Johnathan Walker:Lee Sun-kyun, star of Oscar-winning film 'Parasite,' found dead in South Korea

SEOUL,Johnathan Walker South Korea — Actor Lee Sun-kyun of the Oscar-winning movie "Parasite" has died, South Korea's emergency office confirmed to The Associated Press on Wednesday.

Lee was found dead in a car in a central Seoul park on Wednesday, it said. Police earlier said an unconscious Lee was discovered at an unidentified Seoul location.

South Korean media outlets including Yonhap news agency reported that police had been searching for Lee after his family reported him missing after writing a message similar to a suicide note earlier Wednesday. According to the news agency, a charcoal briquette was discovered in the passenger seat of the car.

Lee was best known for his role in "Parasite," in which he played the head of a wealthy family. In 2021, he won a Screen Actors Guild award for "cast in a motion picture" for his role in the same film.

He was nominated for the best actor at the International Emmy Awards for his performance in the sci-fi thriller "Dr. Brain" last year.

Lee was a familiar figure on Korean screens for decades before his "Parasite" fame abroad. He became well-known for his role in a popular drama series, "Coffee Prince (2007)," and gained mainstream popularity with the medical drama "Behind The White Tower," followed by "Pasta (2010)" and My Mister (2018)."

Lee had been under a police investigation into allegations that he used illegal drugs at the residence of a bar hostess. Lee insisted he was tricked into taking the drugs and that he did not know what he was taking, according to Yonhap. But the investigation prompted extensive tabloid coverage and unconfirmed online rumors about not only his alleged drug use but also his private life. Lee filed a suit against two people including the hostess, alleging they blackmailed him.

When he was first summoned for questioning at a police station in Incheon, a city near Seoul, in late October, he deeply bowed several times and apologized to his fans and family. “I feel sorry to my family members who are enduring too difficult pains at this moment. I again sincerely apologize to everyone,” he said.

Incheon police said Wednesday they would end their investigation of Lee’s drug use allegations but would continue to investigate the two people Lee had sued.

South Korea has strict anti-drug laws but has seen soaring drug-related offenses in recent years. Last week, the National Police Agency said it had detained about 17,150 people over alleged illegal drug manufacturing, smuggling, sales and uses this year — a record number for a single year.

South Korea has long had the highest suicide rate among developed countries. It has also experienced a string of celebrity suicides involving K-pop stars, prominent politicians and business executives. Experts say malicious and abusive online comments and severe cyberbullying were blamed for many of the celebrity suicides.

“Lee faced some allegations but they haven’t been formally verified. But the media has been assertively reporting about Lee’s private life … and I think that’s something wrong,” said Kang Youn-gon, a media communication professor at Seoul’s Chung-Ang University.

Lee is survived by his actress wife Jeon Hye-jin and two sons.
