The Maricopa County Attorney’s Office has started the process to try to extradite former Arizona resident Lori Vallow Daybell to eventually stand trial on charges of conspiracy to commit murder.

MCAO has delivered paperwork called requisition for extradition that, if approved, would require Vallow Daybell to stand trial in the Valley stemming from her alleged role in the death of her fourth husband, Charles Vallow, and also of allegedly conspiring to kill her niece’s ex-husband, according to the Associated Press.

Last month, Vallow Daybell has been sentenced to life in prison without parole in an Idaho courtroom.

The Arizona extradition could not begin until the sentence in Idaho was complete, said Jeanine L’Ecuyer, spokeswoman for the Maricopa County Attorney’s Office.

On Wednesday, the requisition for extradition paperwork was delivered to the office of Gov. Katie Hobbs, who must sign off on the arrangement along with Idaho Gov. Brad Little, L’Ecuyer said.

That process could take three to six months, she said.

Vallow Daybell, 50, was found guilty in May of killing her two youngest children — 7-year-old Joshua “JJ” Vallow and 16-year-old Tylee Ryan — as well as conspiring to kill Tammy Daybell, her fifth husband’s previous wife, the AP reported. Vallow Daybell will serve three life sentences one after the other, the AP reported.

Her husband, Chad Daybell, will stand trial on the same murder charges as Vallow Daybell, according to the AP.
