And did they use a Gmail account, for example, to open up that account?

Then all of a sudden you can send a subpoena or a search warrant to Google to get those Gmail records.

Do you have a cell phone provider that was used here?

Can you triangulate location based on cell tower data?

So a Bitcoin address when the funds are ultimately moving is a great investigative lead, but that's when law enforcement uses all those other tools that they have in their toolbox.

Absolutely.

You essentially have an investigator likely in an office in front of a laptop or a computer who's in a tool like TRM.

You know, it's an application that actually shows funds moving on a blockchain.

There's a user interface that creates graphs and you're saying to yourself, all right, I'm looking at that initial address that's in the ransom note.

Where are funds going?

And then you start tracing and you have these really cool graphs that are following the money in real time.

The problem is you need that initial payment in order to start that activity and open question about whether or not we have that today.

So that crypto address is a very, very powerful investigative lead.

But again, you need a payment to be made one way or another.

It is an Adult Protective Services card belonging to an advanced investigator by the name of Deborah M. Her name is written on the card.

An advanced investigator with Adult Protective Services in Tucson would be a professional field investigator employed by the Arizona Department of Economic Security's APS unit, whose job is to investigate reports of abuse, neglect, exploitation, or self-neglect.

And in this case,

When Nancy Guthrie was reported missing, APS got involved, and that's why the card was placed on the door.

There was nobody home at the time that Deborah placed the card in the door.

Absolutely correct.
