Okay, so I have a weird theory. CEO was separated from a wife who was kind of weird when asked about death threats to husband. Killer had silencer, training, and the exact movements of his target. I think it's possible that she hired him and had the bullets altered to reinforce that it was an angry customer. Just a thought.
I have half a bottle of yummy wine the boy bought us, hidden in a cup so the twins don't beg. Not a terrible day. If the wine pees out in cash. Otherwise, DOOM! And I'll drink the other half of the bottle. And then the Happy Elves will come and all will be better! Until I wake up. Then more elves!
