Saw this pop up on a Korea Herald app I still have from a trip to Busan years back. Didn't know the man, only the name attached to Han Dong-hoon, but that first class at the Judicial Research and Training Institute thing stuck with me, that's no small feat. 81 is a full life.

Jin Hyung-gu (진형구, 秦炯九) was a South Korean prosecutor who rose to some of the most senior posts in the country's prosecution service before a single remark to reporters in June 1999 placed him at the centre of the Korea Minting and Security Printing Corporation strike-inducement affair, the case that led to South Korea's first ever independent special counsel. He died on 15 November 2026, aged 81. In his last years he was also widely identified as the father-in-law of Han Dong-hoon, the former justice minister and National Assembly member.
Jin was born on 24 September 1945 and came from Gwangju in Gyeonggi Province, according to Yonhap News Agency. He attended Gyeongbok Middle School and Gyeongbok High School in Seoul, then studied electrical engineering at Seoul National University, graduating in 1967. That science background made him unusual among Korean lawyers of his generation, and Yonhap noted that he drew attention from the start of his career as an engineer turned jurist. He passed the 11th national bar examination and completed the first class of the Judicial Research and Training Institute. He later earned a master's degree in criminal law from Seoul National University's graduate school in 1975 and a master's in comparative law from Southern Methodist University in the United States in 1980.
As a prosecutor Jin built a reputation as a planning and policy specialist. He served as a research officer at the Supreme Prosecutors' Office, headed its computer management unit, and led the human rights and legal affairs divisions at the Ministry of Justice. Through the late 1980s and early 1990s he held a run of senior Seoul posts: head of the second criminal division at the Seoul Western District office, prosecutor at the Seoul High Prosecutors' Office, head of general affairs and then investigation at the Seoul District Prosecutors' Office, second deputy chief prosecutor in Seoul, and chief of the Seoul Western District branch. Promoted to chief prosecutor rank in 1995, he headed the Supreme Prosecutors' Office's trial and litigation department and, from 1997, its inspection department. In March 1998, under the Kim Dae-jung government, he became head of the Supreme Prosecutors' Office's Public Security Department, even though he had no earlier public security experience.
In 1999 he was promoted to chief of the Daejeon High Prosecutors' Office. In June that year, at a lunch with reporters, he said in effect that the prosecution had induced the 1998 strike at the state-run Korea Minting and Security Printing Corporation. The remark caused a national uproar. He lost his post, and Justice Minister Kim Tae-jeong was also dismissed over the affair. Jin was arrested in July 1999 on charges including abuse of authority and was released on bail in August. Testifying at a National Assembly hearing that month, he denied pressuring the corporation's president, Kang Hee-bok, and said he had made a careless slip while drunk. The controversy led the National Assembly to pass the country's first special counsel law, and special counsel Kang Won-il questioned him in November 1999. The special counsel's team overturned the earlier prosecution finding that Jin had acted alone and indicted Kang Hee-bok.
The courts later acquitted Jin of abuse of authority and obstruction of business. In 2001 the Seoul District Court found him guilty only of breaching the labour union law's ban on outside intervention in labour disputes and gave him a suspended sentence. The appeal court reduced the sentence to eight months, suspended for one year, and the Supreme Court upheld the ruling on 15 April 2005.
After leaving the prosecution Jin worked as a lawyer and turned to publishing. In December 2002 he became publisher of China Life, a monthly magazine about China, saying he wanted to repay society as a journalist with the experience he had built as a lawyer. He also chaired a committee promoting memorial projects for the independence activist and statesman Shin Ik-hee. From 2013 he was active in Lawyers for Human Rights and Unification of Korea.
Jin was married to Choi Young-ok. His children include his son Jin Dong-gyun, a former prosecutor, and his daughters Jin Min-jung and Jin Eun-jung, a lawyer. Jin Eun-jung is married to Han Dong-hoon. After Han entered politics, Jin's 1999 case and other episodes from his past were revisited in Korean media, including a 2022 Newstapa report on allegations linked to an old stock manipulation case in which he was not charged.
He died on 15 November 2026. His cause of death has not been made public. His funeral was held at the Seoul St. Mary's Hospital funeral hall, with the funeral procession set for 18 November 2026.
