While he was on duty, he stumbled across Rookie One and Ru Murleen, both of whom were members of the Rebel Alliance disguised as Stormtroopers, in a restricted area. He quickly realized the two were intruders due to their lack of security clearance and raised the alarm when Rockie One seals the door beside them.
During the search for the two Rebels, he inspected a Stormtrooper guard about to doze off in the hangar. While the officer scolded the Stormtrooper, behind their backs Rookie One and Ru Murleen exited the sewers of the Terror and gained access to the hangar.
The officer and the Stormtrooper barely had the time to dodge the stolen TIE Phantom that flew right over them on its way to the exit.
The officer was most probably killed in the explosion of the Terror, after the Rebels destroyed the ship's internal systems.
