Not sure how this is in any way an America specific thing.
The abortion was at 28 weeks, fetuses are viable outside the womb at 24 weeks, and Nebraska allows abortions until 20 weeks. They waited two whole months past the point they could have taken care of this with no fuss, one month past the point of viability.
They didn't do this through a doctor or any safe/proper way. The pregnant woman took medicine to kill the fetus, then delivered it as a stillbirth. Her and her mother then burned the stillborn and buried it on a farm.
The mother and daughter told police they discussed it in their facebook dms, police made a formal legal request for the dms to facebook and facebook complied. They didn't follow the golden rule of "don't talk to police". On top of that, the court documents indicate that the dms were part of a bunch of evidence that made the case, not the single piece of evidence that convicted them.
Honestly asking, is there something I'm missing here that would have made this turn out differently in another country? America isn't as great as its own patriotism claims, but I see this take very often in situations that don't seem to have much at all to do with it happening in America.
