Boise (Idaho), Jun 1 (AP) Chad Daybell has been sentenced to death for the murders of his wife and his girlfriend's two youngest children in Idaho.

The sentence was handed down Saturday after an Idaho jury unanimously agreed that imposing the death penalty would be a just resolution to the triple-murder case. The sentence marks the end of a grim investigation that began with a search for two missing children in 2019. The next year their bodies were found buried in Daybell's eastern Idaho yard.

Both Daybell and his new wife, Lori Vallow Daybell, were charged with multiple counts of murder, conspiracy and grand theft in connection with the deaths of Vallow Daybell's two youngest children, 7-year-old Joshua “JJ” Vallow and 16-year-old Tylee Ryan. They were also charged with conspiracy and murder for the death of Daybell's first wife, Tammy Daybell.

During a nearly two-month-long trial, prosecutors said Chad Daybell promoted unusual spiritual beliefs including apocalyptic prophecies and tales of possession by evil spirits in order to justify the killings.

Daybell's defence attorney John Prior argued during the trial that there wasn't enough evidence to tie Daybell to the killings, and suggested Vallow Daybell's older brother, Alex Cox, was the culprit. Cox died in late 2019 and was never charged, and Vallow Daybell was convicted last year and sentenced to life in prison without parole.

During the sentencing hearing, Prior asked the jurors to judge Daybell on his life before he met Vallow Daybell, describing her as a bomb that blew him off the trajectory of an otherwise wholesome life. But Daybell also declined to offer any mitigating evidence during the sentencing hearing. Mitigating evidence is often used to encourage jurors to have sympathy for a defendant in an effort to show that a life sentence would be more appropriate than capital punishment.

Family members of the victims gave emotional statements to the jurors. JJ Vallow's grandmother Kay Woodcock tearfully described how the 7-year-old would show empathy and compassion to others through soft touches and by frequently asking if those around him were OK. She also said Tylee was a doting big sister, and that it warmed her heart to see them together.

“I can't express just how much I wish for more time to create memories,” Woodcock said, beginning to weep.

Idaho law allows for execution by lethal injection or firing squad, though firing squad executions have never been used in the state. (AP)
