Wow. For a security guard he had alot of cash to spend. Airline tickets. $9000 for jewelry. Guns. Ammo.
This money came from whom?
You forgot to mention the house as well.
I think his dad was tossing him at least a thousand a month for the lifestyle he was living. Dad paid for the house as far as I can see. I think the bigger question is where dad makes his money.
If he used a credit card to buy the jewelry, perhaps the bank can help find her. /s
