New expert analysis is adding a troubling dimension to the investigation into Nancy Guthrie’s disappearance. A former FBI agent believes the crime may have involved weeks of surveillance rather than a spontaneous act. While authorities have not confirmed those claims, the theory has intensified public concern about how carefully the incident may have been planned.
Nancy Guthrie’s kidnapper had been to the house before, says ex-FBI agent
Crime expert Tracy Walder, a former CIA officer and FBI special agent, has suggested the person responsible for Nancy Guthrie’s kidnapping may have stalked her for a while before the incident occurred. Speaking to NewsNation, Walder emphasized that her assessment is based on publicly available investigative details.
“I believe that this was obviously very targeted,” the ex-FBI agent claimed. She added that, in her opinion, the suspect had likely visited the property prior to the abduction. She claimed the individual may have spent “at least for a month or so” observing the household’s “pattern of life” before choosing when to act.
Her comments follow confusion surrounding the FBI’s release of a new image of a person of interest without clarification about when the photo was taken. Walder speculated that the picture could show the same individual during an earlier visit, possibly while surveying the property rather than committing the crime.
Authorities had previously asked neighbors to submit Ring doorbell footage from weeks before Nancy Guthrie disappeared. This has fueled theories that investigators suspect repeated visits to the area.
Surveillance footage shows an armed, masked figure outside Guthrie’s Arizona home. Investigators allege the person attempted to obscure a doorbell camera. Walder noted that while the method appeared unsophisticated, it did not rule out careful planning.
Meanwhile, forensic evidence recovered from inside the home has added another layer of complexity. Officials have said that DNA collected at the scene is “mixed,” meaning it contains genetic material from multiple people. Experts warn that such a sample could significantly slow identification efforts.
Nancy Guthrie, 84, went missing on February 1. Authorities continue to urge anyone with information or surveillance footage to come forward as the investigation remains ongoing.
