Daybell predicted death percentages for victims

The State of Idaho's last witness is retired FBI agent Doug Hart who walked the court through disturbing text messages between Chad Daybell and Lori Vallow. The messages were exchanged in 2019 before the death of Tammy Daybell, Chad's first wife. Daybell discussed "death percentages" he came up with specifically for Tammy and JJ Vallow, the adopted son of Lori Vallow.
