Randy Murdoch was an intelligence agent and forensics expert brought in to CTU Los Angeles from CTU San Diego to aid with the search for the nuclear bomb.
Murdoch analyzed a burnt fragment that was found on Syed Ali's clothing after a decoy was burned to death to distract CTU agents from finding Ali. Through a paper fiber analysis, Murdoch was able to find, at first, the number N34, and later, N34G5, which was cross referenced to be a tail number to a plane at Norton Airfield. This was the plane which Omar was supposed to pilot with the bomb inside.
