Their whole story is falling apart: https://www.chicksonright.com/youngconservatives/2018/12/14/the-viral-story-of-7-year-old-migrant-girl-who-died-in-border-patrols-custody-begins-to-unravel/
Interesting information there.
It doesn’t sound as if the father was making an effort to make Border Patrol aware that his daughter was ill, and I don’t think that there was any way he could have not known that she was ill.
If I read the article correctly, it was 2 hours after the group surrendered to Border Patrol before she was seen by EMS. Not the Border Patrol’s fault, if they were not aware that she was sick. That means she died 6 hours after her illness was discovered. IMO, that means she was pretty close to death when anyone in Border Patrol became aware that she was sick. I have no doubt that everything possible was done to save her and she was too far gone by then. IMO, not the fault of anyone except those she was traveling with, including the father.
Legal or illegal, medical personnel are going to fight and fight hard to save a child. I don’t think anyone wants to see any of these people die. Wanting them to go back to where they came from isn’t wishing for their deaths.
