We are in a Berkshire Podcast Festival hangover. We're also in the midst of processing some big new information. Enjoy this bonus episode. We'll be back next week.

In this new subscriber-exclusive series, Josh talks about what didn't make it into the episodes, new information on old cases, the music behind the episodes, and more.

This week, he's sharing updates in the Spierer, Burt, Marl, and Maddux cases. He discusses details on the LaPlace cache and what it was like identifying it. He goes over his investigation priorities over the remainder of season six. We talk about the featured music played in the last two episodes. And finally, we talk questions and topics for Josh's impending interview with FBI Agent Ted Halla.
