Was she too stupid to call 911? NO. She wanted to be able to get rid of the baby without anyone noticing.
If she had wanted to get rid of the baby, abortion would have been a far easier option, far less pain and sickness, and no legal hassles. Going through with a pregnancy is not a way NOT to get noticed. There is a lot more to this story than "This woman is an evil, selfish witch."
Why don't you tell that to the TWO human beings she murdered?
