Negligent manslaughter might have had a chance, but she wasn’t charged with that. Even then, they would have to have proved negligence. Not reporting her missing isn’t sufficient to prove that.
I don’t know what they were thinking with the child abuse charge — there was zero evidence of abuse.
She’s guilty as hell of lying, and someone is guilty as hell of concealing the body, but only Casey was on trial, not anyone else.
Well, not reporting a 2 year old missing for a month, while you go out partying in the mean time, pretty much fits my definition of negligence - at the very least. Later finding the child dead, buried and wrapped in a garbage bag pretty much proves the concept. Not to mention that we live in a world where people are arrested for leaving children alone in their own cars for five minutes. So how this escaped - at the very least, not counting anything else - negligent manslaughter is, to my way of thinking, a legal atrocity.
But that's just me.
