More than seven weeks after 84-year-old Nancy Guthrie vanished from her home in an affluent Catalina Foothills neighborhood north of Tucson, authorities say they believe she was abducted in the middle of the night, but the high-profile investigation has yielded no arrests, no confirmed suspect in custody and no definitive trace of the mother of NBC "Today" show co-anchor Savannah Guthrie.

As of Wednesday, March 25, the search for Nancy Guthrie — who requires daily heart medication and relies on a pacemaker — remains active, with the Pima County Sheriff's Department, FBI and other agencies continuing to chase leads, analyze digital evidence and review surveillance footage from the surrounding area. Sheriff Chris Nanos has described the case as unusual, noting the family's full cooperation and clearing all immediate relatives of suspicion while emphasizing that Nancy Guthrie was "taken against her will."

Guthrie was last seen alive on the evening of Saturday, Jan. 31. She took an Uber to her daughter Annie Guthrie's home for dinner around 5:32 p.m., according to investigators. Family members dropped her off at her own residence around 9:30-9:45 p.m., and surveillance captured her garage door closing shortly after. She was expected to attend an online church service the next morning with friends but never appeared.

On Sunday, Feb. 1, when she failed to show up, family members grew concerned and reported her missing. Investigators quickly determined she had been removed from the home forcibly. Drops of blood confirmed to belong to Guthrie were found on the front porch. Her phone and critical medications were left behind, raising immediate alarms about her health.

Chilling doorbell camera footage recovered by the FBI showed a masked individual, believed to be a man of average build standing about 5-foot-9 to 5-foot-10, approaching the door armed with a gun around 1:47 a.m. on Feb. 1. The camera was then disconnected and removed. At approximately 2:28 a.m., the app connected to Guthrie's pacemaker disconnected from her phone, suggesting possible distress or removal from the area.

The FBI released images and a description of the suspect, increasing its reward to $100,000 for information leading to her location or an arrest. The Guthrie family later offered up to $1 million for information resulting in her safe recovery, stressing in emotional video pleas that they are "blowing on the embers of hope" while acknowledging the grim possibility she may not be alive.

Multiple purported ransom notes demanding millions — some referencing cryptocurrency — surfaced in the days and weeks after the disappearance, sent to media outlets and family members. Authorities have treated them cautiously, with at least one hoax note leading to charges against a California man. No proof of life has been provided, and investigators have not confirmed any payment or direct communication from a credible kidnapper.

The case has drawn intense national and international attention, in part because of Savannah Guthrie's prominence on morning television. The anchor has taken time away from the "Today" show to support her family in Tucson, posting pleas on social media and recently sharing a cryptic message of faith: "I believe." She and her siblings have visited the home, leaving flowers and joining in community vigils marked by yellow ribbons, crosses and signs reading "Let Nancy Come Home."

Pima County Sheriff Nanos has repeatedly praised the family's cooperation and explicitly cleared Savannah Guthrie, her sister Annie, brother Camron and their spouses of any involvement, calling suggestions otherwise "cruel." He has said the family are victims in this case.

Recent developments include a sharper focus on dates in the weeks leading up to the abduction. Authorities believe "something occurred" on Jan. 11, based on FBI analysis of digital equipment and footage, and are also examining activity around Jan. 24. Neighbors within a two-mile radius were asked to submit any doorbell or security camera video from those periods. FBI agents have returned to the neighborhood, questioning residents about possible internet disruptions or glitches that occurred on the night of the disappearance, potentially indicating tampering with connectivity.

Evidence collected includes gloves found near the scene (one set ruled out after linking to a local restaurant worker), possible DNA mixtures from the property that are undergoing complex forensic separation and analysis, and a backpack or other items under review. A person of interest was briefly detained in connection with a vehicle seen in the area but was released without charges. No arrests have been announced.

Forensic experts and law enforcement have described the abduction as potentially targeted, citing the secluded, vegetation-heavy property that could have allowed pre-surveillance or casing. Theories range from extortion plots exploiting the family's visibility to elder-related crimes, though Nanos has withheld specific motive details to protect the investigation's integrity. He has warned that the perpetrator "could absolutely strike again."

Nancy Guthrie, a widow since 1988, lived independently despite limited mobility and health issues. Her case has spotlighted vulnerabilities for elderly individuals aging in place, as well as the emotional toll of "ambiguous loss" on families when a loved one vanishes without answers. Experts note that while thousands of people go missing annually in the U.S., cases involving abduction of older adults with celebrity connections are rare and draw outsized scrutiny.

Search efforts have included ground and air sweeps of the rugged desert terrain around Tucson, coordination with federal agencies and thousands of public tips. The sheriff's department says the investigation remains active and will continue "until she is located or all leads have been exhausted."

Savannah Guthrie returned briefly to Studio 1A at Rockefeller Center to thank colleagues but remains focused on family and the search. In one video, she urged anyone with information — even seemingly minor details — to come forward anonymously via the FBI tip line at 1-800-CALL-FBI.

As the search enters its eighth week, the Guthrie family continues to plead for public help. "Someone knows how to find our mom and bring her home," Savannah Guthrie has said. Community support in Tucson remains strong, with vigils and ribbon campaigns, but the uncertainty weighs heavily.

Investigators stress that time is critical, given Guthrie's medical needs. No new major breaks have been publicly disclosed in recent days, but Nanos indicated in mid-March interviews that the team feels "definitely closer" on certain leads, including vehicle footage from a neighbor's Ring camera.

The disappearance has also prompted broader discussions about home security, the reliability of smart devices in crimes and the challenges of investigating cases with limited physical evidence but significant digital trails.

For now, Nancy Guthrie's whereabouts and condition remain unknown. The FBI and Pima County Sheriff's Department continue to ask the public for any information, no matter how small.

Anyone with tips is urged to contact the FBI at 1-800-CALL-FBI or submit anonymously online. The family reward is available consistent with FBI guidelines for recovery.
