According to the prosecution, the Pontiac was a crime scene. The bag of trash was entered into evidence. George Anthony owned the car. Outside of his testimony, he was the last person to see Caylee alive. A former police officer, he removed evidence from a crime scene after stating it smelled like a dead body. Yet he was never a suspect.
With one simple assumption, all of the mysteries are solved. Of course, we can’t factually know what happened to Caylee Anthony. However, after listening to the evidence from both sides, this is the only story that makes sense to me.
