Interesting comment, thanks.
Might be relevant.
This case is crazy back and forth in the possibilities of the perps.
Might be family.
Might be staff of Nancy's who were in charge of yardwork, kitchen/cooking, cleaning, etc.
One possibility I'm not convinced of yet, is a random passerby who knew somehow that Nancy lived alone and took advantage of an elderly woman -- because--what would they gain by taking her with them, as opposed to a smash & grab ?
That bit (pun intended) about the bitcoin/cryptocurrency able to be tracked was new to me !
Now am back to considering the employees who may have been casing Nancy's house.
Omo.
I agree, the case keeps shifting because there are still a lot of unknowns, and without one confirmed anchor point everything remains open.
From a behavioral standpoint, opportunistic “random passerby” scenarios usually aim for speed and low risk, such as a quick theft. Taking a person dramatically increases risk, time, and exposure, so in most cases there is usually some perceived value, motive, or prior awareness involved. That does not automatically mean someone close, but it often suggests some level of knowledge about routines, vulnerability, or environment.
When people look at staff or familiar individuals, it is usually because those roles naturally have visibility into daily patterns, timing, and household details. However, that alone is not evidence, just one of several possibilities investigators typically examine early in a case.
On the cryptocurrency point, many people are surprised by that. Bitcoin transactions are permanently recorded on a public ledger. Investigators do not “break” Bitcoin, they follow the flow. In many past cases, funds believed to be hidden were eventually linked once they touched exchanges, services, or a real world identity. The technology itself often is not what exposes someone, it is a small human or behavioral connection.
Right now it feels like the case is waiting on one verified detail that will narrow the field significantly. Until that appears, multiple paths remain possible.
