Lori Vallow Daybell, Idaho mother accused of killing her children and conspiring to kill husband's first wife, was motivated by 'money, power and sex,' prosecutors say

An Idaho mother who is accused of killing her two children and conspiring to kill her husband's first wife was motivated by "money, power and sex," prosecutors said as opening statements in her trial began Monday, according to CNN affiliate East Idaho News.

Lori Vallow Daybell is charged with two counts of first-degree murder and three counts of conspiracy in the deaths as well as grand theft for collecting government benefits on behalf of her children after they were killed, the indictment states.

She has pleaded not guilty to all charges. Jury selection took place last week.

Fremont County Prosecutor Lindsey Blake told the jury on Monday that Vallow Daybell "used money, power, and sex to get what she wanted. It didn't matter what it was," East Idaho News reported.

The sensational case, featured in a Netflix true-crime documentary last year, involves the deaths of a number of family members and claims Vallow Daybell and her husband had apocalyptic religious beliefs.

Two of Vallow Daybell's children from previous marriages, Tylee Ryan, 17, and Joshua "JJ" Vallow, 7, were last seen on different days in September 2019. Shortly after that, she married Chad Daybell, whose first wife Tammy Daybell had died several weeks prior.

"The defendant will remove any obstacle in her way to get what she wants - and she wanted Chad Daybell," Blake said, according to East Idaho News.
