Well, some may have been sold on the smell by power of suggestion? There are many more people involved who have had experience in human decomp who didn't smell anything. I would think everyone involved would've smelled it, not just a select few. And, if (a big IF) GA and the towyard manager truly smelled human decomposition, why didn't either one of them call the police?
I understood the manager to testify that he's had many vehicles with bodies in the car on his lot. When someone manages a lot like that, picks up a vehicle that he believes to have a dead body in it, isn't it required for him to notify the police to either find the owner or open the car up? If that isn't done, isn't that hindering an investigation? Or something like that? This manager was closely involved with LE, why wouldn't he just make a quick call to find out about the car? Or, when GA left with the car why not just mention since he was saying his daughter/granddaughter were missing, mention to LE that the car smelled like decomp? No, instead you wait until you hear the news that the child is missing and the mother is a suspect.... THEN you come clean with this information? And THEN is when LE decided to pick up the vehicle. Not before, when everyone was around the car and should've clearly smelled human decomp.
