Lori Vallow, the mother of two Idaho children that have been missing since September, has until Thursday evening to present the two children to the Idaho Department of Health and Welfare.
The 46-year-old mother, who police say now goes by Lori Vallow Daybell, was recently found in Hawaii with her new husband, Chad Daybell. Her estranged husband, Charles Vallow, was shot and killed by her brother last summer.
If Lori Vallow does not reveal the whereabouts of her missing children, 17-year-old Tylee Ryan and 7-year-old Joshua "JJ" Vallow, before the court-ordered deadline, she could be subject to civil or criminal contempt of court, ABC News reports.
"Do I think that she's going to bring them? Honestly, no," Joshua's grandfather Larry Woodcock told ABC News Thursday. "Nothing with Lori right now makes sense."
Neither Lori Vallow nor Daybell has been charged or arrested yet, Kaua'i police in Hawaii said Sunday.
"Child protection actions are normally confidential and sealed to protect the anonymity of the parties," officials with Idaho's Madison County and Rexburg police departments said in a statement. "The Madison County Prosecutor’s Office asked the Court for permission ... to alert the public and anyone with knowledge of the location or health and safety of the children."
Police say the couple initially lied to investigators about where the children were. When police returned to their home in Idaho to question them, the adults had disappeared.
Daybell's last wife, Tammy Daybell, died in October of what the family called “natural causes,” but police in Idaho have since exhumed her remains for further investigation. The findings of that investigation have not been released. Lori Vallow and Chad Daybell were married two weeks after Tammy Daybell's death.
In July of last year, Lori Vallow's former husband Charles Vallow, 62, traveled from Arizona to Texas to visit Lori Vallow and their children. But after he arrived to pick up his son, he and Lori Vallow started arguing.
Lori Vallow's brother, Alex Cox, intervened and killed Charles Vallow, police said at the time. On Dec. 12, Cox died. Police were awaiting autopsy results to determine the cause of death.
The children lived, at least for a time, in Arizona. And, when initially questioned about Joshua's whereabouts, Rexburg police were told he was staying with a family friend in Arizona, which ended up being false, police said.
On Dec. 20, the Rexburg Police Department, posted on Facebook that it, along with the Fremont County (Idaho) Sheriff's Office and the assistance of the FBI, was investigating possible ties between the two missing children and the death of a Fremont County woman.
The woman was Tammy Daybell, was Chad Daybell's previous wife, who died in her home at age 49.
On Nov. 26, Rexburg police tried to do a welfare check on Joshua, who is adopted and has special needs, at Lori Vallow's home. Family from outside Idaho had not been able to speak to Joshua since September and were concerned, police said.
On Nov. 27, Rexburg police searched locations associated with Lori Vallow in an attempt to find Joshua. During these searches, investigators discovered Lori Vallow and Chad Daybell had "abruptly vacated" their home and left town, police said.
Joshua did not appear to be with them, police said. He last attended school in Rexburg on Sept. 23. Tylee Ryan also has not been seen or heard from since September, police said. Investigators contacted extended family members, none of whom had been in contact with the children since September. The children had not been reported missing.
Friends and family members have spoken out in the media with their concerns over Lori Vallow and Chad Daybell's religious beliefs and focus on the end of the world.
A Facebook post by Kay Woodcock, Joshua's grandmother, says Lori Vallow was a "wonderful, loving, attentive mother" until things started changing in the past 18 months because of her involvement with a new religious group, which Woodcock called a "cult."
Chad Daybell, who says on his website that he is a Latter-day Saint, has written and self-published more than 25 books, some of which focus on near-death experiences, including Daybell's own. Other books fictionalize the end of the world.
Both Daybell and Vallow were involved in an organization called "Preparing A People," which has said it is "not a 'group' and is not a 'Cult' or something people join" in a posted statement on its website.
