Investigators were spotted placing evidence markers on the roof of Nancy Guthrie’s Tucson, Arizona home on Friday evening.

Both the FBI and Pima County Sheriff’s Department have returned to the 84-year-old’s home on Friday in the sixth day of the search.

Agents were also looking on the ground at the residence, looking in bushes while flashlights beamed around the premises. Orange cones line the street leading to Guthrie’s home.

Neighbors told CNN that they’re conducting new interviews with neighbors and searching around the home.

This is the third time Guthrie’s home has been searched this week.

Nancy Guthrie’s captors could have taken her in pitch-black conditions, according to reports.

The City of Tucson and Pima County code requires outdoor lighting must be shut off between 11pm local time and sunrise the following day, leading to a lack of visibility.

Additionally, footage from the Fox Flight Team showed the floodlights on Nancy’s house appeared to be broken, meaning they may not have been working when she was abducted.

A neighbor told police they should check Nancy Guthrie’s roof after she saw aerial footage on TV of the home.

‘You see in that image, you see how white her roof is,’ Laura Gargano told CNN. ‘The previous three weeks we had a lot of rain, so it would be normal for a roof to a be little dirty after it rains.’

The neighbor told police to check if the elderly woman recently had her roof recoated as it could potentially lead to suspects.

Frustration is mounting in the investigation into Nancy Guthrie’s disappearance as cops admit they have found no suspects over six days into the search.

In the days since the 84-year-old vanished from her home in Tucson, Arizona overnight Saturday, investigators have returned to the scene three times to seize evidence.

The latest search on Friday came after a ‘new message’ was sent to KOLD, a local Tucson news outlet, that appeared to be sent by people claiming to be holding Nancy for ransom.

With investigators under the spotlight, here the Daily Mail takes a look at the key evidence in the case.

The sheriff leading the investigation into the disappearance of Nancy Guthrie has been slammed over his ‘bumbling’ and ‘aloof’ press conference, as time has officially run out on the first ransom deadline.

Pima County Sheriff Chris Nanos took to the podium on Thursday afternoon as the search for Nancy, the mother of Today Show host Savannah Guthrie, entered its fifth day in Arizona.

Nanos made a carefully worded statement about Nancy, but later denied that he was suggesting that she is no longer alive.

The neighbor of Nancy Guthrie recalled seeing a suspicious white van on their street before the 84-year-old grandmother disappeared from Arizona.

Brett McIntire, 72, reported the vehicle to police after noticing it lacked any company branding, unlike normal work vehicles, he told the New York Post.

‘It was a white van, full-sized, with no printing on the sides. It was parked on the street,’ he said.

Nancy Guthrie could have been kidnapped from her Arizona home as part of a ‘revenge’ plot, a retired FBI agent has suggested.

Authorities have not identified a motive or any suspects in the case as the search for Savannah Guthrie‘s missing mother entered its sixth day.

But former FBI supervisor agent James Gagliano says the ransom note demanding Bitcoin funds is the ‘most compelling piece of evidence thus far’.

The sheriff leading the search for missing Nancy Guthrie is facing mounting allegations that his mismanagement crippled the crucial early stages of the investigation.

Multiple sources close to the Pima County Sheriff’s Department have told the Daily Mail that Sheriff Chris Nanos made a series of missteps that slowed the initial response – including the handling of the crime scene and contradictory messages being issued to the public.

We can now reveal that, according to those insiders, a vital search-and-rescue aircraft was grounded in the initial hours of the investigation when it was needed most.

A ‘vehicle of interest’ has been identified in the ongoing search for missing Nancy Guthrie after investigators said a second ‘message’ was sent to a local news station.

The developments came late Friday as a message was sent to Tucson news outlet KOLD, appearing to be sent by the same people who claimed to be holding the 84-year-old for ransom.

Soon after the letter was sent, an FBI forensics team descended on Nancy’s home, and aerial images taken by the Daily Mail show teams unloading gear to seize new evidence.

Investigators were seen scouring the area and placing new evidence markers around the property, including in hedges and on the roof of Nancy’s home.

The search for missing Nancy Guthrie escalated Friday night as investigators seized a vehicle and a camera from the roof of her home – hours after another ‘ransom letter’ was sent by her purported abductors.

Forensic teams were seen scouring the roof of Nancy’s home in Tucson, Arizona, reportedly finding a camera mounted to the property that had been missed in previous searches.

A dark SUV was also towed from the garage of the home, with Friday’s searches marking the third time investigators returned to the crime scene since Nancy was reported missing on Sunday.

Over a dozen vehicles descended on the home throughout the day, including forensics teams, FBI agents and sheriff’s deputies.

Authorities have not offered details behind the latest search, but it came just hours after a second ‘message’ was sent to Tucson news outlet KOLD, claiming to be sent by those holding the 84-year-old for ransom.

NBC’s broadcast team paused their coverage of the 2026 Winter Olympics to send support to Savannah Guthrie as their search for her mother continues.

Guthrie withdrew from her planned hosting duties with the network for the Milan-Cortina Games following the disappearance of her mother, Nancy, on February 1st.

The NBC news anchor was initially scheduled to to lead the prime-time presentation of the opening ceremony on Friday night before the family crisis occurred.
