Nathan Hansen

Nathan Hansen was the son of Air Force pilot John Hansen and Dorrie Hansen. He also had a sister, Jenn.

Day 4
During Day 4, Jenn and Nathan were with their mother when armed men entered their home. Dorrie phoned John as directed by the men, and informed him that they would be killed if he didn't follow the orders of Nicole, his lover. Even though John cooperated, John was killed by Mitch Anderson, and Nathan, his mother, and his sister were killed by Habib Marwan's men. Their bodies were hidden by their murderers.

A relative reported that they were missing after he visited the house and found no one home. The report was not examined in time by CTU analyst Edgar Stiles, who handed off part of his work to a subordinate analyst named Meg. Marwan and Rafique successfully distracted CTU from taking note of the importance of the report by staging a distraction: a hostage exchange of Jack Bauer for Behrooz Araz.
