Hopefully they will get her on child endagerment, or something she has already admitted to leaving the child unattended in a car for over an hour, to me that is enough in itself to jail her
That sounds highly plausible. At the very least we have criminal negligence. I looked this up in one of my Criminal Law books when catching up on the Conrad Murray trial for those who are interested:
"Gross Negligence Flagrant or shameful acts which constitute a failure to use reasonable caution or care which results in harm to another person"
McCord, James W.H., et al, Criminal Law and Procedure for the Paralegal, A Systems Approach, 4th edition, pg 93-4
"Recklessly means knowing that there is a substantial and unjustifiable risk that conduct might cause a particular result but not intending the harmful result
In being reckless, the perpetrator does not knowingly or purposefully intend the harm, but purposefully or knowingly creates a substantial and unjustifiable risk that the harm may occur.
"Negligently means thoughtlessly or carelessly creating a significant unjustifiable risk of harm without realizing the risk has been created or without the intent to create the risk, yet the act or failure to act is such that a reasonable person would have known that it created the risk. There is no intent to harm or even a thought that the act will cause harm, but to a reasonable person the risk is apparent and should have been avoided."
McCord, James W.H., et al, Criminal Law and Procedure for the Paralegal, A Systems Approach, 4th edition, pg 60
I wouldn't be the least bit surprised if LE pulls a Casey Anthony and arrests her tonight for endangerment or neglect and then keeps questioning her to find out where the baby is.
