Donna7777,
This is MOO, but as I stated in my post yesterday what I think happened is that JR & LD planned to take Joey out of the bldg in suitcases, which is why they called for the cart. I think they couldn't fit him into hard cover suitcases so they put him in the duffle bag. I think they realized that because of the soft, unstructured fabric of the duffle bag, one could make out the shape of Joey's body in there. They probably threw him out the window to avoid being seen with something that looks like a body. I believe they put empty suitcases on the cart because it would be odd and suspicious to call for a cart and return it with nothing on it. It's JMO but I don't think we hear anything about the suitcases because Joey wasn't in there. In other words, the suitcases were just props to justify calling for the cart when they realized they couldn't use it to bring Joey's body out the front door. JMO
