If my surmise that the child was stillborn is correct, then this sounds like a case of poor support for a pregnant woman. It's terrible when they don't get support. It's one of the hardest times in anyone's life, having a baby; a happy time, but a hard time. When it goes bad, it's life-shattering, losing a baby. And she went through it alone. No prenatal care, gave birth outside a hospital--and not the cozy way, with a midwife and family and a hospital on speed-dial. It's honestly just sad. I feel like she just couldn't bring herself to call paramedics and say, "I had a baby, but she's dead."
Maybe I'm more charitable than I should be--the first 24 hours are the most dangerous time of anyone's life, after all--but... I don't know, this just doesn't seem like the sort of situation that calls for anger. If I'm wrong and she's guilty of some kind of manslaughter or even murder, then fine; but man, if not, I hope they don't throw the book at her. She did her best to give that child some sort of a dignified burial, by leaving her in that baby hatch. It's not like she tossed her in a river somewhere, or put her in the trash. If I were the judge, I would give her community service and refer her to counseling plus whatever other help she might need.
