Vincent Cardiff

Tony Almeida met up with Jack Bauer at 5:56pm near the United States Capitol to alert him of an impending attack. Hours later, when Jack was being debriefed by FBI Agent Mizelli, "Vincent Cardiff" was revealed to be the name of Tony's source. Jack was asked whether he personally spoke to the suspect, and Jack said the source did not survive Tony Almeida's interrogation.

MIzelli began investigating records and discovered that Vincent Cardiff was arrested just an hour ago by Customs while trying to cross the border into Canada. Jack asked if there was any signs of physical abuse on Cardiff, to which Mizelli replied "nothing was indicated on the report". Realizing that he had been lied to, Jack confronted Tony and pulled a gun on him demanding an explanation. Tony admitted he lied about the death as part of the deal he made with Cardiff which would allow him to disappear in return for the information. Tony said the intel was good and that without it Jack wouldn't have been able to save the President at the White House.
