TUCSON, Ariz. — Investigators in the Nancy Guthrie abduction case have obtained a significant DNA breakthrough that has narrowed the pool of potential suspects, Pima County Sheriff Chris Nanos announced Saturday, offering the most encouraging update yet as the search for the 84-year-old mother of NBC “Today” show co-anchor Savannah Guthrie entered its 110th day.

Forensic experts at the FBI laboratory in Quantico completed advanced genetic genealogy analysis on a rootless hair sample and partial glove DNA recovered from Guthrie’s Catalina Foothills home. The results have generated several strong investigative leads, including matches to distant relatives of individuals with prior connections to the Tucson area, sources familiar with the probe told local media.

“We are making real, measurable progress,” Nanos said during a brief update. “The genetic genealogy work has opened doors that simply weren’t available in the first weeks of this investigation. We are closer today than we have been at any point.” He declined to provide specifics, citing the active nature of the case, but confirmed that multiple persons of interest are now under closer scrutiny.

Nancy Guthrie disappeared from her secure residence on February 1, 2026. Security footage captured a masked individual near her door in broad daylight. Blood evidence, a disabled Ring camera, propped-open doors and clear signs of a struggle led authorities to classify the incident as an abduction. No ransom demand has ever been received, and no arrests have been announced despite an intensive multi-agency effort involving local police, the FBI and private investigators.

Savannah Guthrie has continued balancing public appeals for information with her anchoring duties on the “Today” show. In recent weeks she has worn yellow — the color of hope — during several broadcasts while expressing quiet gratitude for the public’s ongoing support. The family maintains a $1 million reward for information leading to Nancy’s safe return or the identification and arrest of those responsible.

New Leads Spark Renewed Hope

The genetic genealogy results represent the most tangible advancement since the early days of the case. Law enforcement has been cross-referencing partial DNA profiles against public genealogy databases and private family trees. While officials have not named any suspects, sources indicate that at least two individuals with potential ties to the Tucson metro area are now persons of interest.

The unrelated discovery of ancient human bones near the home several weeks ago briefly raised hopes before forensic analysis confirmed they were decades old. That episode, while disappointing, underscored the exhaustive nature of the search effort across Arizona’s desert terrain.

Criminal behavioral analysts have suggested the perpetrator may have had some degree of familiarity with the neighborhood or the victim. The brazen daytime abduction in an upscale gated community continues to puzzle investigators. Some experts lean toward a burglary gone wrong, while others have not ruled out a targeted act possibly linked to personal grievances.

Community and National Attention

Yellow ribbons remain tied to trees and lampposts throughout Catalina Foothills. Neighbors continue informal vigils and information-sharing through community groups. The case’s visibility, amplified by Savannah Guthrie’s national platform, has kept tips flowing into the dedicated hotline.

Elizabeth Smart, who was abducted as a teenager in 2002, has remained in contact with the Guthrie family. “I still believe Nancy could be found alive,” Smart said in a recent interview. “These cases can stretch on for a long time, but hope is a powerful force.”

The emotional toll on the Guthrie family is evident. Savannah briefly stepped away from the “Today” show earlier this month due to exhaustion but returned after a short break. She and her siblings continue advocating for Nancy while trying to maintain normalcy for the younger children in the extended family.

Investigation Challenges Persist

Despite the DNA progress, significant hurdles remain. Multiple ransom-style notes sent to media outlets have been evaluated as probable hoaxes. No credible proof of life has surfaced in more than 110 days, yet authorities continue operating under the assumption that Nancy may still be alive.

Coordination between local, state and federal agencies has improved after early tensions. FBI Director Kash Patel publicly criticized initial information sharing but now describes the joint effort as “productive and focused.” Hundreds of law enforcement personnel have contributed at various stages, with resources dedicated to surveillance review, extensive canvassing and tip-line management.

The vast desert landscape surrounding Tucson presents unique search challenges. Specialized teams using drones, cadaver dogs and ground-penetrating radar have covered hundreds of acres without success. Officials say they will not scale back efforts even as the case moves deeper into its fourth month.

Sheriff Nanos Under Pressure

Sheriff Chris Nanos, a Democrat elected in 2018 and re-elected in 2024, has faced quiet but growing political pressure as the high-profile case drags on. Some local critics have questioned resource allocation and communication strategies, though no formal calls for resignation have emerged. Nanos has repeatedly vowed that the investigation remains a top priority and that his department will not rest until answers are found.

What Comes Next

Authorities have renewed their public appeal for tips, particularly any information about vehicles or individuals acting suspiciously in the Catalina Foothills area in late January or early February. Forensic testing is expected to continue yielding results in the coming weeks, with additional genetic genealogy work planned.

For the Guthrie family, each new development brings a painful mix of renewed hope and prolonged uncertainty. Friends and colleagues have formed a quiet support network, with “Today” show personalities offering both public encouragement and private assistance.

The disappearance of Nancy Guthrie has highlighted vulnerabilities even in affluent, protected communities and the enduring power of hope amid uncertainty. Whether the case ultimately ends in a joyful reunion or provides answers through other means, it has already left a deep imprint on those following the story — a testament to one family’s resilience and a community’s determination to bring Nancy home.

As the investigation pushes past 110 days, the combination of traditional detective work and cutting-edge forensic science offers the best chance yet for resolution. Sheriff Nanos and his team continue working around the clock, supported by federal partners and the unwavering hope of a family that refuses to give up.

Cerebras headlines a busy IPO week with surging investor demand. (0:17) Applied Materials faces AI demand questions. (1:12) April CPI arrives with energy prices driving inflation concerns. (1:55)

As earnings season winds down, attention is shifting to the IPO market.

AI chipmaker Cerebras Systems (CBRS) headlines a busy week for new listings.

Reports indicate the company may raise its price range to $125 to $135 per share as soon as Monday, lifting the potential proceeds to about $3.78B from $3.5B. The deal has reportedly attracted orders more than 20 times the shares available, and the range could still move higher.

Cerebras plans to sell 28M shares on the Nasdaq under the ticker CBRS, with Morgan Stanley, Citigroup, Barclays and UBS leading the underwriting syndicate.

Also expected to begin trading are geothermal developer Fervo Energy (FRVO), which has a data center partnership with Google (GOOGL), and data center REIT Blackstone Digital Infrastructure Trust (BXDC), both with projected valuations north of $5B.

Other IPOs slated for the week include GMR Solutions (GMRS), EagleRock Land (EROK), and Riku Dining Group (RIKU).

On the earnings calendar, Applied Materials (AMAT) takes center stage Thursday.

Investors are looking for another beat-and-raise quarter from one of the market’s key AI infrastructure beneficiaries.

The primary growth drivers remain gate-all-around transistor demand and high-bandwidth memory. AMAT’s $5B EPIC Center initiative is also in focus, with investors watching for updates on customer co-development, commercialization timelines, and the strength of AI-related demand.

China remains the principal risk. Management has already flagged a potential $600M revenue headwind in FY2026 tied to tighter U.S. export restrictions.

Elsewhere this week:

Simon Property Group (SPG) reports Monday, Oklo (OKLO) Tuesday, and Tencent (TCEHY), Cisco (CSCO), and Alibaba (BABA) on Wednesday.

On the economic front, the April consumer price index arrives Tuesday, with the headline rate expected to rise to 3.6% while core inflation holds near 2.6%.

Wells Fargo economists say elevated energy prices tied to Middle East tensions are beginning to generate broader spillovers.

“Energy goods are poised for a 6% monthly gain as higher crude prices continue to pass through to the pump,” they wrote. “Food at home is likely to accelerate after March’s pullback, with grocery prices strengthening later this year amid rising transportation and fertilizer costs.”

They added that services inflation, excluding shelter, could run hot as higher jet fuel prices push airfares higher.

Seeking Alpha analyst Chris Lau said a hotter CPI print would increase the odds of tighter policy, though Fed officials will need to assess whether energy-driven inflation tied to the Strait of Hormuz proves transient or persistent.

In the news this weekend, Lumentum Holdings (LITE) is set to join the Nasdaq-100 (NDX) (QQQ), replacing real estate services firm CoStar Group (CSGP) later this month.

Nike (NKE) is facing a proposed class action lawsuit alleging it failed to refund tariff-related costs passed on to customers through higher prices.

The case is part of a broader wave of lawsuits against U.S. companies after the Supreme Court ruled against sweeping tariffs imposed under the International Emergency Economic Powers Act last year.

In the federal complaint, plaintiffs argue Nike is not entitled to retain the “significant” refunds it is expected to receive following the ruling. Nike has said the tariffs forced it to pay roughly $1B in import levies.

And for income investors:

Apple (AAPL) goes ex-dividend Monday, paying out May 14.

Visa (V) goes ex-dividend Tuesday, with a June 1 payout.

Target (TGT) goes ex-dividend Wednesday, also paying out June 1.

Delta (DAL) goes ex-dividend Thursday, with a May 28 payout.
