'Doomsday mom' Lori Vallow debuts her new look in prison mugshot as she is extradited from Idaho to Arizona to face murder charges over death of her fourth husband Charles and for plotting to shoot her niece's ex

'Doomsday mom' Lori Vallow has been captured in her latest prison mugshot following her extradition from Idaho to Arizona to face two murder charges.

She is accused of killing her fourth husband, Charles Vallow, and attempting to shoot her niece's ex-husband, Brandon Boudreaux, in 2019.

Vallow, 50, who was convicted of murdering her two children - seven-year-old JJ and 16-year-old Tylee - in 2019, sported a smirk in the image, with her dyed blonde hair fading. This marks the fourth mugshot of her this year.

After the extradition that lasted for 18 hours, Vallow was transferred from the Pocatello Women’s Prison to the woman's-only Estrella Jail in Phoenix after midnight, Thursday morning. 

She will be placed in isolation in a high-security area, Sheriff Paul Penzone said during a Thursday afternoon press conference. 

Penzone said: 'She is as much of a morbid threat to others as any other dangerous criminal we've had in our custody.'  

Deputies departed Maricopa County by vehicle on Monday, traveling to Pocatello, Idaho, to take custody Vallow due to air travel complications caused by weather. 

Vallow was 'very chatty' and 'sociable' along the way, according to officials driving with her, Penzone said. 

'On Nov. 30, deputies arrived back in Maricopa County just after midnight. Suspect Vallow was booked in the Maricopa County Sheriff's Office ITR facility. 

'This is one example of the exceptional, understated and efficient operations conducted by the Extraditions Detail of MCSO.

'The Maricopa County Attorney's Office will assume prosecution of the allegations. Pursuing criminals and bringing them to justice is what we do, and we're very good at it,' Penzone said. 

The extradition of Vallow occurred weeks after the body of her murdered son, JJ, was returned to his next of kin. JJ was discovered dead in June 2020. 

This past summer, Vallow was convicted of the killing of her two youngest children as well as conspiracy to murder her husband Chad Daybell's ex-wife Tammy Daybell.

She has since appealed her conviction, but also faces two cases in Arizona - one on a charge of conspiring with her brother to kill her fourth husband, Charles Vallow, and one of conspiring to kill her niece's ex-husband. 

Charles Vallow was shot and killed in 2019, but her niece's ex survived an attempt later that year.

The case began in July 2019, when Vallow's brother, Alex Cox, shot and killed her estranged husband, Charles Vallow, in a suburban Phoenix home.

Cox, who died later that year of what authorities determined were natural causes, told police he acted in self-defense.

Vallow was already in a relationship with Chad Daybell at the time, a self-published author who wrote doomsday-focused fiction loosely based on Mormon teachings. 

She moved to Idaho with her children and brother to be closer to him.

The young children were last seen alive in September 2019. Police discovered they were missing a month later after an extended family member became worried. 

Their bodies were found buried in Chad Daybell's yard the following summer.

Chad Daybell and Lori Vallow married in November 2019, about two weeks after Daybell's previous wife, Tammy, was killed.

Tammy Daybell initially was described as having died of natural causes, but an autopsy later showed she had been asphyxiated, authorities said.

Defense attorney Jim Archibald argued during the trial there was no evidence tying Vallow to the killings, but plenty showing she was a loving, protective mother whose life took a sharp turn when she met Chad Daybell and fell for his 'weird' apocalyptic religious claims.

Archibald suggested that Daybell and Vallow's brother, Alex Cox, were responsible for the deaths.

Daybell told her they had been married in several previous lives and she was a 'sexual goddess' who was supposed to help him save the world by gathering 144,000 followers so Jesus could return, Archibald said.

Vallow's former friend Melanie Gibb testified during the trial that Vallow believed people in her life had been taken over by evil spirits and turned into 'zombies,' including JJ and Tylee.

The family and the case was featured on the popular Netflix TV documentary, 'Sins of our Mother.'

Netflix's series, which features her surviving child Colby Ryan, 26, reveals the details behind the killings, and Lori's beliefs that convinced her there was a 'dark spirit' inside her daughter, and the only way to 'free the spirit is to kill the body.'

Chad Daybell, husband of Lori Vallow, was in court last month ahead of his own death penalty trial.

Daybell's trial is expected to begin next year and run for about two months.
