Ampulla of Vater
Illuminator
I think she should have pled temporary insanity citing postpartum depression.
I don't think that's the truth, but that's what she should have done. Sixteen different ways to have the event happen indicate some consciousness of guilt. Which is why she should have pled the above. She did it, that's what the evidence shows. Since we heard Darin stomping down the stairs, he didn't do it. That leaves Darlie. Not a whole lot of choice since Drake couldn't get out of the crib to do it and the dog lacked opposable thumbs to hold the knife.
Amen, sister.
