The case of a civil servant in the West Sea ‘flighted to North Korea’ became a political issue in the Yun Seok-yeol administration, and the military communications interception and SI information disclosure was also heard.
Rep. Kim Byung-joo (former deputy commander of the Combined Forces Command) said on the 20th, "Under the judgment of the Yun Seok-yeol government and with the cooperation of the United States, the SI (Special Intelligence) information at the time can be disclosed." As much as there is, I hope that you will be aware that harm will follow to the security of the Republic of Korea.”
Rep. Kim and other members of the Democratic Party of the National Defense Commission changed the name to ‘the West Sea civil servant murder case’ on the same day and announced, “If you desperately want to disclose the minutes of the meeting that were not closed on September 24, we will cooperate with the reading and disclosure of the minutes in accordance with the National Assembly Act.”
Former Defense Minister Seo Wook said at the National Assembly Defense Committee on September 24, 2020, "The conclusions made so far are judged to have defected to North Korea."
Ahn Young-ho, then head of the Joint Chiefs of Staff Operations Headquarters, said, "The North Korean personnel seem to have listened to statements from North Korea while keeping a certain distance from the ship and checking the circumstances of the disappearance of the missing person while wearing a gas mask."
Regarding the floating object, former Minister Seo said, "As a result of synthesizing information, it is enough that one person can climb it."
At that time, the intelligence depended on the RC-135V/W rivet joint of electronic communication information among the U.S. communications interception reconnaissance aircraft or the RC-12X guard rail of the wiretap reconnaissance aircraft. In the case of 'Baekdu', an intelligence collector, the U.S. has the upper hand in the West Sea area near the ceasefire line, and the South Korean military has introduced an Israeli-made Heron reconnaissance aircraft, but communication interception has shown dependence on the United States.
In the video recording of the floating object, it is known that the US military intelligence satellite 'Keyhole' identified an object 10 cm above the ground in North Korea with an infrared detector.
Regarding the floating object, former Minister Seo said at the National Assembly, "The length is not as tall as a person's.
An editorial on the 20th of the Chosun Ilbo asserts that “the Democratic Party had a basis for defecting to North Korea.” Then you need to disclose the evidence. They also make excuses that “the intelligence system shouldn’t be exposed.” If that is the case, then the public prosecutor or auditor can read the records and draw a conclusion.>
The Hankyoreh editorial said, “The ruling party will be well aware of the reality that we cannot disclose information about North Korea hastily.”
On the 20th, Lee Rae-jin, the older brother of Lee Dae-jun (47 years old at the time of his death), who was involved in the case, announced on the 20th that he would sue three people, including Seo Hoon, former security chief Kim Jong-ho, and former Blue House civil affairs chief, Lee Kwang-cheol, former civil affairs secretary for obstructing the execution of public affairs.
