She wanted to listen to a podcast, so I suggest Cold. She had heard of the Susan/ Josh Powell story, but wasn’t familiar with all the details.
Anyway, we start listening as we get further into it and realizes what may have happened to Susan’s body, she turns white...apparently, her sick ex-husband used to always make comments that he could dump her body in the desert in a mind shaft and that nobody would ever find her body and so he’d never get charged with murder. Things he’d say were very similar to what many speculate Josh Powell did with Susan’s body. Needless to say, we stopped listening to the podcast.
