Go Eun-b of the five-member girl band Ladies' Code died in a car accident in the early hours of Wednesday. She was 23.
Go was killed after a van carrying the band and managers slipped on a rain-slick road and hit the hard shoulder on a highway near the Singal intersection toward Seoul.
She was taken to a nearby hospital but pronounced dead on arrival.
Two other members of the band were severely injured and are being treated along with other passengers.
The group were on their way back to Seoul after a performance in Daegu.
