In January, an American man named Colby Ryan posted a seven-minute video to YouTube addressing his mother, Lori Vallow.
“I want you to end this. I want you to end it for everybody, for the kids, for yourself, for all of us,” he said.
“I know you know [what] the right thing to do is and I know you have a good heart… It’s time to do the right thing.”
Lori and her new husband, Chad Daybell, fled in November 2019, the day after being questioned over the disappearance of Lori’s two youngest children: Joshua “JJ” Vallow, seven, and Tylee Ryan, 17.

The half-siblings were last seen in their Idaho town on September 23, but were never reported missing by the couple.
After three months on the run, Lori Vallow was arrested in Hawaii on February 20. Now, her husband Chad has been taken to jail after human remains were found in his Idaho home amid an investigation into the disappearance of his step-children.
Bizarre details of the case have gripped the US for months, from Lori and Chad’s doomsday beliefs to the deaths of their former partners and, most recently, Chad’s arrest.
This is what we know of the complicated case.
Lori’s strange beliefs.
In 2019, people close to Lori Vallow started to notice a change in her. She became infatuated with near-death experiences and spiritual visions and began spouting strange delusions about a second-coming of Christ. According to the Associated Press, she worked on a since-deleted podcast about the subject with Chad Daybell, who is the author of more than a dozen doomsday novels.
