This article reports on a lawsuit and family’s account that a 3‑year‑old immigrant girl was allegedly sexually abused while in U.S. federal custody after she was separated from her mother at the U.S.–Mexico border and placed in a foster home. Her father, a legal permanent resident, spent five months trying to reunite with her before learning of the abuse, which was disclosed during a forensic examination following delays in the reunification process. The story also discusses how changes to immigration custody and release policies have lengthened the time children spend in government care and sparked legal challenges, and it describes the emotional and psychological impact on the child and the family’s ongoing efforts to hold officials accountable.
