Lori Vallow Daybell, the Idaho woman serving life in prison for the murders of her two youngest children and a romantic rival, is set to be sentenced July 25 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 previously convicted for the murder of her former husband, Charles Vallow, and the attempted murder of Brandon Boudreaux in 2019.

She 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.

Vallow Daybell was found guilty of conspiracy to murder and attempted murder by two separate Arizona juries earlier this year.

Prosecutors alleged Vallow Daybell and her husband, Chad Daybell, believed an apocalypse was imminent and people around them were evil zombies. They accused Vallow Daybell of manipulating her brother and husband, Chad Daybell, into carrying out the crimes to cash in on Social Security benefits and a life insurance policy.

Prosecutors asked for life sentences in both Arizona cases, citing Vallow Daybell’s prior convictions, the emotional toll on victims’ families and alleged financial motives behind the killing of Charles Vallow. After sentencing, she is expected to be transferred back to Idaho to serve out her sentence.

The murders of Charles Vallow and Brandon Boudreaux

Vallow Daybell met her current husband, Chad Daybell, in 2018 at a religious conference in Utah. The pair bonded over their shared religious beliefs, including that an apocalyptic doomsday would soon be arriving.

Shortly after, in 2019, Charles Vallow filed for divorce, claiming that his wife had threatened to kill him and believed she was a godlike figure preparing for the second coming of Christ.

Vallow was shot at Vallow Daybell’s rental home in Chandler, Arizona, in July 2019. Months later, her niece’s ex-husband, Brandon Boudreaux, was shot at while driving in Gilbert, Arizona. The shooting was later tied to Vallow Daybell’s brother who had begun to share her apocalyptic beliefs.

The murders of Joshua Vallow, Tylee Ryan and Tammy Daybell

Vallow Daybell moved in September 2019 with her children to the small Idaho town where Chad Daybell lived with his then-wife, Tammy Daybell. Weeks after the move, Tammy Daybell was found dead of asphyxiation.

Relatives of Vallow Daybell soon after reported to police that they had not seen her children.

Vallow Daybell was arrested in February 2020 in Hawaii, where she and Chad Daybell got married, on child abandonment counts. She was extradited to Idaho, and in early June, authorities found the bodies of her children buried on Chad Daybell’s property.
