The couple’s indictment came nearly a year after investigators found the remains of Ms. Vallow’s children Tylee Ryan, 17, and Joshua Vallow, 7, last June, buried at the home of Mr. Daybell, who was their stepfather.
Prosecutors did not say how the children had been killed, but the couple’s religious beliefs played a role, according to the indictment. Mr. Daybell and Ms. Vallow “did endorse and teach religious beliefs for the purpose of justifying” the murders, the indictment said.
Mr. Daybell’s previous wife, Tammy Daybell, 49, was found dead in October 2019 in her home in Idaho. Her death was initially attributed to natural causes, but the authorities ordered that her remains be exhumed, suspecting that her death might have been connected to Ms. Vallow’s missing children.
According to the indictment, Mr. Daybell and Ms. Vallow said in a text message exchange that Ms. Daybell had been in “limbo” and was “being possessed by a spirit named Viola.” Mr. Daybell had increased the amount of coverage in a life insurance policy for Ms. Daybell in September 2019, a little more than a month before her death.
