Here are some obvious questions about the blue barrel. Sorry if these have already been asked. I've been focused on Lisa Stebic more than this case:
1. Who buys 30 gallons worth of chlorine to clean their pool. Most pools use around 2 gallons to close.
2. If Drew did purchase it for his pool, you could tell by testing his pool if he used 30 gallons. If not, ask him what he did with the extra.
3. Why on earth would anybody bring a chlorine barrel inside your house, especially into a bedroom.
4. What, other than a body, would you fill a container up so full and heavy that you need to have someone help carry it. If it was garbage, furniture, clothes, or any other normal thing you would take out of a bedroom, wouldn't you put it in several garbage bags, or smaller boxes?
5. What is the time frame around the purchase of the chlorine? How does it coincide with his closing of his pool?
6. Does a purchase of this much quantity of a chemical require a paper trail? If so, there should be a record of the purchase. Drew should need to account for the usage of 30 gallons of chlorine.
