Austin police are conducting an urgent search for a girl missing since 2017 after the disturbing discovery of her 7-year-old sister, who was locked in a closet and malnourished. The sister was reportedly kept in the cramped space for weeks, surviving on minimal food. Following this revelation, authorities have arrested their mother on charges related to the severe mistreatment of her children. The ongoing investigation aims to locate Ava Gonzales, the missing girl last seen several years ago, as police express concern over her well-being.
