Gabriel Schector

An arms-dealer and smuggler that is involved in the thefts orchastrated by Tony Almeida, leading up to the events of Day 7. According to Jack Bauer, both he and Almeida captured Schecter in the past and, instead of turning him in, allowed his operations to continue - so he could work as an informant.

Day 7
At some point after the events of Day 5, the thought-dead Tony Almeida recruits Schecter to finance and use his connections in the underworld to aid in several, low-profile heists that are aimed at collecting weapons, hardware and information.

But a hunch and a serial-number lead both Jack Bauer and Brian Gedge to connect Schecter's criminal activities to the heists and Tony Almeida's organization. As an F.B.I. raid is mounted, Bauer argues that a man like Schecter will tie things up with his attorney's and use red-tape to keep himself out of the hands of the law. It is because of this that agent Renee Walker brings along Bauer for the questioning; playing off the loose-canon reputation of the rogue CTU operative.

Both confront him at his apartment. Terrified by the presence of Bauer, he agrees to let both of them in on the condition that Bauer stay far away from him. In the room, he is arrogant and taunts both with the knowledge he has. But he hides behind his bodyguard, Ari. Things escalate when his bodyguard tries to forcefully throw out Agent Walker and Bauer. Before his very eyes, he watches Agent Walker disarm and incapacitate the much larger Ari. Then, she gives Bauer permission to torture him for information.

As an ink-pen is hovered centimeters over his pupil; Schecter agrees to confess everything. However, Alan Tanner shoots him three times in the chest via sniper-rifle before he can. Both Schecter and Ari are killed in the onslaught, effectively ending the lead.
