Idaho prosecutors will seek the death penalty for Andrea Shaw, a young mother charged with murdering her twin toddlers, dramatically raising the stakes in a criminal case that has drawn national attention.
In a notice filed late last week in Idaho’s Third Judicial District Court, Payette County Deputy Prosecuting Attorney Ryon Sirucek identified four statutory aggravating factors that prosecutors intend to use to justify capital punishment if Shaw is convicted of first-degree murder.
Under a law that took effect in July 2026, firing squads are Idaho’s primary method of execution. The legislation followed a botched 2024 attempt to execute a 73-year-old man by lethal injection.
Prosecutors must prove at least one statutory aggravating circumstance before Shaw can be considered eligible for the death penalty. If Shaw is convicted, a jury would determine whether those circumstances exist.
According to the filing, prosecutors identified four aggravating circumstances: that Shaw allegedly committed two murders at the same time; that the murders were “especially heinous, atrocious, or cruel, manifesting exceptional depravity”; that she exhibited “utter disregard for human life”; and that her conduct demonstrates a propensity to commit murder that would make her a continuing threat to society.
Shaw was indicted by a grand jury and arrested on June 30 for allegedly deliberately suffocating her twins, who died on May 1, 2025. Prosecutors allege Shaw killed the children while they were sharing a bed. Her trial is scheduled to begin Jan. 11, 2027.
Shaw, who pleaded not guilty, has consistently denied the allegations. She suggested that her twins’ deaths may have been caused by the vaccines they received at a routine doctor’s appointment just over a week before they died.
According to court documents filed by her defense, Shaw took the twins to the emergency room on April 24, 2025, the day after they received routine vaccinations, because they were lethargic and their lips had turned blue.
The treating emergency room physician diagnosed both children with a “post-immunization reaction,” the filing states.
The children remained ill in the days leading up to their deaths, and Shaw repeatedly sought medical advice.
Neither the police nor the prosecution have publicly outlined the evidence they believe supports their claim that Shaw deliberately killed her toddlers. The grand jury indictment is sealed and not publicly available, and the coroner reports have not been released.
Shaw’s bail was initially set at $2 million. A district judge in Payette County, Idaho, later revoked the bail, which is discretionary in capital cases.
