Investigators have announced that they now believe missing woman Nancy Guthrie is presumed deceased, based on the evidence gathered throughout the course of the ongoing investigation.

According to law enforcement officials, this determination follows an extensive review of physical evidence, digital records, and investigative leads developed since Guthrie was first reported missing.

Authorities have indicated that the totality of the circumstances — including the absence of any verified contact, communication, or financial activity — has led investigators to conclude that her disappearance is no longer being treated solely as a missing persons case but as a suspected homicide investigation.

Officials emphasized that while Guthrie’s body has not yet been recovered, the evidence uncovered thus far supports the presumption that she is deceased. Law enforcement agencies continue to pursue all credible leads and are working closely with forensic specialists and partner agencies to locate her remains and identify those responsible.

A significant law enforcement operation unfolded late last night at a residence in the 32000 block equivalent area of 6280 N. Placita de Rojelio in Tucson, Arizona, following what authorities described as a tip and investigative lead.

According to publicly available records, the individual believed to be the focus of the operation was Luke Anthony Daley, 37, who has prior criminal cases involving drug and weapons-related charges. Court records indicate multiple criminal filings (designated with “CR” case numbers).

His brother, Matthew Daley, 39, was also detained during the operation. Reports suggest one brother was located at the residence while the other was associated with a vehicle at the scene.

Authorities have not confirmed the identity of an additional male detainee reported at the location.

The residence is reportedly owned by Mary C. Daley, believed to be in her 70s. Officials have not publicly detailed the specific reason for the search or whether arrests were made in connection to the disappearance of Nancy Guthrie.

Around the same time as the SWAT activity, FBI agents were observed stopping and investigating a silver Range Rover approximately two miles from Nancy Guthrie’s home. The vehicle was later towed after agents examined its contents. Photographs showed part of the trunk area covered with a sheet while agents processed the scene.

Vehicle records indicate the Range Rover had reportedly been sold on February 13, 2026. The dealership connected to the sale has been identified in public discussion as MG Motors in Tucson. Federal authorities have not confirmed whether the vehicle is directly connected to the disappearance, stating only that they are pursuing investigative leads.

The individual is reported to be a part owner of Tucson MG Motors, a Range Rover dealership based in Tucson. Records indicate prior arrests in Tucson allegedly connected to individuals described as part of a Russian organized crime network. These circumstances have prompted public speculation regarding whether individuals associated with Russian criminal enterprises may be involved.

According to observers, the Range Rover vehicle seized by the FBI reportedly bore license plate information linked to the dealership. The vehicle is said to have been purchased recently.

Additionally, questions have been raised about Zaidoun Jaghoub, identified as an accountant who is alleged to have connections with affluent individuals in the Middle East. Both names have been mentioned in connection with the used car dealership associated with the vehicle taken into custody by federal authorities.

At this time, there is no confirmed evidence publicly establishing wrongdoing by any specific individual. However, the dea

Earlier, Sheriff Chris Nanos had mentioned in interviews that investigators were searching for a gray truck or SUV with a covered license plate. Surveillance footage reportedly captured a gray vehicle in Nancy’s driveway on the night of her disappearance. Authorities have not publicly confirmed whether the Range Rover is the same vehicle referenced earlier.

Initial scanner traffic and early media reports incorrectly linked the SWAT activity to the home of County Attorney Baird Greene. Officials later clarified that the residence targeted was a different property nearby. The Pima County Sheriff’s Office issued a statement correcting the record.

The FBI has confirmed it is actively involved in the investigation into Nancy Guthrie’s disappearance. Officials have stated that DNA evidence recovered from her property does not belong to Nancy or individuals known to be in close contact with her. The origin of the DNA remains under investigation.

Law enforcement sources indicate forensic testing is ongoing, including analysis of items collected from the scene. Authorities have not publicly commented on inter-agency coordination beyond confirming that both local and federal agencies are involved.

The FBI has raised the reward for information leading to an arrest to $100,000.

Officials installed specialized equipment on a Pima County Sheriff’s helicopter in an effort to detect potential radio-frequency signals associated with Nancy Guthrie’s pacemaker. The 84-year-old had a medical device capable of syncing with her iPhone and Apple Watch.

Investigators noted that the pacemaker stopped syncing with her devices at approximately 2:30 a.m. on the morning she disappeared. Authorities have not confirmed whether the aerial search technology produced actionable results.

Earlier in the week, Tucson resident Carlos Palazuelos was detained in connection with the investigation but was later released without charges after authorities determined he was not connected to the disappearance.

The FBI released surveillance footage from Nancy’s Nest doorbell camera showing a masked individual wearing nitrile gloves approaching her home the evening she disappeared. The person appeared to examine the camera and attempt to obstruct its view with flowers.

Because Nancy did not have a paid Nest subscription, investigators reportedly worked with Google to retrieve stored footage from servers.

A forensic sketch artist, Lois Gibson of Houston, later shared an interpretive sketch based on the limited visible facial features. Gibson stated that only the eyes and portions of the lips and mustache area could be partially inferred from the footage.

Several ransom communications demanding up to $6 million have reportedly been sent to media outlets.

Law enforcement has not verified their authenticity. Deadlines referenced in those communications have passed without confirmation of legitimacy.

The case has drawn widespread national attention, in part due to Nancy Guthrie being the mother of NBC’s Today show anchor Savannah Guthrie.

Reports indicate that Savannah has been deeply affected by the investigation and is reassessing her professional commitments amid the ongoing search.

Sources cited by NewsNation describe the situation as emotionally overwhelming for the family.

The Pima County Sheriff’s Office and FBI continue to pursue leads.

Officials have stated that they will release further updates when appropriate but emphasized that certain investigative details cannot yet be disclosed.

The search for Nancy Guthrie remains active.
