Item #6 really stands out to me. I would be willing to bet that Bob never pawned anything in his life. He was prudent and cautious with his money. That makes me wonder who actually pawned the jewelry. I doubt dear Bob knew anything about it. The motive for this crime may have as much to do with preventing Bob's financial advisors from having a look at his books, and discovering malfeasance, as it does preserving what was left of his estate. From their own statements we know that JuM had access to his records and AH had some of his computers at Bob's house.
