Lori Vallow’s Life Sentence: How the ‘Doomsday Mom’ Case Ended in Three Victims’ Deaths

Lori Vallow Daybell once appeared to be an ordinary mother raising her children. But a series of disappearances, suspicious deaths and disturbing religious beliefs eventually turned her into the central figure in one of America’s most notorious criminal cases.

In July 2023, Vallow was sentenced to life in prison without the possibility of parole for the murders of her two youngest children and conspiracy to murder her husband’s first wife. Her case later took another turn when she was convicted of additional murder-conspiracy charges in Arizona.

The investigation began in 2019, when Vallow’s children, 16-year-old Tylee Ryan and seven-year-old Joshua “J.J.” Vallow, disappeared in Idaho. Their relatives grew increasingly concerned after Vallow and her new husband, Chad Daybell, gave conflicting explanations about the children’s whereabouts.

Authorities eventually discovered the children’s remains buried on Daybell’s property in June 2020. The discovery transformed a missing-person investigation into a murder case that attracted national attention.

Prosecutors argued that Vallow and Daybell had embraced extreme apocalyptic religious beliefs, including the idea that certain people had become possessed by evil spirits. Witnesses testified that the couple used these beliefs to justify their actions against people they considered spiritually dark.

The investigation also examined the death of Tammy Daybell, Chad’s first wife, who died in October 2019. Her death was initially considered natural, but investigators later concluded that she had been murdered.

In May 2023, an Idaho jury found Vallow guilty of first-degree murder in the deaths of Tylee and J.J., as well as conspiracy to commit murder in Tammy’s death. She was also convicted of grand theft related to Social Security benefits intended for her children.

At her sentencing hearing on July 31, 2023, the judge imposed life imprisonment without the possibility of parole on the murder and conspiracy convictions. Vallow continued to maintain that the case had been misunderstood and denied that the victims had been murdered.

Her legal troubles did not end with the Idaho case.

In April 2025, an Arizona jury found Vallow guilty of conspiring to murder her estranged husband, Charles Vallow, who was fatally shot by her brother, Alex Cox, in 2019. She was also convicted of conspiring to murder her niece’s former husband, Brandon Boudreaux, who survived a shooting later that year.

In July 2025, Vallow received two additional life sentences for those Arizona convictions.

Meanwhile, Chad Daybell was convicted in Idaho in 2024 of murdering Tylee, J.J. and Tammy. He was sentenced to death.

The case has continued to raise questions about how extreme beliefs, family relationships and a series of suspicious events intersected before authorities uncovered the full extent of the crimes.

For the victims’ surviving relatives, the verdicts brought legal accountability after years of uncertainty and grief. But the loss of two children and the other victims remains at the heart of a case that shocked the country.
