Closing arguments begin in "doomsday mom" Lori Vallow Daybell's murder trial

Closing arguments in the trial of Lori Vallow Daybell, charged with murder in the deaths of her two children and conspiracy to commit murder in the death of her husband's first wife, began Thursday as her weekslong trial in Boise, Idaho, draws to a close.

Vallow Daybell, who did not take the stand in her own defense, is accused of murdering two of her children, 16-year-old Tylee Ryan and 7-year-old Joshua "JJ" Vallow, who were last seen in September 2019. Vallow Daybell married her current husband, Chad Daybell, in November, just two weeks after the death of Daybell's first wife, Tammy.

Prosecutors say the couple used "doomsday" beliefs involving zombies to justify murdering the children and Tammy Daybell.
