A woman in her 30s who went missing on Jeju Island was found dead, but the cause of death could not be determined due to body decomposition. Police are considering the possibility of foul play and are reviewing approximately 310,000 missing person cases that have been closed in the past three years in light of this incident. They also plan to take measures to prevent a recurrence of missing person cases, such as improving the risk assessment method for missing person reports and strengthening nighttime staff.
