So-called “Doomsday Mom” Lori Vallow Daybell is seeking a new trial less than two weeks after a jury found her guilty of conspiring to kill her fourth husband, Charles Vallow.

In the newly released court documents, Vallow Daybell is claiming Juror 15 shared in a local television interview that they were aware of her prior murder convictions in Idaho despite them not being brought up at trial.

During the juror interview after the trial, Vallow Daybell, who represented herself, said Juror 15 reacted to learning about her prior convictions with the response, “You know, I feel sorry for her. Driving home yesterday, I was like, ‘God she’s spending the next three lives in prison in a cell …’” court documents said.

Vallow Daybell and Chad Daybell were convicted of the 2019 murders of two of Vallow’s children, 7-year-old Joshua “JJ” Vallow and 16-year-old Tylee Ryan. The couple, who believed some people had dark spirits and shared apocalyptic religious beliefs, were also convicted of murdering Chad Daybell’s first wife, Tammy Daybell. They were sentenced to life in prison. 

“All of these comments add up to prosecutorial misconduct.”

Vallow Daybell is scheduled to go on trial in Phoenix in May for an alleged plot to kill her niece’s ex-husband after a judge denied her motion to dismiss the case.

She previously explained to True Crime Arizona that she had been “working on her case for five years” and knows it “better than an attorney can learn it in two years” after making the decision to represent herself.
