There's also a lot of "WHY AREN'T YOU FOCUSING ON THE MOTHER?" whataboutism in the comments, which I find appalling. The article was about something else, and who knows what her circumstances were.
You are right, the article is about:
> She said at the point Homeland Security ended her abuse she had been "praying actively for it to end".
You can provide your plausible suggestions as to what the family relationship looked like that the girl could neither ask her own mother for help nor was her father there for her.
Most crimes like this are, sadly, committed by someone who has some connection to the family. It’s standard to investigate connections first. That’s not “appalling” to suggest, it’s just a sad reality of these crimes.
They should be focusing on everyone connected to the family if known. It would be negligent not to.
The confusion came from the way the article was written. They didn’t know the identity until afterward.
