That's one version. But in other interviews, after saying she worked at the Dojo all day, she says the drop-off was "scheduled." That means the drop-off was planned ahead...I think in different tellings...she leaves herself open for people to interpret her role any way they wish. She went from a "know-nothing" to knowing all about it.
Maybe the facts are muddled because the purpose of the cash changed. Maybe it WAS originally for something business-related, but was never supposed to go to the house. Maybe SS thought of it as a last-ditch effort to give the guy enough of something to let them go. Maybe SS thought to offer a big wad of money that he could get delivered to the house, because it was already gathered to go somewhere. So he made a bunch of phone calls and made it happen.
Maybe the psychopath's intent was just to kill some rich people and take a fancy car. Then SS tried to buy their lives with a promise of money in the morning. And he killed them anyway. Because he's a psychopath. If he got into the house at the right time, he would only have to get control of one or two people at once. Then when SS gets home, he already has hostages. There are a ton of suspicious coincidences that are ripe for interpretation and make me think someone close to the family was involved. But I can also see how this could be a solo act.
Anybody want to revisit the burned out mansion of COO Don Pyle that killed him, his wife, and four grandchildren in January? That was Annapolis, MD. It was incinerated and burned to the ground with the family inside. Remains were for sure too burned to determine cause of death. It took days to even find remains. What if this guy gets gigs at wealthy people's fundraisers at their homes? Both families did this. At these affairs there are a lot of caterers, servers, always valet parking, bartenders, coat-takers, etc. Meanwhile the help has free reign of the home and the grounds. I've been to many of these events. It would be a great way to get access for a plan.
Far-fetched?
