I don't know who all is involved, just I'm pretty sure he/they weren't only after $40K...whatever the plan was, things did not go according to plan. Whether or not you're intending a quadruple homicide and whether or not you're acting alone, planning to take hostages for $40K from a multimillionaire family seems both an odd number and a low number. That all the cash is in the specialized box truck (and that this vehicle is even being used) with DW in the other car and that those people have been released, I'm thinking there's some thing or things very valuable that are being stored somewhere and LE is waiting for those involved to go to this valuable stuff. If for instance PS owned a go-kart that he used in racing, something like that would fit in the box truck, there could be very expensive big screen TVs, sword collection, etc that were moved out of the house. I can't imagine that DW and whoever else are spending hours upon hours in a mansion with lots of very valuable items and not taking them and instead purely focusing on the cash...there are criminals who have the self-control to just focus on cash or one other specific item, but those sorts of criminals would be going for more than $40K unless it was a lightening fast job where the money was already expected to be there. LE may be saying DW had to have help because something too large or heavy for one person to carry is missing.
