Hundley Yeoksam serves within the Criminal Police Organization. During the events stemming from the Haunzen flight incident, he was a passenger aboard Flight 356. Seated on the starboard side, he witnessed the hijacking attempt by individuals claiming Mafty affiliation. Following the forced landing in Davao, Philippines, Yeoksam approached Hathaway Noa in the airport lobby. He identified Hathaway as the son of Earth Federation Forces officer Bright Noa and questioned him about participation in mobile suit combat during Char's Rebellion, citing Hathaway's prior admission of unauthorized deployment.

Yeoksam coordinated with Bureau of Investigation agents to arrange an interview with Hathaway. He also facilitated logistical support, securing hotel accommodations for Professor Amada Munson. Hathaway was training as a botanical observer under Professor Munson. Yeoksam invoked Professor Munson's philosophical principle of "no revival without purification," drawing a parallel between this ideology and the objectives of his own Criminal Police Organization.
