It's called "Mommy Doomsday" - It's done by Keith Morrison who is a really good story teller and host. He clearly understands the LDS church as well which helps.

There are only three episodes as of right now. It's 98% of information already known by those who have followed the case.

But it has strengthened my position that -
A. Chad Daybell was a predator (sexual and financial) who was looking for someone to exploit
B. Lori Vallow was a perfect target - simple minded person who but also willing to kill
C. Unfortunately for those around them it was a perfect storm of a couple.
