It is my opinion, based on the evidence released so far, that Casey is guilty of the premeditated murder of Caylee. I understand some's concern with murder vs premeditated murder.
I went back and read the motion by the defense in which they were arguing to include the complete definition of "premeditated" in jury instructions. this motion was filed on Nov 25, 2009.(I tried to include a link but I couldn't figure it out, sorry. I read it on the cfnews13 website.) The verbage the defense used in their motion...
1. more than a mere intent to kill
a fully formed purpose to kill and
2. must have existed for a period of time long enough to permit reflection
a. as to the nature of the act; and
b. to the probable consequences to the victim.
Ok, let's think about this for a minute. Any rational, reasonable adult can infer that if you duct tape a 2 year old's mouth and nose with 3 pieces of duct tape that they will not be able to breath. Without breathing, they die, very simple. If you are the person applying the tape you definitely don't just have the mere intent to kill, your purpose is to close that person's airway and kill them so you have "fully formed the purpose to kill."
In March of that same year, months before Cindy reported Caylee missing, Casey conducted internet searches on how to make chloroform, neck breaking, household weapons and visited missing children websites. If you intend to use chloroform on a 2 year old or break the neck of a 2 year old, your intent is to cause major damage, if not kill. Someone might argue that you can't say with any certainty that Casey searched those things to use on Caylee. Well, I might agree, except there is a slight problem with that argument...there were traces of chloroform in her car and these searches are in the same time frame as searches on missing children sites.
A couple of months covers the "period of time long enough to permit reflection" and premeditation can occur minutes before the crime is committed so I'm being generous. I think a couple of months is plenty of time to reflect about the nature of the act and the probable consequences to the victim as well.
So, even if I use the defense's definition and words about premeditation (and mind you they want these, or something similar, included in jury instructions) she meets these requirements.
IMO, she definitely meets the criteria to be charged with and convicted of premeditated murder.
