Is it possible that the garbage bag or something in it was the actual source of the decomposition smell? I do not mean that the pizza produced the smell of death. I keep thinking if the smell was not there on 6/24, then maybe the bag with the nasties was the only changing factor. Does that make sense? Say, what if a decomposing body was on or around the garbage bag, pizza, or whatever else in the bag? What if the scent was absorbed by one of these things, then it was placed into the trunk. Sometimes when I want to put something dirty or smelly in a car or house, I will place the smelly thing in a bag. Then lay down a garbage bag on the floor, and place the thing on top of the flat bag. If something oozed out, it would stink up the bag. This happened when I was transporting a kitty litter box in a bag on another bag within my sister's car. Surprisingly, the flat bag smelled like cat pee afterwards and it was not in direct contact with the litter box.
