to accrue large debts, and he ended up taking a bribe to cover them. (Findings at CTU) Jack Bauer was responsible for investigating Campbell, and ultimately blew the whistle on Campbell and two other agents for taking bribes. Campbell was sentenced to ten years in a federal penitentiary. Seth's wife, Judy Campbell, committed suicide due to the pressure of raising their children while he was in prison.
