So... do you think she is innocent? That may explain why she did not report her daughter missing for 31 days. Oh and her partying all the time afterward.
I don't think she is innocent.. but I do not know either if she did it all on her own or if it was the result of some other situation.
As I said before, the only item that links the murder to the Anthony family is the duct tape. It is a brand found and sold only in Ohio where the family moved from so that means that the murderer is one of the Anthony's or someone who was very familiar with their home (since most people keep duct tape in their garage).
Personally, I don't believe that Casey killed the kid on purpose despite her behavior and what the prosecution said in closing arguments is very true: nobody would cover up an accidental death by making it look like murder.
So that opens two scenarios in my opinion:
1- It is known Casey was into drug parties and lots of alcohol. Chloroform is a recreational drug that does the same effects as alcohol without the hangover and it is also used to make harder drugs... so, Casey and some other person were doing this at home and somehow the kid died (I doubt it was intentional) and knowing they would be charged with murder they disposed of the body the way they did and why all the lies. The flaw in this is the tape itself: I doubt Casey or this 2nd person would go to the garage and find the duct tape to put on the kid's body (unless that tape had been inside the home and easily accessible...but then again who keeps a 4 +year old duct tape in their kitchen?).
2- Casey's father is involved. Probably same scenario as #1 except he found the kid dead and Casey drugged up and the child abuse charges are true. Thats a powerful motivation to turn an accidental death into a murder scene. This is a possible scenario because the man has decades of murder investigation experience and it is -very- unusual for a body to be kept in the trunk of a car for 10 or so days and then dumped. This is all unusual and does not make sense unless you consider that if the kid died from drug overdose and if the kid had been abused by the father then the evidence is all in the flesh and then it would make a ton of sense to purposely hide the body until the flesh is gone.
What's interesting is that all forensic textbooks describe that it takes about 10 days for a body to fully decompose in FL like weather. Also the car was kept near a garbage dumpster to hide the smell... and a corpse will start stinking after just 3 days in FL so I doubt Casey was involved in dumping the body because if she had it would not have been in the car after the 3rd day nor would the car had been hidden near a dumpster (I would think only someone who has seen bodies found near garbage dumpsters would know off the top of his head that the smell is muffled there).
In this scenario it would be Casey's best interest to avoid murder conviction and probably death penalty (drugs+dead kid=easy murder conviction) by lying (which she did best apparently) and misleading while her father would avoid conviction of abuse by disposing of the body after the incriminating flesh was gone.
A lot of things point as Casey's dad imo: The duct tape (it was his house and I would say only a man in his house would beeline for the duct tape in the garage), the knowledge of the timing needed for decomposition, knowledge of how to hide the smell, knowledge of the criminal/forensic investigation procedures and what the legal system can and cannot prove with given evidence. The man's only mistakes in this scenario was to use his own duct tape... I doubt it crossed his mind that his duct tape was of a brand found only in Ohio... and not realizing his daughter would snap under the stress and party her brain out (denial of reality).... or that her pathological lying would bring so much media attention to the case.
In any case, I doubt the case is dropped. Casey could not be found guilty of murder but you can bet that the investigators will keep at it until there is justice for this child.
