Kim Keon Hee became the first former first lady in South Korean history to be arrested and jailed when a court issued her detention warrant on August 12, 2025. Now, as her husband Yoon Suk Yeol sits in a separate detention facility following a 30-year prison sentence handed down on June 12, 2026, the country is witnessing an unprecedented political fall. The couple’s simultaneous incarceration marks a historic low for South Korean leadership, with both facing multiple criminal charges stemming from Yoon’s three years in office.
The Three Major Charges That Sent Kim Keon Hee to Jail
Kim Keon Hee was taken into custody after the Seoul Central District Court granted the request of Special Prosecutor Min Joong-ki’s team. The court issued the warrant citing concerns that she might destroy evidence, leading to her immediate transfer to the Seoul Southern Detention Center. She officially became inmate number 4398 when she appeared for her first trial on September 24, 2025.
The special counsel’s investigation focused on three main allegations against the former first lady:
- Stock Price Manipulation: Kim is accused of participating in a scheme to manipulate the stock price of Deutsch Motors, a BMW dealer in South Korea, between 2009 and 2012. Prosecutors say she conspired with a former head of the company and a close associate to make approximately 810 million won (around $561,000) in illegal profits.
- Election Meddling: Kim allegedly interfered with candidate nominations for the 2022 parliamentary by-elections and 2024 general elections. She is accused of receiving free opinion polls worth 270 million won from a power broker named Myung Tae-kyun in exchange for securing the nomination of a specific candidate for a parliamentary by-election.
- Bribe-Taking via Luxury Gifts: Prosecutors charged Kim with receiving luxury gifts worth 80 million won from the Unification Church through a shaman in 2022. In return, she allegedly promised business favors to the religious organization.
Before her arrest, Kim appeared for questioning at the special counsel’s office on August 6, 2025, becoming the first spouse of a former or sitting president to publicly appear as a suspect in a criminal investigation. She denied all allegations and apologized, calling herself “a nobody” who has caused concern to the people.
The Deutsch Motors Case: A Closer Look at the Stock Scheme
The stock manipulation case is particularly significant because it dates back to before Yoon even entered politics. Special prosecutors allege that Kim was actively involved in a scheme to artificially inflate the stock price of Deutsch Motors. The company’s former head worked alongside Kim and her associate to execute the manipulation, which generated illicit profits for those involved.
When she appeared for her first trial on September 24, 2025, Kim was asked to state her occupation. She replied briefly: “I am unemployed.” The court confirmed her identity and date of birth before proceeding with the case. She declined to request a jury trial, leaving the decision to the judge.
Yoon Suk Yeol’s 30-Year Sentence: The Drone Operation That Backfired
While Kim was arrested in August 2025 on corruption charges, her husband’s legal troubles took a different turn. On June 12, 2026, the Seoul Central District Court sentenced Yoon Suk Yeol to 30 years in prison for directing a drone infiltration operation into Pyongyang in October 2024.
The court found that Yoon ordered military drones to penetrate North Korean airspace with the specific goal of provoking Pyongyang. The plan was to heighten cross-border tensions and create a national security crisis that would give Yoon a reason to declare martial law on December 3, 2024.
The prosecution argued that Yoon’s drone operation was “a provocative military campaign” designed to create conditions for localized armed conflict or a national emergency. The court agreed, stating that Yoon’s actions “betrayed the people’s expectation that the president and the defense minister would use military force only for legitimate purposes.”
Several other officials were also sentenced in the same case:
- Kim Yong-hyun, former Defense Minister: 30 years
- Yeo In-hyung, former head of the Defense Counterintelligence Command: 15 years
- Kim Yong-dae, former chief of the Drone Operations Command: 3 years (suspended for 5 years)
The Martial Law Connection: How One Decision Led to Life in Prison
Before receiving the 30-year sentence for the drone operation, Yoon had already been convicted on a separate charge. In February 2026, a South Korean court sentenced him to life imprisonment for leading an insurrection through his December 3, 2024 martial law declaration.
The martial law declaration lasted only hours. Yoon sent troops to the National Assembly in an unsuccessful attempt to block lawmakers from voting to lift it. The move triggered months of political turmoil, disrupted foreign policy, and rattled the South Korean economy.
Yoon was impeached following the martial law debacle and formally removed from office in April 2026 after the Constitutional Court upheld the National Assembly’s impeachment decision. His conservative party lost a special election to choose his successor, and the new government appointed multiple special prosecutors to investigate both the martial law period and the corruption allegations surrounding Yoon and his wife.
Yoon’s legal team has appealed both the life sentence for insurrection and the 30-year sentence for the drone operation. They argue that the drone deployment was a legitimate military response to North Korea’s launches of trash-carrying balloons into South Korea in 2024, and that Yoon never ordered or approved the operation.
A Historic First: The Presidential Couple Behind Bars
The simultaneous jailing of a former president and his wife is unprecedented in South Korea’s constitutional history. Nearly every former South Korean president, or their family members and aides, has been mired in scandals near the end of their terms or after leaving office. The last two presidents elected from Yoon’s party — Park Geun-hye and Lee Myung-bak — were both sentenced to lengthy prison terms over corruption charges before being pardoned and released.
However, the Yoon-Kim case stands apart because both husband and wife are incarcerated at the same time. Yoon is held at the Seoul Detention Center in Uiwang, while Kim is held at the Seoul Southern Detention Center. Special prosecutors requested Kim be moved to a different facility to avoid the complications of holding both at the same location.
Yoon was initially arrested on insurrection charges on July 10, 2025. He became the first sitting president to be arrested and indicted. Within weeks, his wife joined him behind bars.
The Trial That Brought Kim Keon Hee to Court
Kim’s first criminal trial opened on September 24, 2025, at the Seoul Central District Court. She was escorted by guards and wore a dark suit with her hair tied back. The badge on her chest displayed her inmate number: 4398.
During the hearing, the court confirmed her identity and her occupation, to which she responded, “I am unemployed.” She declined to request a jury trial.
Legal experts noted that the case could see the former presidential couple summoned together over their alleged role in influencing parliamentary elections. Yoon, as president, had vetoed three special investigation bills passed by the opposition-controlled parliament that sought to probe the allegations against Kim. The last veto was issued in late November 2024 — just days before Yoon declared martial law.
The Broader Investigation: Dozens Indicted
The special counsel’s investigation went far beyond Kim Keon Hee. Over the course of the 180-day investigation, the team placed 20 people under custody and indicted a total of 66 people, including both Kim and her husband.
The investigation uncovered additional allegations that the former first lady received high-end jewelry and other gifts in exchange for promises of appointments to senior government and other jobs. The special prosecution team also faced controversies of its own, including allegations that the probe was biased and that the special prosecutor had engaged in illegal stock trading in the past.
Other high-profile figures indicted include former Prime Minister Han Duck-soo, who was charged with abetting Yoon’s imposition of martial law, falsifying and destroying official documents, and lying under oath. More than 60 people were separately indicted for rioting at a Seoul court that issued the warrant for Yoon’s first arrest in January 2025.

What the Sentences Mean for South Korea
The 30-year sentence for Yoon in the drone case, combined with his life sentence for insurrection, effectively ensures that the former president will spend the rest of his life in prison unless pardoned.
Yoon has the right to appeal the latest ruling by the Seoul Central District Court. His legal team has already filed an appeal and argues that the verdict was “politically motivated.”
The case has drawn international attention, with news outlets across the world covering the downfall of a president who, just two years ago, was leading one of Asia’s most influential democracies.
