The investigation into the disappearance of Nancy Guthrie, the 84-year-old mother of NBC “Today” show co-host Savannah Guthrie, may hinge on forensic evidence still being analyzed in FBI laboratories, authorities say, as the case reaches its 100-day mark with no arrests and no public identification of a suspect.
Pima County Sheriff Chris Nanos, when confronted by FOX News Digital outside his department Saturday, offered a terse but telling response when asked if investigators were nearing a breakthrough. “We are,” he said, refusing to provide further details. It was the most direct acknowledgment yet that authorities believe momentum is building in a case that has captivated Tucson and drawn national attention.
The sheriff has developed a theory about the motive behind the crime but has not publicly disclosed it. No evidence has emerged to indicate whether Nancy Guthrie is still alive.
A Violent Abduction Captured on Camera
Nancy Guthrie was last seen on the evening of January 31, 2026, at her home near East Skyline Drive and North Campbell Avenue in Catalina Foothills, Arizona. She had shared dinner with her daughter Annie Guthrie, a poet married to AP biology teacher Tommaso Cioni. When Nancy Guthrie failed to join a virtual church service the next morning, February 1, friends raised the alarm. She was reported missing that day.
What detectives discovered inside painted a grim picture: blood droplets, her cellphone, and the heart medication she depends on daily. DNA belonging to an unknown person was also recovered from the home. Additional blood was located on the front steps. Authorities determined she had been forcibly removed.
Home security cameras provided investigators with critical visual evidence. A Ring Doorbell camera recorded video of a male intruder. A Nest camera captured a masked man on the doorstep who appeared to be carrying a holstered handgun and a stuffed backpack. The FBI subsequently released footage showing an armed suspect tampering with the front doorbell camera. Investigators have described the suspect as standing between 5 feet 9 and 5 feet 10 inches tall, with an average build, and carrying a 25-liter Ozark Trail Hiker Pack.
A key piece of evidence came from an unexpected source: Nancy Guthrie’s pacemaker lost its connection to her smartphone, providing investigators with a precise window for when she was likely abducted.
Mother’s Day Tribute as Search Continues
On Mother’s Day, Savannah Guthrie shared a montage of videos and photographs of her mother on Instagram, accompanied by an emotional message to mark the 100-day milestone.
“Mother, daughter, sister, Nonie — we miss you with every breath. We will never stop looking for you. We will not be at peace until we find you,” she wrote, before urging anyone with information to contact federal authorities at 1-800-CALL-FBI and reminding the public that tips can be submitted anonymously.
Nancy Guthrie’s three children — Savannah, Annie, and retired military colonel Camron Guthrie — have stood together publicly throughout the crisis. Savannah Guthrie is married to Mark Feldman; Annie to Cioni. The family has led a sustained public awareness effort that has reached from local communities to national media outlets.
Evidence Processing and Stalled Searches
Despite substantial digital and forensic evidence — including cell tower records, roadside surveillance footage, security camera recordings, and material undergoing laboratory testing — the investigation has produced no public updates for weeks. Volunteer search groups have ceased their efforts.
The Pima County Sheriff’s Department issued a statement this week aimed at reassuring a public eager for progress. “As we reach the 100-day mark in this investigation, scientific evidence processing and digital media analysis remain ongoing,” the office said, adding that detectives continue to pursue fresh leads and tips alongside the established evidence.
A reward exceeding $1.2 million has been assembled for information leading to a resolution — among the largest such rewards in any Arizona missing-persons investigation.
Sheriff Faces Political Pressure
The case has proceeded amid political turmoil surrounding Nanos. An attempt to remove the sheriff recently failed, though Pima County supervisors voted to send perjury allegations against him to the state attorney general’s office. Nanos has remained at the helm of the Guthrie investigation throughout the controversy, maintaining his priority is returning Nancy Guthrie home.
One hundred days after Nancy Guthrie’s abduction, the case remains unresolved — a sheriff claiming progress, a grieving family demanding answers, and a masked intruder whose face and name remain hidden.
