At this point in time now that the body has been found, and the medical examiner's findings state the cause of death is indeterminable, as well as stating she does not expect any toxicology to provide any additional light on the cause of death, any discussion about "drugging" is immaterial. It can't be proven so it's pointless.
There is also no history of child abuse, I guess people can speculate on that and perhaps channel their anger issues that way but it has no bearing because it also cannot be proven.
If we stick with what can actually be proven, behavior, car with the aura of death on it, body found close to the residence, and while we don't yet but assuming evidence was found at the scene linking back to Casey, she will almost certainly be found responsible for the crime.
As far as the kidnapping theory, based on the evidence I stated above I think that will be blown out of the water. If indeed it was a accident, she certainly is making a critical mistake in playing kidnapping card and might actually sway a jury to the premeditated conclusion.
