Could Citizenship Affect the Next Steps in the Cornell Case Involving a South Korean Defendant?

SEOUL — Questions are growing over whether the nationality of a South Korean man identified by surname as Lee could affect the next stage of the case linked to an alleged gang rape at Cornell University.

Lee is among seven current or former Cornell students named in a civil suit alleging that a former student was sexually assaulted at the Chi Phi fraternity house in October 2024, according to earlier reports. The seven were not charged in the criminal investigation at the time after prosecutors determined the evidence gathered in the initial police probe did not support charges.

The situation changed this week when Tompkins County District Attorney Matthew Van Houten said his office had reopened the criminal investigation and would submit it to a grand jury to determine whether criminal charges should be brought, local reports said.

In South Korea, attention has centered on Lee because his nationality and background remain unclear. Social media posts have circulated images and videos allegedly showing him in the South Korean military. Some users have suggested he may be a South Korean citizen, a dual U.S.-South Korean citizen, or the child of a former South Korean prime minister. Neither Lee nor his lawyers have confirmed or denied those claims.

Would citizenship change the legal process?

A Seoul-based lawyer with the surname Kim, who joined the New York State Bar in 2024, said Lee’s citizenship should not limit New York authorities’ ability to investigate or prosecute him if the case justifies it.

In New York, criminal jurisdiction is usually tied to the place of the alleged conduct and its nature, not the accused person’s passport.

Kim said that if Lee is in the United States, his status as a U.S. citizen, South Korean citizen or dual citizen would not prevent New York authorities from investigating or prosecuting the alleged incident at Cornell.

Lee is listed as an enrolled student in Cornell’s university directory, and reports have suggested he returned to campus and resumed classes.

The case could become more complicated if Lee is now in South Korea and does not agree to travel to the United States for the investigation. In that scenario, U.S. authorities would generally need to seek extradition through the 1998 extradition treaty between the United States and South Korea.

Extradition is a formal process in which one country asks another to surrender a person for prosecution, trial or punishment. Kim said Article 3 of the treaty means neither country is required to extradite its own citizens, though each may do so at its discretion.

He added that a refusal to surrender Lee because he is a South Korean citizen would not automatically end the matter. If the United States requests it, South Korea would have to refer the case to its own authorities so they can decide whether to prosecute him domestically.
