Child abuse is the intentional infliction of injury upon the child ... You can postulate a number of different hypotheses in this case. Some might say well maybe she put the duct tape on Caylee to make her stop crying because she was loud. Casey put it on too tight and Caylee died by accident. if that is what you think happened, that is felony murder. so if that is something you're thinking about, that's also first-degree murder.
Or if you choose to believe that you use chloroform so she could spend time with her boyfriend. Let's say she is the chloroform in the trunk of the car and Caylee accidentally died. It is still first-degree murder one that makes the most sense is premeditated. Anyway put it together Casey Anthony is guilty of murder in the first degree.
