She was the younger of two sisters left alone at home when the fire broke out around 4:15 a.m. in a fourth-floor apartment in Gaegeum-dong, Busan, while their parents were away working early-morning jobs.

The fire was extinguished in about 20 minutes, but the 10-year-old sister died at the scene. The younger sister was placed in intensive care and remained there until she was declared brain-dead on Tuesday. Her family then decided to donate her organs.

Authorities are continuing to investigate the cause of the fire.

Fire authorities, police, and other related agencies are conducting a joint investigation at an aparment unit where a fire broke out early Monday. (Yonhap)
