The smell was still there. Caylee’s body was gone. Apparently the jury believed it was the smell of garbage, as they defense suggested. There is no mistaking the smell of garbage from that of a dead body. It is a smell unlike any other, and the people that were even near the car (like in the impound lot) knew what that smell was. That is why the prosecution wanted the jury to smell the air samples from the trunk. The judge did not allow that.
My house floated away in a flood once......the smell of flood mud was horrendous.....to THIS DAY I recognize that smell...it is like no other. I imagine a dead decomposing body to be the same.
