I'm not referring to when the A's picked up the car, I'm referring to when LE picked up the car, IIRC it was July 17th after SB called LE to report his knowledge after watching the news. Notice, he didn't report his knowledge when he believed it smelled like human decomp, he waited until he saw the case all over the news.
I don't believe the officer who secured the car knew anything about it. I could be wrong, but IIRC, she only testified to securing the car and not smelling anything. As far as the other LE who were at the A's house that night, some/possibly all have smelled human decomp before, but didn't find it necessary to automatically secure the car and declare it a crime scene. They bought the trash story because the smell wasn't distinct to human decomp, IMO.
Snipped the logic stuff, because I'm hoping it doesn't need to be posted anymore.
