If the jury buys that the duct tape is the murder weapon because of Dr. G's argument and JA's indication it was unnecessary to cover the breathing apertures of a living child, then they may go with premeditated murder. One piece, maybe not. But three long pieces of duct tape applied is calculated and gives enough pause for reflection. If the jury is a bit unsure of the premeditation part, perhaps where the google searches for various ways to kill or maim people will help the jury tip in that direction.
I don't see the felony manslaughter charge on the list. If it is indeed a felony to administer chloroform to a child and use duct tape to tape a child's face, and the result is death for a child under 12, then that puts the sentence in the same place as Murder One in the state of Florida.
The consciousness of guilt evident by hiding Caylee's body in plastic bags and a canvas laundry bag, and the cavalier way her remains were disposed of, may also be a factor in the jury determining that this was a purposeful homicide.
The jury may think that certain forensic aspects are weak when considered individually, but when considered as an aggregate, I'd think they would point to some charge that has LWOP. Although this jury is exhausted and may not want to go through a prolonged mitigation phase, so they may not convict on the maximum. I'm having a rough time predicting what this jury might do seeing as how we've heard so many stories about this juror or that one. Oh well, as CM said, time for those people to light some candles. I just hope they remember who they should be lighting them for - innocent little Caylee who had her voice silenced without her permission.
