The Idaho Supreme Court will hear oral arguments in Lori Vallow-Daybell’s murder trial appeal later this fall.

The oral arguments will begin at 11:15 a.m. Nov. 2 at the Idaho Supreme Court Chambers, 451 W. State St. in Boise.

Vallow-Daybell filed her appeal last year, raising several issues from her murder trial through her attorney Craig H. Durham.

Vallow-Daybell was on trial for the murders of her two children, J.J. Vallow, 7, and Tylee Ryan, 16, in September 2019. The children were killed after Vallow-Daybell and her fifth husband and co-conspirator, Chad Daybell, came to believe they were “zombies” and needed to have their spirits freed from their bodies.

The couple’s affair began after they met in 2018 at a book convention. They later plotted to kill Vallow-Daybell’s husband, Charles Vallow, and Chad Daybell’s wife, Tammy Daybell, as well as Vallow-Daybell’s children.

J.J. Vallow’s body was found bound in duct tape and buried on Chad Daybell’s then-Salem property. Tylee’s burned and dismembered remains were found in a fire pit on the same property. Chad Daybell was also found guilty in the children’s murders, as well as for killing his first wife, Tammy Daybell, who was suffocated.

Vallow-Daybell was charged with three counts of conspiracy to commit first-degree murder involving her children and in the conspiracy to murder Tammy Daybell. She was additionally charged with one count of grand theft for continuing to accept Social Security money — an estimated $20,000 — intended for her deceased children from their late fathers.

In her appeal, Vallow-Daybell claims she was deprived of her Sixth Amendment right to counsel of her choice, involving her then-attorney Mark Means.

“This violated her fundamental Sixth Amendment right to counsel of her choice,” her appeal states.

In December 2021, Seventh District Court Judge Steven Boyce removed Means from the case, citing a conflict of interest between Means, Vallow-Daybell and Chad Daybell. Boyce later appointed Jim Archibald as Vallow-Daybell’s attorney.

The appeal also argues Vallow-Daybell was deprived of her Sixth Amendment right to counsel at a “critical stage” of the case. It alleges the state improperly “routed the disqualification issue into the companion case of State v. Chad Daybell,” which Vallow-Daybell claims prevented her counsel from intervening on her behalf.

A third complaint in the appeal alleges the court violated Vallow-Daybell’s 14th Amendment right to due process when it deemed her incompetent to stand trial. Vallow-Daybell spent several months at a mental health facility before her competency was restored.

“Her case was stayed, and she was not present,” her appeal states.

Another issue involves what Durham described as “wide-ranging uncharged ‘bad acts’ evidence at trial” that “injected prejudicial character and propensity evidence into the case.”

The final complaint alleges Vallow-Daybell didn’t receive a speedy trial. Weeks before the trial was set to begin, new evidence was introduced during discovery. Boyce declined to allow that evidence in order to preserve Vallow-Daybell’s right to a speedy trial — a decision that also took the death penalty off the table.

Vallow-Daybell is currently incarcerated at the Pocatello Women’s Correctional Center, where she is serving several life sentences. Her husband, Chad Daybell, is on death row while his case remains under appeal.

The Vallow-Daybell and Chad Daybell case brought worldwide attention to the Upper Valley, spanning from 2019 to 2024. Reporters descended on the community, and the case later inspired a Lifetime movie and several books.

Vallow-Daybell’s appeal hearing will be broadcast live from the Idaho Supreme Court chambers.
