I've got an insy-winsy baby of a theory. Something like this: a person from Boulder or nearabouts, perhaps had some money invested (sold their rights in an invention or a business, in return for shares in another company) and they ended up with worthless paper. (It happened quite a bit around here for a while. Companies looked good on paper and then went belly-up, or when they were discovered to have overstated the value of assets, $10 shares became 10c shares.)
Anyhow it was 'all they had' so eventhough it seems small potatoes to us, they were very keen to get it back. The company I envisage is probably not AG, but something to do with LM, perhaps even an acquisition that was 'asset stripped'. So they see JR in the newspaper with $1B sales and focus all their hatred on him as an 'employee' of LM and someone rolling in money.
They 'engage' a couple (or 3?) people (family/acquaintances) to pull a little scam. These people let themselves into the Rs house while they are out and wait inside till everyone is alseep. Then they creep upstairs and capture the smallest kid, that cute little 6yo. (Perhaps one of the people was known to her so there's a possibility she was 'lured' downstairs -- I keep thinking of a Santa Suit). They take her downstairs and hide her (tied and gagged and wrapped in the blanket) in the wine cellar or crawlspace. ***** (see below) They leave (via a door) and get into their car/van and wait till nearly morning then call JR on the phone (via their mobile) and read out the RN. They then keep tabs on JR while he gets the dough and goes back home. When he gets home, they call again and instruct him where to leave the dough. They follow him there and back home and make sure no-one (FBI, cops) is watching, (maybe leave one or two watching the dough), call the 'boss' to make the pick-up. When this is done money safely in hand, they call the Rs and let them know where they can find JBR (in the basement/crawlspace).
They just have to make sure they don't leave fingerprints, so all are wearing gloves and coveralls. It's a sweet plan and once out of the house, it's risk free. One makes sure he knows where JR is at all times the others watch the money to ensure it's not a trap. All can escape if it turns out he has called the cops.
**** This is where the plan went wrong.
One person was left with her. It was a bad choice. When the other(s) go downstairs to find out what's keeping him. OMG!!! He's killed her!! And he's gone!! The accomplice cleans her up, pulls up her pants, drags her into the winecellar and gets the hell outa there. So much in shock he forgets the RN lying on the stairs where he was reading it, forgets the flashlight. Scarpers home as quickly as he can.
While I believe its SFF, and you in company-related revenge, we are both willing to be wrong if it means justice, right?
Anyway, to adapt your style to my theory, it would sound a lot different:
This one powerful guy has grown to hate the capitalist way of life not just a little but a lot. He was raised hating Americans. He especially hates rich children showing themselves off and could even hold them responsible and not the parents. An ideological mission, serial killer or Kaczynski-style, to remove unwanted people from the earth.
He's a crazy sociopath and is used to sadistical affairs. He gets everything he wants and always has. Whats left? Little kid fantasies? As Smit said, a pedophile's dream, right? He's kidnapped before, killed before, beheaded before. And denied people proper burial before.
Nobody misses him on Christmas night as he's neither an American family man nor a Christian. But he does get everything he wants and a small American girl is going to be one of them. Part revenge, part sadistic fantasy, part child fantasy.
He plans for months, travels for days, and his paid accomplices have already staked out the house communications and all. The accomplices THOUGHT it was to be a kidnapping because he spent the WHOLE AFTERNOON writing the RN and it says so long as JR plays along the girl is returned.
Instead of the ransom kidnapping, the sadistic fantasy plays out complete with bizarre sexual assault, strangulation and headbash. What are the accomplices going to do? Come forward? I dont' think so.
A massive narcissist is probably understatement. He's got it all worked out that this and everything else he does is OK and doesn't care if he strikes fear into his close associates.
Probably easily recognized as a megalomaniac.
