Lori Vallow Daybell, an Idaho mother, has been sentenced to life in prison without the possibility of parole, the maximum sentence, for the gruesome killings of her two youngest children, Joshua "JJ" Vallow, 7, and Tylee Ryan, 16, as well as the conspiracy to commit murder of her husband's former wife, Tammy Daybell. The bodies of JJ and Tylee were discovered more than three years ago in her husband's backyard in rural eastern Idaho.
