Lori Vallow Daybell faces new murder conspiracy charge in Arizona.

Lori Vallow Daybell, also known as the "Doomsday mom," has been indicted in Arizona for conspiring to kill her niece's ex-husband, Brandon Boudreaux. She was already facing a separate felony case in the state for conspiring to kill her fourth husband. Vallow Daybell was recently found guilty in Idaho of killing her two youngest children and conspiring to kill her fifth husband's previous wife. Her fifth husband, Chad Daybell, is awaiting trial on the same charges. Vallow Daybell cannot be extradited to Arizona until she is sentenced in the Idaho case.
