Maquin, also a Guatemala national, had begun having seizures roughly eight hours after being taken into custody with her father. Emergency responders measured her temperature at over 105 degrees, according to the Washington Post. She died within 24 hours of arriving at the hospital.
The girl's family and CBP dispute the details of her death. CBP said that she had reportedly not consumed food or water in several days, but denies allegations from her family that it did not provide food or water during the first eight hours they were detained.
The family and CBP also dispute when the girl was showing signs of illness. Rep.
