So obviously for those who don't know genetic genealogy, it's kind of like those 23andMe tests, isn't it?

Where you are going back to trace your family history and you take a swab of your DNA and you send it off.

and you get back any potential hits or leads on your relations.

And when they did find their guy, that was it wasn't until 2020 that the actual trial took place.

So what year was that?

So we don't really have a sense of what kind of individual Joseph D'Angelo actually really was, per se.

How did you go about kind of, I suppose, for the book, how did you go about kind of getting those sources and bits and pieces together?

And in 2020, Joseph D'Angelo pleaded guilty to 13 counts of first degree murder and pleaded guilty to 13 counts of kidnapping charges.

What sentence did he receive?

And obviously, Brad, this is a case that's obviously been extensively covered.

You know, there's a lot of books written and it got a lot of media coverage.

But why did you decide to write this book?

I think as well, it's the fact it's remained, he remained, you know, undiscovered for so long as well.

There's that air of kind of mystery surrounding it and that we now know.

And it was actually just like modern technology that kind of ironed it all out.

But it's a very, very interesting case.

And the more I read up on it, it's really, really interesting.

But Brad, your book, Inside the Mind of the Golden State Killer is available now.

Can you tell us where you can get it?

Fantastic.
