As much as I've been following this case, did LE ever confirm there was pizza in the car at all? Or was this something they just "threw out" like the receipts? My whole opinion of Cindy really turned when she said "Well, I had all these receipts to show LE, but they waited and now they're gone." Sure. Fine. Whatever.
My mom is a RN. I'll have to ask her, but usually the bodies don't stick around too long in a hospital setting. Maybe in nursing school, or if they did a rotation where they had to go view autopsies. Good point. Someone in the medical profession might very well know what a decomposing body smells like, if they were in the right settings.
