Lori Vallow – the mother of the missing children Joshua “JJ” Vallow, 7, and Tylee Ryan, 17 – was arrested in Hawaii last week and is being held on a $5 million bond.

She's due back in court Wednesday in Kauai and is expected to contest her extradition to Idaho, where she was charged with two felony counts of desertion and nonsupport of dependent children, as well as resisting or obstructing police officers, criminal solicitation to commit a crime and contempt of court.

Despite skipping town in November, fleeing Idaho with her new and fifth husband, Chad Daybell, the author of several religious-themed novels about the end times, Vallow was not initially charged when she was finally located by Hawaii authorities in January. She roamed free – reportedly island-hopping in Maui – until she was finally arrested and charged last week. The children have been missing since September.

Three people connected with the couple have died under mysterious circumstances over the past year.  Just a month after her children went missing, and weeks after Chad’s former wife, Tammy Daybell, died unexpectedly in their Idaho home, Lori Vallow and Chad Daybell tied the knot in October.

Vallow’s former and fourth husband, Charles Vallow, accused her in divorce papers of joining a doomsday cult, declaring herself a godsent to prepare the world for an imminent apocalypse — before he met his own demise in July: Lori Vallow’s brother, Alex Cox, shot and killed him in their Arizona home, claiming self-defense. He was never arrested and he too then died unexpectedly in December.

Chad Daybell remains a free man in Hawaii and has not been charged in connection with the death of his former wife and mother of his five children. The deaths of Tammy Daybell, Charles Vallow and Alex Cox all remain under investigation. Autopsy reports have not been released.

Here’s a timeline of events in the case that’s captured national attention:

March 9, 1990: Chad and Tammy Daybell were married in Manti, Utah, her online obituary said. They founded Spring Creek Book Company, which allowed Chad to publish several religious-themed novels about the end times. They had five children and eventually moved to Salem, Idaho, in 2015.

April 3, 2018: Joseph Ryan, Tylee’s father and Lori Vallow’s third husband before their divorce, died. Police had performed a welfare check on his apartment after his neighbor’s dog detected a foul-smell. His death was ruled a heart attack and he was cremated. There is little information available about his death.

In an interview with Salt Lake City Utah’s KSL-TV, Joseph Ryan’s sister and Tylee’s aunt, Annie Cushing, said the last time she saw her ex-sister-in-law was in 2018. Lori Vallow had asked Cushing to come from out of state to support Tylee while she grieved the loss of her father. During her visit with Tylee, Cushing said her former sister-in-law seemed “unhinged” and questioned whether she was a “psychopath.”

LORI VALLOW RELATIVE KNOWS 'WHEREABOUTS' OF MISSING IDAHO KIDS BUT IS UNWILLING TO 'COOPERATE': REPORTS

Chad Daybell and Lori Vallow (pictured) appeared together for the first time on Preparing a People Podcast Network’s “Time to Warrior Up” in December 2018. They both discussed doomsday and theories about the end of the world. The podcast has since cut ties with the couple.

Lori Vallow and Joseph Ryan had married in 2000 but divorced four years later, when Tylee was just 18 months old, Cushing said. Tylee was Joseph’s first child, while Lori had an older son from a previous marriage, Colby Ryan, who took his stepfather's last name. They lived in Texas but Lori moved to Arizona after the divorce. Joseph moved there to be close to Tylee, as he and her mother remained locked in a contentious child custody suit, KSL-TV reported, citing court documents.

Colby Ryan’s biological dad is William Lagioia, Lori Vallow’s second husband, East Idaho News reported. Lori Vallow and Lagioia married in 1995 but divorced the next year, East Idaho News reported. Little is known about him. Lori Vallow’s first marriage, in 1992, also ended in divorce. The identity of her first husband is unknown.

Lori married her fourth husband, Charles Vallow, in 2006.

LORI VALLOW ABANDONED MISSING CHILDREN'S PHOTOS, BIKES, CLOTHING IN IDAHO STORAGE UNIT: REPORT

February 2019: Charles Vallow, Lori’s fourth husband, filed for divorce, claiming in court documents that he feared his wife would kill him and that she’d developed strange, doomsday-cultlike beliefs, reportedly calling herself “a god assigned to carry out the work of the 144,000 at Christ’s second coming in July 2020,” Fox 10 Phoenix reported.

That same month, Charles Vallow removed Lori from his $1 million life insurance policy, instead naming his sister and the grandmother of his adopted son JJ, Kay Woodcock, the sole beneficiary, East Idaho News reported.

July 11, 2019: Charles Vallow is shot dead inside an Arizona home by Lori’s brother, Alex Cox.

He was never arrested before his own death in December.

July 22, 2019: Lori Vallow sent Dog Training Elite in Phoenix an email about finding a new family for JJ’s service dog, Baily, due to a “change in life circumstances,” KTVB reported, citing court documents.

Late August-early September 2019: Lori Vallow moves to Idaho with her two children Tylee and JJ, renting a townhome at Rock Creek Hollow subdivision in the rural town of Rexburg, located in Madison County.

Sept. 8, 2019: Tylee was last seen on surveillance video at the entrance of Yellowstone National Park, which sprawls across Wyoming, Montana and Idaho. A photo from that day, later obtained by authorities from Lori Vallow’s iCloud account, showed Vallow, her brother Alex Cox, Tylee and JJ at the national park.

Sept. 17, 2019: The last known video of JJ was recorded. A doorbell camera captured footage showing JJ and another child playing outside at the Rock Creek Hollow subdivision. The video, first obtained by East Idaho News, showed JJ moving outside a doorframe, which activated the Ring Door camera, before running across the yard with another child.

Vallow reportedly told a child, who knocked on her townhome door later in the month looking for JJ, that her son had gone to Louisiana to spend time with his grandmother, KSL.com reported, citing court documents. Investigators determined that information was false – JJ’s grandmother was the one to report him missing in November.

Boudreaux and Pawlowski were locked in a child custody dispute. He alleged in court documents that his ex-wife had “knowledge of the whereabouts” of Tylee and JJ but was unwilling to cooperate with law enforcement. He also claimed Pawlowski had a “million dollars of reasons to have him killed,” as she was “hoping to cash in on the policy to help support the cult.” The court documents also stated Pawlowski sometimes told her ex-husband that “sometimes children are full of light and then just like that they go dark," Fox 10 Phoenix reported.
