As regards this being a premediated murder proved beyond a reasonable doubt, the answer is: No.
If you hold otherwise, please, first, cite the fact (or facts) that your inferred conclusion of "guilty" relies on that has been proved to be true beyond a reasonable doubt. Second, using that fact (or facts), layout the premises that are the basis for your, necessarily, highly reliable conclusion of "guilty".
(The certainty of an inferred conclusion can be no greater than the certainty of the facts in the premises.)
Fact...Casey didn't report her daughter missing or call for help because of an accident.
Fact...Casey was the last person seen with Caylee alive.
Fact...Decomposing head hair of Caylee's was found in the trunk of Casey's car the exact day that Casey told the police that she had "spoken with" Caylee.
Fact...Caylee was found dead, and their were three layers of Henkle brand duct tape over her mouth and nose.
Fact...The Henkle tape would cause death to a anyone when applied in the manner it was found , thereby it IS what caused Caylee's death.
Fact...That particular tape found over Caylee's mouth and nose, came from the same source as the Henkle tape used at Casey's house.
NOW, the totality of THAT evidence tell me all I need to know.
Therefore, I conclude beyond any reasonable doubt, that while CASEY was putting the Henkle brand duct tape over the mouth AND nose of her daughter Caylee, she had the time to reflect that this MAY kill her daughter and chose to apply, both the second and third layers!
Is that what you are looking for Wudge, because, I think the three layers of duct tape prove pre-meditation in the application. Therefore, MURDER in the first degree, premeditated.
