They didn’t look outside, won’t ask 6 and 8 year olds if they recall hearing/seeing anything, never tried to call their cell phones to see if someone answered and keep going in front of the cameras to explain her “adult time” drinking. The defense will try to turn this into a distraught woman who just didn’t know what to do when the baby died accidently.
No doubt you are right, it will be an accident defense. However if they find the body in time, the evidence may prove otherwise.
I don’t know what happened but my best guess is that the mother shook her because she wouldn’t stop crying.
