Lori Vallow Daybell: Timeline of ‘doomsday cult mom’ case

The case of Lori Vallow spans a deeply disturbing pattern of unexplained deaths, bizarre cult beliefs about killing zombies and murder

More than three years after her children were last seen alive, “doomsday cult mom” Lori Vallow is now behind bars staring down a life in prison.

Tylee Ryan, 16, and Joshua “JJ” Vallow, 8, vanished without a trace in September 2019, sparking a multi-state search while their mother appeared carefree – marrying her new husband Chad Daybell on a beach in Hawaii.

The children’s bodies were finally discovered nine months later buried in a pet cemetery on Mr Daybell’s property in Idaho. Their disappearances and deaths mark only part of a dramatic case that spans a deeply disturbing pattern of murders, unexplained deaths and bizarre cult beliefs about killing zombies.

On 12 May, the 49-year-old mother-of-three was found guilty of first-degree murder, conspiracy to commit first-degree murder and grand theft over the deaths of her two youngest children in Ada County Court in Boise, Idaho.

She was also found guilty of conspiracy to commit first-degree murder in the death of Mr Daybell’s first wife Tammy, 49.

Vallow was sentenced to life in prison without parole on 31 July.

But she is still awaiting trial in another case.

She is separately charged in Arizona with conspiring to murder her fourth husband Charles Vallow, with the help of her now-deceased brother Alex Cox – who mysteriously also died three months after the children’s disappearance.

She is also charged with conspiracy to murder her niece’s estranged husband Brandon Boudreaux after he narrowly escaped a drive-by shooting.

Here’s a timeline of the tragic and bizarre case:

1990 – Chad Daybell marries first wife Tammy Daybell and the couple found Spring Creek Book Company together in Utah. The company publishes Mr Daybell’s doomsday books. The couple have five children together and move to Salem, Idaho, in 2015.

1992 – Lori Vallow marries her first husband, high school sweetheart Nelson Yanes.

1995 – After divorcing Mr Yanes, Lori Vallow marries her second husband William Lagioia. The couple have a son, Colby, but divorce after around a year of marriage.

2001 – Lori Vallow marries for a third time. She and husband Joseph Ryan have a daughter, Tylee Ryan. The couple divorce in 2004.

2006 – Lori Vallow marries her fourth husband Charles Vallow. Colby and Tylee live with the couple while Vallow also has two children from a previous marriage.

2014 – Lori Vallow, Charles Vallow, Tylee and Colby move to Kauai, Hawaii, together. The same year, the couple adopts Joshua “JJ” Vallow. JJ is the biological grandson of Charles Vallow’s sister Kay Woodcock.

October 2018 – Chad Daybell and Lori Vallow finally meet in person for the first time at a religious conference in Utah.

February 2019 – Charles Vallow files for divorce saying he fears for the safety of himself and the children.

He had pleaded with authorities for mental health intervention for his wife but she was deemed competent at the time.

11 July 2019 – Charles Vallow is shot dead by Lori Vallow’s brother Alex Cox at Vallow’s home in Chandler, Arizona. Cox claims that he shot Vallow in self-defence when Vallow tried to attack him with a baseball bat. Police interviews show Lori Vallow smiling as she recounts what happened. Tylee – who was at the home at the time – gives a similar version of events as her mother that Cox acted in self-defence. Cox did not perform CPR and waited 43 minutes to call police.

September 2019 – Lori Vallow moves with JJ, Tylee and Alex Cox to Rexburg, Idaho, where Chad Daybell lives.

9 September 2019 – Alex Cox’s cellphone places him in the yard of Chad Daybell’s property for around two hours in the morning. Chad Daybell texts his wife Tammy Daybell to say that he has shot a raccoon and buried the animal in the pet cemetery on the grounds of the property.

22 September 2019 – JJ is last seen alive.
