Actress Jeon Mi-seon, 48, was found dead in a hotel room in Jeonju, North Jeolla Province, at around 11:45 a.m. Saturday, according to police officials.
Local police were dispatched upon the call of Jeon's manager that the actress had gone missing.
The actress was scheduled for a two-day stay at the hotel for a provincial tour of a theatrical play.
Jeon, who was already deceased at the time of discovery, is likely to have taken her own life, officials said.
