Lori Vallow Daybell, the Idaho woman serving life in prison for the murders of her two youngest children and a romantic rival, was sentenced to two consecutive life sentences in Arizona for conspiring to kill her estranged husband and attempting to murder her niece's ex-husband.

Vallow Daybell, often referred to as "Doomsday mom" because of the apocalyptic beliefs that fueled her string of grisly murders, was convicted earlier this year for the murder of her former husband, Charles Vallow, and the attempted murder of Brandon Boudreaux in 2019.

"The amount of contemplation, calculation, planning and manipulation that went into these crimes is unparalleled in my career," Judge Justin Beresky said before sentencing Vallow Daybell on July 25. "It will take an act of god for you to go free."

Vallow Daybell is already serving multiple life sentences in Idaho for the 2019 murders of her children, Joshua “J.J.” Vallow and Tylee Ryan, along with the killing of her current husband’s former wife, Tammy Daybell. Her two life sentences in Arizona will run consecutively.

Family members of Vallow Daybell's victims testified for more than an hour at the July 25 sentencing hearing about harm she caused. Her only surviving child, Colby Ryan, described the moments when he found out his father had been shot and killed and then later, when he learned his 7-year-old and 16-year-old siblings had been murdered.
