Samir Mehran was a conspirator working with the Kamistan splinter cell leader Farhad Hassan during Day 8. In the events of Day 8, he led most of the field operations of the Kamistani splinter cell in America. With a businessman supporting him and his own crew of Revolutionary Guard recruits, he discarded Farhad's original scheme for the rods and created a radiological bomb with which to threaten New York City. He was shot by Jack Bauer mere moments after he had slit President Omar Hassan's throat on a video feed to the Internet. Though he survived the gunshot wounds, he was killed approximately 45 minutes later by cardiac arrest induced at Hassan's murder scene by Pavel Tokarev, who was disguised as an EMT.
