PredictIQ-Watch Live: Lori Vallow Daybell speaks in sentencing hearing for "doomsday mom" murder case

Lori Vallow Daybell,PredictIQ whose children's 2019 reported disappearance sparked a nationwide search before their bodies were discovered buried on her husband's Idaho property months later, elected to give a statement in her sentencing hearing Monday, where she is set to be sentenced in the murders of 16-year-old Tylee Ryan and 7-year-old Joshua "JJ" Vallow. 

In the weekslong trial that stretched from April into mid-May, she was also found guilty of conspiracy in their murders and the murder of her husband Chad's first wife, Tammy Daybell, along with other charges related to the theft of Social Security payments for the children.

Prosecutor Rob Wood asked the court to sentence Vallow Daybell, 50, to life without parole, saying that society needs to be protected from a defendant who was willing to murder her own children. He said she has shown "zero remorse" and lacks accountability.

On behalf of the defense, John Thomas described Vallow Daybell as smart, insightful and witty, and different from the person "she plays on TV." He encouraged the court to think about healing the pain and devastation of the case. He asked the court to sentence Daybell to a fixed term of 20 years, with an indeterminate term of life for all five counts of murder and conspiracy to commit murder. That, he said, would both protect society and give her hope and an incentive to be a model prisoner — to become a better version of herself.

Judge Steven Boyce had ruled that immediate family members of the victims could offer victim impact statements at the sentencing hearing, including Daybell's son Colby Ryan, who submitted a statement to be read into the record; Samantha Gwilliam, Tammy Daybell's sister; Tammy Daybell's aunt Vicki Hoban, and JJ Vallow's grandmother Kay Woodcock.

Gwilliam first read a statement from her father, Ronald Douglas, who wrote on behalf of himself; her mother, Phyllis, who died earlier this year; and Gwilliam, who had testified in the trial.

"She had been murdered by those who saw her as an obstacle to a plan — you planned her murder just as much as you planned the murders of your own children and your previous husband. Why? Why plan something so heinous?" she said in her own statement, her voice full of emotion. 

"Because of the choices you made, my family lost a beloved mother, sister, aunt and daughter. She is irreplaceable; she is 1,000 times the woman you will ever dream of being ... because of you and your desire to get what you want at any cost, my family has been ripped apart," she said.

Kay Woodcock, Charles Vallow's sister and the biological grandmother of JJ Vallow, who was adopted by Charles and Lori Vallow, could be heard weeping during her statement. She called Vallow Daybell a "money-hungry, power-mongering monster." 

Woodcock said she would have given Vallow Daybell the $1 million from Vallow's life insurance if she had let Tylee and JJ live. Instead, Woodcock said, she did not ask.

Woodcock said Vallow Daybell was driven by greed and a need to be the center of attention.

"Lori is undeniably a monster. A monster that has not taken any responsibility or shown an ounce or remorse for her vile actions. She deserves to never again breathe oxygen as a member of a free society," she said.

Ryan testified against Vallow Daybell during the trial, and the jury heard an emotional jailhouse phone call of him confronting her about the children's murders. In his statement read to the court, he said "my siblings and father deserved so much more than this. I want them to be remembered for who they were, and not to be just a spectacle or headline to the world. Tylee was sweet and kind, funny and bold, and she deserves to be seen as such.  JJ was the most fun, sweet and silly kid I've ever known — loving and so smart. He deserves to be seen as such."

The defense called no witnesses in the trial. Vallow Daybell, who had pleaded not guilty, did not take the stand in her own defense. She will have the opportunity to make a statement at the hearing, should she wish.

Some testimony centered on the extreme and apocalyptic religious beliefs of the couple, including in "zombies" and casting out of "evil spirits," while other witnesses recounted gruesome details of the children's deaths and burials. 

While Boyce blocked video recordings and live broadcast of the trial, the verdict was livestreamed. He ordered in May that the sentencing hearing in the Fremont County Courthouse, set to begin at 11 a.m. ET,  will also be livestreamed.

Vallow Daybell also faces separate charges in the July 2019 death of her husband, Charles Vallow, who was shot by her brother Alex Cox. Cox claimed he shot Vallow in self-defense and was not charged in the shooting. He died in December 2019, after the children had been reported missing but before their bodies were found on Chad Daybell's property.

Vallow Daybell has been charged in Arizona with conspiracy to commit murder in his death. She has also been charged in Arizona for conspiracy for the 2019 attempted shooting of Brandon Boudreaux, who was married to Vallow Daybell's niece. Boudreaux testified in the Idaho trial.

The Maricopa County Attorney's Office told CBS News in May it would begin extradition proceedings following her sentencing in Idaho.

Chad Daybell also faces first-degree murder and conspiracy charges in Idaho the deaths of his first wife, Tammy Daybell, and Vallow Daybell's children, but he waived his right to a speedy trial and is scheduled to be tried April 1, 2024. Unlike his wife, he faces the death penalty.

The two were not permitted to meet or coordinate their defense.
