Investigators have fresh hope that the new DNA technology will help to solve Nancy Guthrie's mysterious disappearance.
Nancy Guthrie's disappearance has left the country curious for three months now. And the lack of a breakthrough has left everyone confused. But a hope has emerged after days, which might just solve the case. For those unaware, multiple DNA evidence has been found during the search for the 84-year-old. Although the regular search failed to find answers, investigators are looking to advanced forensic science and New DNA technology to test that key evidence and generate more leads. As optimism looms over this new technology, let's know more about it.
According to reports from multiple outlets, including NewsNation and Fox News, investigators have sent key DNA samples to the Federal Bureau of Investigation for advanced testing. It also includes a hair strand found from the crime scene, i.e., Nancy Guthrie's Tucson home. Genetic genealogist Cece Moore explained that new methods, such as whole genome sequencing, can extract usable DNA from hair without a root, which was not possible with older methods. Sharing her hope for the new technology, Cece said:
"I am pretty confident that they will want to use the lab that they have been extremely successful with, which is Astrea. DLI has been working to refine their own rootless hair analysis, but I haven't seen any successful cases from them yet."
Cece explained that the possibility of a breakthrough through the method is high. At the same time, the expert noted that labs such as Astrea have already shown success in similar cases. She pointed out that despite the novelty of this technology, which only came into use in 2018, new techniques have taken it further. So, they helped solve high-profile cases such as the Gigi Beach serial killer case. On the other hand, former CIA officer and FBI agent Tracy Walder emphasised that forensic evidence is significant in the case given the lack of digital or video evidence. Tracy believes that DNA could eliminate suspects in the case.
Until now, the DNA evidence in Nancy Guthrie's case has been complex, and no breakthrough has been made. Authorities confirmed that the blood found at the crime scene belongs to Nancy. So, there might have been a possible struggle in the case. Investigators also found a black glove worn by a masked man seen in the doorbell footage of Nancy's home. However, it has not yet been matched to any profiles in national databases such as CODIS. At the same time, forensic teams have found mixed DNA from multiple people at the home.
Even a hair sample found at Nancy Guthrie's home is under advanced testing. It is considered one of the most important pieces of evidence because it could give a usable genetic profile. Pima County Sheriff, Chris Nanos has accepted that previous testing did not give a suspect. It is the key reason why they are using a newer technology now. In her words:
"We need this information to be able to rule people out or rule people in, in this case. So, in a case like this, where we really actually don't have a lot of digital forensic evidence, which obviously the FBI is very good at, really, this becomes very, very important."
Nancy Guthrie's case dates back to February 1, 2025, when the 84-year-old went missing from her home in Tucson, Arizona. She is the mother of Savannah Guthrie, and was last seen the night before she went missing. The next day, her family reported her missing when she did not go to her regular church service. Authorities believe that she may have been targeted and possibly taken forcibly from her home. Meanwhile, after months of investigation, the police and the FBI have found evidence or a clear motive in the case. At the same time, no digital evidence, such as phone or surveillance data, has been found.
