She did drive around with the odor coming from the trunk. When did she go to a friend's house to take a shower?
I know she drove around with the smell. I was saying Casey also knew what the SOURCE of that smell was. IFFFFF JB wants to say it was simply a bag of garbage/trash/velveeta/gatorade bottle/whatever....then SURELY Casey would have removed that bag to stop the odor from continuing to grow.
