Abu Mousa was a suspected terrorist during the events of Trinity.
Before Trinity Edit
Mousa was a marketing coordinator at an advertising agency on Wilshire Boulevard. He had no record that suggested he had any links to terrorists until CTU agent Nina Myers found plastic explosives in Mousa's apartment.
Nina Myers and Jack Bauer went to see Mousa in the "Twin Towers" Detention Facility. Jack asked him where the explosives came from, and Mousa said that a friend had asked him to look after them, and he simply thought it was modelling clay. Jack became angered and started to physically interrogate Mousa, but Ryan Chappelle entered and stopped him before he could continue.
