Andrea Shaw, a 23-year-old mother from Payette, Idaho, has been indicted on two counts of first-degree murder in connection with the deaths of her 18-month-old twins, Tyson and Dallas. The toddlers were found deceased in a shared bed on May 1, 2025, prompting a homicide investigation by local authorities.

Police responded to a report of a possibly deceased child and discovered the twins upon arrival. The Ada County medical examiner’s office was tasked with determining the cause of death while the investigation remained ongoing.

Days after the twins' deaths, Shaw and her husband appeared on a podcast produced by the anti-vaccination group Children’s Health Defense, formerly led by Robert F. Kennedy Jr., where Shaw claimed that vaccines had caused her children’s deaths. The family also launched a GiveSendGo fundraiser stating the twins had received routine vaccines at their 18-month well-child visit and died in their sleep a few days later.

Shaw has said she was considered a suspect and was informed during interrogation that the cause of death was determined to be asphyxiation rather than medical causes. A family member, Filicetti, expressed belief in the vaccine-related cause, citing medical experts who examine complications.

Payette police have stated that, as the case is now before the court, they will not comment further on the facts or evidence, with future updates expected through judicial proceedings.
