I just listened to the second half of the podcast this morning. I have some thoughts on it.
They spend a bit of time on the pocket dial call, and this is the first I've heard of other experts having weighed in on it. Apparently they can't get much of anything useful out of it either. Glad to know it's not just me. I not only can't hear anything coherent in it, I also don't hear the emotion and arguing Gasparoli purports to, either.
I do think the theory that Faith was killed by mistake instead of KR has merit. It's interesting that Gasparoli prefaced that whole topic by saying there are reasons why it doesn't make sense. I just wish he'd elaborated on what he thinks they are.
Finally, I know there are different opinions on this, but I've never been persuaded that there had to be multiple people involved in the murder, either as participants or conspirators. To me, the DNA evidence suggests otherwise, and the more people who know about something, the harder it is to keep it a secret.
