'Doomsday' mom Lori Vallow Daybell, convicted of killing 2 children, faces new charges in Arizona

 A woman convicted in the deaths of her two children and a romantic rival faces new charges in Arizona after being accused of conspiring to kill her niece's ex-husband.

Lori Vallow Daybell, whose case has drawn widespread attention and outrage around the world, was found guilty last week for killing her two youngest children – Joshua "JJ" Vallow, 7, and Tylee Ryan, 16 ‒ and conspiring to kill Tammy Daybell, her fifth husband's previous wife.

The verdict came nearly three years after the children's bodies were discovered in the backyard of Vallow Daybell's husband, Chad Daybell, near a "pet cemetery."

Vallow Daybell already was facing separate felony charges in Arizona after a grand jury indicted her in 2021 on a charge of conspiring to kill her fourth husband, Charles Vallow.

The second indictment in Arizona, which was unsealed this month, involves charges of conspiring to kill her niece's ex-husband, Brandon Boudreaux, according to the prosecutor's office in Maricopa County, Arizona.

Police say Vallow Daybell's brother, Alex Cox, shot and killed Charles Vallow in July 2019 and shot at Boudreaux in October 2019, but missed.

Last week, prosecutors argued Vallow Daybell used sex and power to manipulate her brother and husband into carrying out the crimes. The case involved graphic details of police finding her children's bodies and claims she called the children zombies and saw herself as a "sexual goddess" in a Biblical apocalypse.

Vallow Daybell faces life in prison for killing her children, and the other charges against her also carry a life sentence. Chad Daybell, is being tried separately and could face the death penalty if convicted.
