Authorities are under increasing scrutiny for their approach to the investigation into Nancy Guthrie’s disappearance, as detectives revisited her residence for the third time on Friday.

The Pima County Sheriff’s Office has faced backlash for its handling of the case, which involves the mother of Savannah Guthrie, the host of the Today show. The search, now entering its seventh day, has been criticized for inconsistencies, such as repeatedly removing and reapplying crime scene tape and overlooking a roof-mounted camera during previous searches.

In a recent development, FBI agents discovered a camera on the roof of Nancy’s Tucson, Arizona home—a detail missed during the initial searches by local police.

Additionally, a blue Subaru SUV, believed to be Nancy’s, was towed from the property for evidence processing, marking the first time this action has been taken since her disappearance.

Nancy Guthrie vanished from her $1 million home in the early hours of Sunday, February 1.

Chris Nanos, who has served as the county sheriff since 2020, has been at the center of the growing criticism surrounding the investigation.

It started with his imprecise language. On Monday, February 2, Nanos gave a wide-ranging interview to NBC News and said: ‘I think she was abducted… When you’re taken from your bed and you don’t want to go somewhere, that’s an abduction.’

Nanos later had to clarify he was speaking figuratively and that he had no evidence that Nancy literally ripped from her bed.

Chris Nanos, the county sheriff since 2020, has had public statements dissected by the national media, something he has acknowledged he is not used to

‘I just know that this 84-year-old mom, grandma, went to bed that night and in the morning she was missing,’ Nanos later told People.

Nanos has outright stated that the overwhelming media attention on him and his department is completely new for him.

‘So I apologize to you for … Sometimes I’m speaking in generalities and … and … I’m not used to everybody hanging on to my words and then trying to hold me accountable for what I say. But I understand,’ he said on Tuesday.

The Tucson Sentinel published an op-ed on Wednesday advising Nanos to wait to address reporters and the media as a whole until there are substantive updates.

‘For the most part his answers were exasperated statements that could be summed up with a Scooby Doo “Ruh ROH…,”‘ the op-ed said, referring to his presser the day before.

Things didn’t get any better for Nanos on Thursday, when he said, ‘My guesswork is as good as yours,’ when he was asked by reporters about potential suspects and motives. 

During that same press conference, Nanos acknowledged that crime scene tape around Nancy’s house was put up and taken down on four separate occasions.

When asked about potential evidentiary issues this could have caused, Nanos said: ‘I’ll let the court worry about it. We follow the rules of law.’

Nanos also said he should have called in the FBI and various regional teams to assist with the case much sooner.

On Friday, the Daily Mail reported that the sheriff’s department failed to deploy its fixed-wing Cessna aircraft to search the area around Nancy’s home immediately after she was reported missing.

The aircraft, equipped with high-resolution thermal imaging cameras capable of scanning vast swaths of desert terrain, remained on the tarmac for roughly half a day, sources close to the sheriff’s department told the Daily Mail. 

There was a staffing shortage that left the department without qualified pilots to fly the plane – a shortage people familiar with the situation blamed directly on Nanos.

Nancy was reported missing shortly after 12pm on Sunday. By 12.15pm, police arrived at her home in the Catalina Foothills, but the aircraft was not in the air until around 5pm that evening.

Matt Heinz, a member of the Pima County Board of Supervisors, told the Daily Mail that failing to get the plane airborne may have cost investigators vital opportunities.

‘The initial few hours of any kind of search like this are absolutely crucial,’ Heinz said.

Sergeant Aaron Cross, president of the Pima County Sheriff’s Deputies Association, said that trained aviators who could have crewed the aircraft had been transferred out of the Air Operations Unit in recent weeks.

Pima County Republican Party Chairwoman Kathleen Winn echoed Cross’s claim.

As of Saturday afternoon, police have not identified a suspect or person of interest in the case.

The Daily Mail approached the sheriff’s department and the FBI for further comment.
