Investigators for years have believed that Chad and Lori Vallow Daybell conspired to kill two of her children, along with Chad Daybell’s first wife. The lengthy criminal case is one step closer to ending after an Ada County jury convicted 52-year-old Chad Daybell for the murders Thursday.

Now, that same jury will decide whether the Rexburg man should be sentenced to death.

Chad Daybell was convicted on eight felonies, including the first-degree murders of his then-wife Tammy Daybell and Vallow Daybell’s two youngest children: 7-year-old JJ Vallow and 16-year-old Tylee Ryan. He was also convicted on three counts of conspiracy to commit murder and two counts of insurance fraud for increasing Tammy Daybell’s life insurance coverage.

The 12-person jury reached the verdict after roughly six hours of deliberation — shorter than it took the jurors to find Lori Vallow Daybell guilty. Lori Vallow Daybell was convicted on six felony counts in May 2023 and sentenced to life in prison.

The Daybells, who had a monthslong affair before getting married, were expected to be tried together last year, but 7th District Judge Steven Boyce severed their cases because of new DNA evidence.

In August 2019, Vallow Daybell moved to Rexburg, Idaho, from Arizona just months after her fourth husband was shot and killed. In the months that followed, her children went missing, and Tammy Daybell died in her home. Tammy’s death wasn’t initially investigated, but her body was exhumed two months later. Utah Chief Medical Examiner performed an autopsy and ruled her death a homicide.

Following a lengthy investigation, the Rexburg Police Department discovered the bodies of JJ and Tylee in June 2020. Tylee’s burned and dismembered remains and JJ’s bound body were buried in shallow graves on Chad Daybell’s eastern Idaho property.

Authorities have said they believe Vallow Daybell’s brother Alex Cox — who acted as her “protector” — killed or conspired to kill Tylee, JJ and Tammy Daybell, according to witness testimony. During both trials, evidence presented to the jury showed that Cox’s cellphone was on Chad Daybell’s property on the days the children were killed, and that he attempted to fire a gun at Tammy Daybell.

The jury didn’t have to prove Chad Daybell physically committed the killings to be convicted, Fremont County Prosecuting Attorney Lindsey Blake said during the prosecution’s closing arguments Wednesday. The jury must only believe he advised, assisted, encouraged, commanded or coerced someone to do it — someone like Cox.

“Alex does what Chad asks of him,” Blake said.

A member of The Church of Latter-day Saints, Daybell believed he received personal revelations from God that told him certain people — including Vallow Daybell’s children and Tammy Daybell — were possessed by dark spirits and would need to be “cast out,” or killed, according to witness testimony. The prosecution has accused the Daybells of using religion as a tool to manipulate others, including Cox, even saying in the indictment that they espoused religious beliefs “for the purpose of justifying” or encouraging the homicides.

“No one here is charged because of their religious beliefs,” Madison County Prosecuting Attorney Rob Wood said during Vallow Daybell’s trial. “They are charged for using those religious beliefs for the purpose of murder.”

Chad Daybell now faces the death penalty

Chad Daybell will now face an additional week or two of additional evidence where the same jurors, who have been sequestered, will decide whether he should be sentenced to death. That phase of the case began Thursday afternoon, and will continue Friday.

Lori Vallow Daybell didn’t face the death penalty after Boyce removed it as an option just before her 2023 trial in an unprecedented move. The decision came after prosecutors filed large volumes of evidence past deadlines, which could have impeded the defense’s ability to prepare for trial. Boyce said he wanted to make sure Vallow Daybell’s constitutional rights were protected.

University of Idaho Associate Professor of Law Samuel Newton told the Idaho Statesman in a phone interview that the death penalty phase typically takes a few weeks.

“You’re trying a person’s entire life, it usually takes a while,” he said.

It will be the defense’s job to humanize Chad Daybell during this portion of the case, Newton said, adding that they’ll likely bring in a mitigation specialist who will have investigated Daybell’s entire life looking into things like whether he had any mental health issues or generational trauma.

Throughout the trial, Daybell’s attorney John Prior argued that he was innocent, but now he’ll need to prove that Chad Daybell doesn’t deserve the death penalty, which Newton called a “conflated strategy.”

“These are just tough choices, that the defense has to figure out how they are going to do it,” Newton said, adding that it wouldn’t be uncommon if Daybell continues to proclaim his innocence.

The jurors were briefly brought back into the courtroom Thursday following the verdict where Boyce read several instructions to the jury and reminded them that to sentence Chad Daybell to death the prosecution must prove at least one aggravating factor. Under Idaho law, some of those factors could include:

“They’re going to look for his history of dangerous behavior or things that would indicate that he deserves the death penalty,” Newton said.

The jurors will be back at the Ada County Courthouse at 8:30 a.m. Friday.
