I read this on Korean article, and apparently the women was returning from the last trip with her boyfriend before breaking up. She was found dead about 10 minutes before touchdown.

Meanwhile, on 5/29 an 39-year-old American women gave birth (in a galley) to her child about 10 hrs. into the flight bound for JFK (KE085). Both mother and child are safe, thanks to the assistance of doctor and crews onboard.
