Jim was guarding one of the main entrances to the CTU New York building. After the EMP detonation, he received instructions from Brian Hastings to verify that every person that wanted to go out was authorized by him.
At around 7:00am, Dana Walsh went to the exit when Jim stopped her and told her about Hastings' instructions. She attempted to convince him telling him that she only wanted to go to her car to look for her migraine medicine. Jim offered to send a guard to the car for her, but she told him it was okay and that she would clear herself with Hastings.
Some time later, Dana went by the exit again and gave Jim her card telling her that Hastings had authorized her. When Jim checked the card in his laptop, a message came up instructing guards and agents to arrest Dana on sight. As he pulled out his gun and told her to hold, Dana drew out a gun herself and shot Jim and a nearby guard, killing them.
