Kwon Ri-sae, 23, died today morning at a hospital in Suwon, just south of Seoul. She had been unconscious after undergoing hours of emergency brain surgery following Wednesday's accident, according to agency Polaris Entertainment spokeswoman Kim Eun-kyung.
Fellow band member Go Eun-bi died shortly after a van carrying the group crashed into a guard rail on a rain-drenched highway near Seoul.
Police suspect that the van driver may have been speeding on the wet road to meet a tight schedule. The National Forensic Service is currently investigating the accident.
Another member of the five-member group fractured her jaw and two others suffered minor injuries. Ladies' Code debuted last year.
