Lori Vallow

Who were Lori Vallow Daybell and Chad Daybell, the so-called Doomsday Couple behind one of America's most disturbing true crime cases?

When Lori Vallow's children, sixteen-year-old Tylee Ryan and seven-year-old JJ Vallow, disappeared in 2019, the world watched in horror as the truth slowly began to emerge. What first appeared to be a missing children's case soon exposed a trail of death, deception, extreme beliefs, and devastating betrayal.

Lori was once seen as a devoted mother with a picture-perfect life. But behind the image was a web of lies that would lead investigators from Arizona to Idaho, and into the heart of a case involving missing children, suspicious deaths, religious extremism, and murder.

Her fifth husband, Chad Daybell, was a doomsday author with his own controversial beliefs. As the investigation deepened, questions grew around the sudden death of his wife, Tammy Daybell, and the disturbing connection between Chad, Lori, and the disappearance of Tylee and JJ.

This gripping true crime book examines the shocking evidence uncovered by police, the timeline of events, the deaths connected to the case, and the beliefs that appeared to bind Lori and Chad together. It looks at the disappearance of Tylee Ryan and JJ Vallow, the death of Tammy Daybell, and the wider circle of tragedy surrounding Lori's former husbands and family members.

Since this case first captured public attention, both Lori and Chad have faced justice. Lori Vallow Daybell was convicted in Idaho in 2023 in connection with the murders of her children and the conspiracy to murder Tammy Daybell. Chad Daybell was convicted in 2024 and sentenced to death for the murders of Tammy, Tylee, and JJ. Lori was also later convicted in Arizona in separate conspiracy cases connected to Charles Vallow and Brandon Boudreaux.

Part of this book follows the evidence as it unfolded in real time, while also considering the chilling question at the centre of the case: how did two people, bound by apocalyptic beliefs and personal ambition, become linked to so much death?
