Corrections please, but I'm trying to note and catch up listening to Grey Hughes
I think two, husbands, and 4 overall have died
1) Charles Vallow (second husband? from LA who was shot by her brother, Alex Cox) who died in July 2019 and
2)Joseph Ryan (cremated body) who died November 20, 2018 (Tylee Ryan's adoptive dad)
--------
3)Alex Cox dies in December (autopsy not yet disclosed) day after Tammy Daybell was exhumed (Alex was Tammy's brother who shot Charles)
4) Tammy Daybell dies October 19, 2019. Tammy was wife of Chad Daybell, who then married Lori Vallow.
JJ/Joshua was adopted by Charles and her (from man who was 73 years old and younger wife) and has a prescription the is one which is federally followed, and hasn't been filled yet.
ETA, I'm listening to the Grey Hughes interview and updating post for the time I have for editing.
