Nancy Guthrie Update Today: DNA Breakthrough, Walkie-Talkie Clue, and $1.1M Reward as Search Enters Day 33

The search for Nancy Guthrie, the 84-year-old mother of Today show co-anchor Savannah Guthrie, is now in its 33rd day with no arrest. Investigators are calling new DNA evidence the biggest development yet, while a retired FBI agent points to a walkie-talkie spotted on the suspect as proof of multiple kidnappers.

Nancy Guthrie Update: DNA Evidence Called the "Biggest News" in the Case

Retired FBI Special Agent Jennifer Coffindaffer described DNA recovered inside Guthrie's Tucson home as "the biggest news we have had recently," saying it "may truly be the perpetrator's."

Coffindaffer added that investigators are examining whether the DNA mixture belongs to the suspect or suspects, noting it is not Nancy's or her immediate family's.

Authorities are still facing challenges processing the mixed DNA, as the sheriff suggested it could contain genetic material from several people. Investigators are seeking to use investigative genetic genealogy in a bid to track down the suspect.

DNA from gloves found a few miles from the home did not match any entries in CODIS, the FBI's national database, though the gloves appeared to match those worn by the masked person captured in doorbell surveillance footage.

Walkie-Talkie Discovery Points to Multiple Suspects in Nancy Guthrie Kidnapping

Coffindaffer pointed to what appears to be a walkie-talkie visible in the pocket of the suspect seen on Nancy Guthrie's porch, which she believes indicates at least one accomplice was involved in the abduction.

Coffindaffer argued the device was not a WiFi jammer, since the suspect's presence did not interrupt the Nest camera signal or Nancy's pacemaker sync — which she says confirms a second person was communicating on the other end.

The retired agent also raised the possibility that two separate images of what authorities believed to be the same suspect on different days may actually show two accomplices dressed similarly, writing, "Porch Guy had help."

Sheriff Says Investigators Are "Definitely Closer" on Nancy Guthrie

Pima County Sheriff Chris Nanos told NBC News in an interview that aired on the Today show that investigators are "definitely closer," adding, "We've got a lot of intel, a lot of leads, but now it's time to just go to work."

Nanos also discussed digital forensics, confirming that cell tower data has helped eliminate certain individuals from the investigation, while acknowledging that a significant volume of that data still needs to be fully analyzed.

Approximately 10,000 hours of surveillance video are currently under review as part of the ongoing investigation.

Savannah Guthrie Family Visits Home, Offers $1.1M Reward

On March 2, Savannah Guthrie, her sister Annie Guthrie, and Annie's husband Tommaso Cioni visited a growing tribute of yellow flowers and cards left outside Nancy's home in Tucson to mark one month since her disappearance.

The family is offering a $1 million reward for information leading to Nancy's recovery, with Savannah Guthrie publicly stating it "can be paid in cash."

The FBI is separately offering up to $100,000 for information, while 88-CRIME is offering an additional $102,500, bringing the combined reward to more than $1.1 million.

Key Timeline in the Nancy Guthrie Disappearance

Nancy was last seen around 9:45 p.m. ET on January 31 when she was dropped off at her Catalina Foothills home north of Tucson after dinner with family. She was reported missing the following afternoon after failing to appear for an online church service with a friend.

At 2:28 a.m. on February 1, her pacemaker app stopped syncing with her iPhone — a detail investigators have treated as a critical timestamp in establishing when she was taken.

Since her disappearance, alleged ransom demands have been sent to multiple news outlets, including one described as involving cryptocurrency and containing graphic descriptions of consequences if the ransom is not paid.
