Is it possible that KC drugged Caylee, taped her face, and put her in the garbage bags while she was still alive? Then into the trunk for 3-5 days trying to figure out what to do. The canvas laundry bag would have been a good cover at first--until decomp fluids and odor began to seep out. I hate to think Caylee was left like that in the trunk and THEN died, but the time frame of disappearance to decomp smell, etc, seems to fit this idea. Maybe a dumb idea, but an idea nonetheless.
