Lori Vallow Daybell sentencing: 'Doomsday' mom gets life in prison without parole

Samantha Gwilliam, the sister of Chad Daybell's wife Tammy Daybell, who died of asphyxiation in 2019 less than one month before Chad and Lori Daybell married, took the stand to give a victim impact statement.

Gwilliam testified that Chad Daybell told her that he'd married Vallow Daybell two weeks after her "beloved sister," Tammy Daybell, was buried, and claimed the new couple then told lie after lie.

"Because of you and your desire to get what you want at any cost, my family has been ripped apart. I helped raise Tammy's children and because of you they no longer have their mother or grandmother," Gwilliam said.

Choked up, she said her relationship with Tammy and Chad Daybell's children is "strained and most contact with them is gone" she said.

"Your trial is the last thing my ailing mother had to live through," she said, adding that her death in June "was marred by the fact that Tammy's children chose not to participate in her funeral by fear of causing more drama."

"We blame you and Chad for all the lies you told in ripping apart this family," she said.

"I choose to forget you … I choose to never think of you again," she said.

Gwilliam also read a statement on behalf of her father, Ronald Douglas.

"Tammy's death was unexpected and had a profound impact on all of us," Douglas' statement said, adding "we were barely into our recovery process" when learning that Chad Daybell had remarried weeks later.

"The emotional stress" accelerated Tammy Daybell's mother's declining health, he noted.

"The eternal ramifications of [Vallow Daybell's] actions are yet to be calculated. Lori needs to pay," he said.

Chad Daybell is charged with Tammy Daybell's murder and conspiracy to commit murder and pleaded not guilty. Vallow Daybell was found guilty of conspiracy to commit Tammy Daybell's murder.

Multiple people sought to give victim impact statements at Monday's sentencing hearing on behalf of Tylee Ryan, J.J. Vallow and Tamara Daybell, according to a June court filing.

Those granted permission to address the court include Colby Ryan, the half-brother to Tylee and adoptive brother to J.J.; Summer Shiflet, the sister of Lori Vallow Daybell; and Kay Woodcock, a representative of Charles Vallow, who was J.J.'s adoptive father and Lori Vallow Daybell's late husband. Vicki Hoban, the aunt of Tamara Daybell, was also later granted permission to speak as a designated representative of Tamara Daybell's late mother.

Idaho law allows the "immediate family members" of homicide victims to address the court.

It was unclear ahead of the hearing who was scheduled to address the court.

Ahead of Lori Vallow Daybell's sentencing, defense attorneys unsuccessfully sought a new trial.

On May 25, the defense filed a motion for a new trial, arguing that the jury instructions were "confusing" and "prejudicial," among other claims.

Judge Steven Boyce denied the request for a new trial on June 15.

The jury handed down its verdict in mid-May, after deliberating for approximately six hours across two days. The verdict was read before a packed Boise courtroom and also livestreamed by the court.

The verdict followed a six-week trial during which prosecutors argued that Lori Vallow Daybell and her husband Chad Daybell thought the children were zombies and murdered them. Prosecutors called roughly 60 witnesses, while the defense called none.

Prosecutors said at the time they were "very pleased" with the jury's verdict but declined to comment further given the pending case against Chad Daybell. His case is scheduled to go to trial in April 2024.

Joshua "J.J." Vallow and Tylee Ryan were last seen alive in September 2019 and were reported missing by their extended family members to police in November 2019.

Their remains were found on Chad Daybell's property in Fremont County, Idaho, in June 2020. Lori Vallow Daybell and Chad Daybell were indicted on murder charges nearly a year later.

Among the revelations during Lori Vallow Daybell's trial, a DNA expert testified for the state that a strand of hair attached to duct tape found among the remains matched the mother's DNA profile.

The jury also heard text messages that prosecutors said were sent between Lori Vallow Daybell and her husband in the weeks prior to her children's disappearance.

The messages discussed demons inhabiting the children's bodies and that they were "weary" taking care of demons. Lori Vallow Daybell reportedly texted her husband to "please ask the Lord to take them" and, days later, if he thinks there is a "perfectly orchestrated plan to take the children," to which he reportedly responded, "There is a plan being orchestrated for the children."
