EXCLUSIVE: A trial lawyer and former prosecutor believes investigators in the Nancy Guthrie case will still be protecting key evidence as he reveals the moves he'd make in trying to solve the case18:30, 31 Jul 2026Updated 18:34, 31 Jul 2026Nancy Guthrie remains missing, but a high-profile attorney still holds hope that the case can be solved. Thursday marked six months since the mum of US TV anchor Savannah Guthrie disappeared from her home in Tucson, Arizona, on January 31.Savannah continues to hold out hope for her 84-year-old mum's return, and recently made yet another plea to any alleged kidnappers. The Today Show host took to Instagram to plead directly to anyone involved in her mum's disappearance.Within her video post, she said: "I am coming on today with a very specific message," as she opened her statement. "It has been months since our mom was taken from us. Our family is in agony. We are in a nightmare that will not end. Nothing about our situation has changed. We have done our part. We will never stop looking for her."She added: "So I'm asking you, begging you, to do the right thing now. Make the right choice. Help us find her. Tell us where to look for her. I truly believe it is never too late to do the right thing. Help us bring this situation to an end."But while these cries for help remain emotionally intense, Bobby Taghavi, a trial lawyer and former prosecutor who served as a key member of the elite task force that investigated and prosecuted the notorious Golden State Killer, Joseph James DeAngelo, believes these have been carefully orchestrated.Speaking exclusively to the Mirror on the six-month anniversary of Nancy's disappearance, Taghavi said of Savannah's public pleas: "Public appeals in high-profile cases are usually made with careful consideration because every statement has the potential to generate new leads or encourage someone with information to come forward."He added: "Public attention is a double-edged sword. It generates valuable tips and keeps the case alive, but it also creates misinformation, speculation, and false leads that investigators have to carefully sort through."Taghavi, who is Managing Partner at Sweet James, admitted that such a case is difficult due to the little direct evidence available to identify any suspect. He told us: "If I were working the investigation, I’d keep rebuilding the timeline, re-examining the physical evidence with today’s technology, and never assume every lead has already been exhausted."Speaking of the alleged ransom notes that have come in during the investigation, he added: "Every ransom communication has to be taken seriously until proven otherwise, but high-profile cases often attract hoaxes. Investigators will focus on whether the sender knew details only the perpetrator would know and whether the communication can be independently verified."But he admits he believes investigators will be withholding specific information about the case. While testing on the hair found at the home of Nancy is complete and reportedly does not point to a suspect in her kidnapping, according to the sheriff's office, Taghavi said he thinks investigators will be "still protecting key evidence".Officers are continuing their investigation. Nancy's condition remains unknown.Article continues belowLike this story?
