Lori Vallow Daybell is an American woman who gained international notoriety after being convicted in a “doomsday”-themed murder case. She was found guilty in May 2023 of murdering her two children — 16-year-old Tylee Ryan and 7-year-old Joshua “JJ” Vallow — and conspiring to kill her husband’s first wife, Tammy Daybell. Lori and her fifth husband, Chad Daybell, shared radical apocalyptic religious beliefs, which prosecutors say they used to justify the killings.
In July 2023, she was sentenced to three consecutive life terms without parole. She later faced and was convicted of additional conspiracy charges in Arizona related to the deaths of her former husband Charles Vallow and others.
