Condolences to the friends and family of Byun Hee-soo:

Byun hee-soo, a 23-year-old transgender former soldier forced to discharge from the Army last year, was found dead at her home, police said Wednesday.

The Army made the discharge decision in January last year after judging that Byun’s loss of male genitals belongs to the Level 3 physical disability under the military laws.
