Lori Vallow Daybell has been handed two further life sentences after she was convicted of conspiring to kill her fourth husband and her niece's now ex-husband.

The so-called doomsday mom was found guilty of two counts of conspiracy to commit first-degree murder in two separate trials in Maricopa County.

Lori Vallow Daybell was sentenced to life in prison Friday on two murder conspiracy convictions in Arizona, marking an end to a winding legal saga for the mother with doomsday religious beliefs who claimed people in her life had been possessed by evil spirits.
