**Nancy Guthrie Still Missing: Shocking New Twist – FBI Summons Mystery Woman After Chilling Discovery at the Scene**
(Exclusive Breaking Update – February 18, 2026 | Tucson, Arizona)
The nightmare surrounding the disappearance of 84-year-old Nancy Guthrie just took a razor-sharp, heart-stopping turn.
In the last few minutes, law enforcement sources have confirmed to multiple outlets: **the FBI has urgently summoned a woman for immediate questioning** after investigators uncovered a piece of evidence described as “highly significant” during a follow-up sweep of the crime scene or nearby area late yesterday.
The woman—whose identity remains shielded—is said to be someone **previously outside the main focus** of the investigation. She was not among the family, not among the previously detained individuals from the Friday night SWAT raid, and not linked to any prior tip. Yet something found at or near Nancy’s Catalina Foothills home was explosive enough to force authorities to pull her in without delay.
Details of the discovery are being tightly held. Sources would only say it is “physical evidence of substantial value” that could rewrite the narrative of what happened in the early hours of February 1, when a masked intruder deliberately blinded the doorbell camera at 1:47 a.m., Nancy’s pacemaker signal died at 2:28 a.m., and blood was left behind on the porch.
This bombshell lands amid a string of crushing disappointments:
– Friday’s massive federal raid ~2 miles away: SWAT teams, FBI, forensics vehicles everywhere. A gray Range Rover towed. Multiple people detained. Everyone released. No Nancy. No charges.
– The black glove breakthrough: DNA from the glove matching the suspect’s video gloves entered CODIS—only for the sheriff to announce yesterday: **no match** in the national database. Zero hits on known offenders.
– Helicopter Bluetooth scanners still circling, desperately hunting any whisper of a pacemaker signal. Nothing confirmed.
– Over 30,000 tips. $100,000 reward. Fake ransom hoaxes tormenting the family. But the real kidnapper? Utter silence.
Now the spotlight swings to this woman. Is she a witness who held back crucial information? Did she unknowingly encounter the intruder? Or—most disturbingly—does the new evidence place her closer to the night of the abduction than anyone imagined?
Pima County Sheriff Chris Nanos has not yet commented publicly on the summons, but insiders stress she is being treated as a **person of interest for information**, not formally a suspect at this hour. The FBI task force in Tucson is reportedly prioritizing her interview while forensic labs continue racing through evidence from the raid and the glove.
Savannah Guthrie’s pain remains raw. In her latest Instagram post yesterday she wrote:
“It’s been over two weeks since our mom was taken from us. We still believe she is alive. We still have hope. If you know anything—anything at all—please come forward. It’s never too late to do the right thing.”
Outside Nancy’s home, the memorial grows heavier by the hour: yellow flowers blanket the ground, ribbons tie every mailbox, the “Bring Her Home” banner is buried under fresh handwritten prayers. Neighbors say the entire community is holding its breath.
Time is cruel. Nancy’s heart condition means every day without her medications is a gamble with her life.
The next few hours could bring answers—or plunge this case into even deeper darkness.
Anyone with information is urged to contact the FBI tip line at 1-800-CALL-FBI or the Pima County Sheriff’s tip line immediately. The $100,000 reward remains active.
This is a rapidly developing story. We will update as soon as more is known.
What do you think this mystery woman knows?
Is this the break investigators have been praying for… or another cruel false hope?
