Three months after Nancy Guthrie vanished from her Arizona home, investigators are still searching for answers in one of the most closely watched missing person cases in the country. Now, attention has turned to a single piece of DNA evidence that officials believe could become a major breakthrough. As forensic testing continues, the disappearance of Savannah Guthrie’s mother remains an active investigation with no public resolution yet.
The case has drawn nationwide attention, especially as investigators continue reviewing surveillance footage, blood evidence, and thousands of public tips.
Nancy Guthrie, the 84-year-old mother of Today show host Savannah Guthrie, was reported missing on February 1. Homicide detectives were eventually brought into the investigation as officials worked alongside local agencies, including Border Patrol, to search for clues.

What makes the DNA sample so important?
One of the biggest developments in the investigation centers around DNA evidence recovered during the early stages of the case. Authorities confirmed that the sample did not belong to Nancy Guthrie, immediately raising questions about who may have been inside the home around the time she disappeared.
The DNA evidence was reportedly sent from Tucson to a specialized laboratory in Florida for further examination. Federal authorities are now involved in the testing process as investigators continue to wait for results.
Retired FBI special agent Jason Pack explained to CBS News that forensic testing is rarely quick or simple, despite how it is often portrayed on television.
According to Pack, scientists first have to eliminate DNA belonging to relatives, close contacts, or people who regularly visited the home before narrowing down any unfamiliar profile that could become significant in the investigation.
Former FBI special agent Lance Leising also stressed how important the location of the evidence could become.
"An item containing DNA, such as a strand of hair found somewhere in a house, is one thing, but a strand of hair near the victim's last known location, such as in her bed, would be a high priority for the FBI," he explained.
Authorities, however, have not publicly disclosed exactly where inside the home the unidentified DNA was recovered.
Why has the investigation slowed down?
As weeks turned into months, criticism surrounding the investigation began to grow. The Pima County Sheriff’s Department faced questions over delays tied to DNA processing and other forensic procedures. Sheriff Chris Nanos eventually stopped discussing specific evidence publicly, saying revealing too much could damage the integrity of the case.
"It would be highly inappropriate of me to speak to the evidence. We have to keep the integrity of this case," he stated.
"If we make an arrest, that individual has the right to a fair trial, I can't sit here and address all of that."
Investigators have also continued examining surveillance footage gathered from the property and surrounding area. Doorbell camera video reportedly captured suspicious activity connected to the disappearance.
Blood spatters were also reportedly found near Nancy’s front porch step, further deepening investigators’ concerns that the case involved an abduction rather than a voluntary disappearance.
Could forensic testing finally reveal answers?
Authorities’ suspicions appeared to intensify after alleged ransom notes connected to Nancy Guthrie surfaced publicly. Reports indicated the Guthrie family initially considered complying with the demands, but no money was ultimately exchanged and Nancy was never returned.
According to her family, she depended on vital medication to survive, leading loved ones to fear the worst as the investigation passed the 100-day mark. Despite the growing frustration surrounding the lack of answers, officials insist the case remains active. Detectives continue reviewing evidence while waiting for forensic testing results that could potentially identify a suspect or confirm how Nancy disappeared.
Investigators appear to believe that the unidentified DNA sample may become the most important clue in the entire case. And after 100 days without answers, that single piece of evidence could determine whether the mystery surrounding Nancy Guthrie’s disappearance is finally solved.
