Nancy Guthrie Update: DNA Evidence Development Could Crack Case With New Technology
Today co-anchor Savannah Guthrie‘s mom, Nancy Guthrie, is still missing more than 10 weeks after she was abducted from her Tucson, Ariz., home-and in a new development involving DNA evidence, a sample from the 84-year-old's home has been sent to the FBI from a Florida lab.
On Thursday, April 16, ABC 7 reported that a private Florida lab working with the Pima County Sheriff's Department sent the DNA sample to the FBI within the past few days.
Reportedly, the FBI is using new technology for advanced analysis on the sample, in hopes of identifying the perpetrator in Nancy's kidnapping.
A Pima County Sheriff's Department spokesperson told Fox News Digital that the department has been "sharing a lot of things" with the FBI lab since the investigation into Nancy disappearance began.
Additionally, NewsNation Senior National Correspondent Brian Entin reported via X about the latest DNA evidence development. Entin shared that the sample "includes hairs found in Guthrie's home."

In February, Pima County Sheriff Chris Nanos said that DNA evidence from Nancy's home was "mixed," meaning it contained genetic material from more than one person.
"Our lab tells us that there are challenges with it," Nanos told NBC Nightly News of the Florida lab, per Fox News. "The technology is moving so fast and in such a frenzy that they think some of this stuff will resolve itself just in a matter of weeks, months, or maybe a year."
Nancy was last seen at her Catalina Foothills residence on the evening of Jan. 31. As of writing, no suspect has been named, despite Savannah offering a $1 million reward in exchange for information leading to her mother's recovery.
