As the search for 84-year-old Nancy Guthrie enters its fourth week with no suspects named and no confirmed leads, the family of TODAY co-anchor Savannah Guthrie escalated the public appeal on Monday with a $1 million reward announcement — while new reporting raised the possibility that her abductor had cased her Tucson home days before the February 1 disappearance.

Savannah Guthrie Announces $1 Million Reward, Acknowledges Mother May Be Dead

In an emotional video posted to Instagram, Savannah Guthrie announced that the family is offering up to $1 million for information leading to her mother's recovery. According to the post, the reward is not contingent on an arrest, can be split among multiple valid claimants, and has been coordinated with the FBI. The announcement marked the most significant public escalation by the family since Nancy Guthrie's disappearance.

In the same video, Savannah made her most direct acknowledgment yet that her mother may not be found alive. "We also know that she may be lost, she may already be gone," she said — the first time a family member has publicly allowed for the possibility of Nancy's death.

Alongside the reward announcement, the Guthrie family also announced a $500,000 donation to the National Center for Missing & Exploited Children, according to multiple outlets covering the announcement.

New Reports Suggest Suspect May Have Scouted the Home in Advance

A significant new development emerged Monday when multiple outlets — including ABC News, CNN, Fox News, and NewsNation — reported from sources that a doorbell camera image previously released by the FBI showing the suspect without a backpack was captured on a different day prior to February 1. This would suggest the suspect visited Nancy Guthrie's Catalina Foothills home at least once before the morning of her abduction.

One theory circulating among sources, as reported by those outlets, is that the suspect may have been startled by the doorbell camera on the earlier visit and returned later — possibly to tamper with it — before carrying out the abduction. Sources declined to specify the exact date of the earlier visit. The FBI and the Pima County Sheriff's Department both declined to comment on the reports, with PCSD characterizing the scouting theory as "purely speculative."

If accurate, the detail would represent a meaningful shift in understanding the case — suggesting a degree of planning or premeditation rather than an opportunistic crime.

Sheriff: No Suspects Named, but Investigation 'Still Growing'

Pima County Sheriff Chris Nanos confirmed during a Day 24 investigative update that detectives and federal agents had returned to the Guthrie neighborhood to conduct additional canvassing. The sheriff's office also confirmed that multiple additional gloves collected from the surrounding area are currently under laboratory analysis, and that all crime scene and search warrant evidence has been submitted to labs for processing, according to the PCSD update.

Despite those ongoing efforts, Sheriff Nanos stated there are "no names his team is currently looking into" as of Day 24 — a frank admission that, more than three weeks in, investigators have yet to identify a suspect. Nanos had previously described the investigation to People magazine as "still growing" in a February 20 interview, noting the scope of the effort continues to expand even without a named person of interest.

Tip Volume Surpasses 55,000; Investigators Urge Restraint

The PCSD announced that the total volume of tips and calls received since February 1 has surpassed 55,000 — roughly 25,000 more than the same period in any prior comparable investigation, according to the department. Despite the extraordinary public response, investigators once again asked the public to refrain from calling with theories, personal opinions, or non-actionable information, emphasizing that actionable, specific tips are what move the case forward.

The tip volume underscores the national attention the case has drawn, in part because of Savannah Guthrie's public profile as a co-anchor of NBC's TODAY show. That attention has also generated online speculation targeting individuals with no verified connection to the case — a pattern authorities have had to address in recent days.

Pizza Delivery Incident Adds to Investigative Noise

Adding to the investigative backdrop, a pizza delivery driver was detained and held for approximately five hours before being released in connection with the investigation, according to TMZ, which spoke with the deliveryman's attorney, Jesse Showalter. Showalter confirmed his client was released without charges. Separately, a man identified in viral online posts as Jonathan Lee Riches — described by multiple outlets as a known attention-seeker with a history of inserting himself into high-profile cases — reportedly appeared at the crime scene area under the guise of a pizza delivery, generating online buzz but no credible investigative leads, according to reporting from Bollywood Shaadis and the Sunday Guardian.

Community Vigil Outside Nancy's Home

As the reward announcement reverberated Monday, community members gathered outside Nancy Guthrie's Catalina Foothills home to place handmade signs and flowers. Among the signs, according to AZ Central, one was addressed directly to the kidnapper and read: "Unintentional things happen, and we get that. Life is made up of choices. Please make the right one now." Marilyn Fogltance, 81, was among those who brought yellow flowers to the home, according to the same outlet.

What to Watch For Next

With the $1 million reward now public and coordinated with the FBI, investigators and the Guthrie family will be watching closely to see whether the offer generates actionable tips. The laboratory analysis of DNA and physical evidence — including the additional gloves collected from the neighborhood — remains a potential turning point. Whether the "scouting" theory can be confirmed or ruled out by investigators will also be a key development to watch, as it could significantly reshape the understanding of how and why Nancy Guthrie was targeted. As of Day 24, no arrest is imminent and no suspect has been publicly named.
