A research to the death of the former husband of Lori Vallow, who's under investigation in relation to the deaths of both kids, discovered he died of natural causes, police said.
The Phoenix Police Department launched an overview to Joseph Ryan's departure after Vallow was supposedly heard within an October 2018 sound recording stating"I was planning to murder him."
Ryan expired in April 2018. A medical examiner determined the reason for death was a heart attack.
It reportedly includes Vallow stating she wished to kill Ryan due to their bitter custody battle over their daughter, Tylee Ryan.
Cox, who asserted that he murdered his brother-in-law in self indulgent, expired in December of this year from organic causes.
Police are looking into Lori Vallow to get Charles Vallow's departure.
Vallow and her present husband, Chad Daybell, are billed in Idaho in relationship with concealment and other offenses about the deaths of her kids, 7-year-old Joshua"J.J." Vallow and 17-year-old Ryan. Their bodies have been located in June on Daybell's property.
She died months before he wed Vallow.
