BOISE, Idaho (AP) — Prosecutors say the mother charged in a triple murder case took part in a complex conspiracy that included unusual spiritual beliefs and efforts to kill those who stood in the way of her goals. Here, a look at the defendants and the first witnesses in the trial of Lori Vallow:

The defendant

Lori Vallow, 49, is a beautician by trade, a mother of three, and a wife — five times over. She’s pleaded not guilty to murder, conspiracy and grand theft charges in the deaths of her two youngest kids and her new husband’s previous wife.

Vallow’s first marriage, to a high school sweetheart when she was just 19, ended quickly. She married again in her early 20s, and had a son named Colby before divorcing. In 2001, Vallow married again, this time to a man named Joseph Ryan. The couple had a baby girl named Tylee in 2002, but divorced just a few years later. Ryan later died in his home of a suspected heart attack.

Charles Vallow, a member of The Church of Jesus Christ of Latter-day Saints, entered the picture several months later. Vallow joined the LDS church and the pair married in 2006. They later adopted Joshua Jaxon “JJ” Vallow.

But by 2019, that marriage had also soured. Charles Vallow filed for divorce, contending in court papers that Lori Vallow also believed herself to be a deity tasked with helping to usher in the biblical apocalypse.

The two were estranged but still married when Lori Vallow’s brother, Alex Cox, shot and killed Charles Vallow outside his Phoenix suburban home.

Cox told police the shooting was in self-defense and was never charged in the case. Shortly after Charles’ death, Lori moved to eastern Idaho with JJ, Tylee and her brother Cox.

Chad Daybell became her fifth husband on November 5, 2019 — roughly two weeks after his previous wife Tammy Daybell died under suspicious circumstances.

Meanwhile, JJ and Tylee were missing. They were last seen in September, and they were declared missing in November after extended family urged police to investigate. Their bodies were found the following year buried in Chad Daybell’s yard.

Chad Daybell

Daybell, 54, was also a member of the LDS church and a self-published author who wrote doomsday-focused fiction loosely based on church teachings. He married Tammy Daybell in 1990, and they had five kids.

Prosecutors say he met Vallow at a conference in Utah in 2018. The two purportedly felt an “instant connection” and claimed they had been married to each other in a past life, according to police records. Friends of the couple told investigators that the pair shared the same unusual beliefs, including that they could tell if someone had been taken over by an evil spirit.

Chad and Lori led a group of friends in trying to cast out the supposed evil spirits by praying and doing “energy work,” prosecutors said. Friends told police that in some cases they determined a person had become a “zombie,” fully controlled by the evil spirit. Vallow claimed the only way to get rid of a “zombie” was to destroy the person’s body, prosecutors say, and one friend told police she heard Vallow call the children zombies before they disappeared.

Tammy Daybell was initially described as having died in her sleep of natural causes. But an autopsy showed she was asphyxiated to death, prosecutor Lindsey Blake told jurors Monday.

Chad Daybell is also charged in the triple murder case. Like Vallow, he has pleaded not guilty to all the charges. He is expected to stand trial several months from now.

Colby Ryan

Ryan, 27, is Vallow’s only living child. Though he was born of Vallow’s second marriage, when his mother remarried Colby took Joe Ryan’s last name.

Colby Ryan, who testified that he had a happy childhood, started crying on the stand when prosecutors showed him photos of Tylee and JJ, and talked about how Tylee was receiving social security benefits because her biological father Joe Ryan died in 2018. Sometimes she would send money to Colby Ryan through a phone app, and sometimes his mom would put money into Tylee’s account to send to him, he said.

After Ryan moved out of the family home, he continued to exchange texts with Tylee. But shortly after what would have been Tylee’s 17th birthday in September 2019, the tone and syntax of those texts changed. Tylee had last been seen alive a few weeks earlier, but at the time Ryan didn’t know she was missing.

The occasional money transfers continued too, but through a different phone app under his mother’s name, he said.

After his siblings’ bodies were found, Ryan confronted his mother in an emotional recorded phone call that was played for jurors.

The call starts with Ryan asking Vallow if she thought she could keep hiding from him.

“I’m not hiding, why would you think I’m hiding?” she responds.

“Probably because you murdered my siblings! Maybe you should understand,” Ryan continued, before his mother interrupted:

“I didn’t. I’m sorry you feel that way,” she said.

Kay Woodcock

Woodcock is JJ’s grandmother, and she convinced Idaho police to check up on JJ after her normally regular phone calls and visits with the boy dried up. That “welfare check” in November 2019 revealed that both kids were missing. JJ’s father, Charles Vallow, is actually Woodcock’s brother: He adopted JJ as a baby because JJ’s biological parents — including Woodcock’s son — were unable to care for the child.

Woodcock was the first witness in the trial. She told jurors that JJ was born with some disabilities and was diagnosed with autism. After Charles died, Woodcock feared Vallow no longer wanted the boy. She was also worried that JJ may had witnessed his father’s death.

“We were so worried about JJ, and did he see what happened to his dad,” Woodcock told jurors.
