Sergey Torop, who leads a community of thousands in the woods of Siberia, was arrested in a major security operation.

The new felony charges against Lori Vallow Daybell came late Monday, the latest twist in a case tied to the mysterious deaths of the couple’s former spouses and their beliefs about zombies and the apocalypse that may have affected their actions.

Police discovered the remains of 17-year-old Tylee Ryan and her 7-year-old brother, Joshua “JJ” Vallow, at a property belonging to their mother’s new husband.

Authorities have not released the identities of the bodies discovered on the property of Chad Daybell, who married the children’s mother, Lori Vallow Daybell, a few weeks after the kids were last seen.

Chad and Lori Daybell are accused of lying about the whereabouts of Lori Daybell's two missing children, seven-year-old Joshua “JJ” Vallow and 17-year-old Tylee Ryan, and are also under scrutiny following the deaths of both of their former spouses.

The tangled case against Lori Vallow includes investigations into the deaths of her brother, ex-husband and new husband’s ex.

Several former members of the secretive group have spoken to the media, alleging it encourages girls to get married as young as 14 and provides little proper education.

The tangled case spans multiple states and includes investigations into three separate deaths surrounding the mother, Lori Vallow.

The patriarch of the family — a former member of the so-called "Moonies cult" — has been charged in connection with the case.

Former followers accused the Grace Road Church founder of "thrashing" them to drive out evil spirits before doomsday.
