Authorities released photos and videos on Feb. 10, of a potential suspect who was caught tampering with a camera on her front door on the morning of her disappearance.
No arrests have been made.DNA evidencehas been collected and submitted for analysis, though authorities have warned this process will take time. But investigators have been making progress as they seek to identify the clothing worn by the suspect in the security camera footage, according to Nanos.
For onlookers, the investigation has provided limited clues and false starts, most recently with therecovery of a backpack that proved fruitless. Earlier in the month, authorities also recovered gloves that seemed to match those worn by the suspect, but a DNA analysis did not turn up any matches in the FBI's national database. Two individuals have also been detained during the investigation, but both were but quickly released.
The FBI is offering a $100,000 reward for information leading to Guthrie's recovery and/or the arrest and conviction of anyone involved in her disappearance.

Search for Nancy Guthrie and person suspected of taking her continues
New imagesreleased by authorities on Feb. 10, 2026, from a Nest camera outside Nancy Guthrie's home show an armed individual appearing to have tampered with the camera at the front door on the morning of her disappearance on Feb. 1.
Authorities have not ruled out the possibility of more than one person being involved in Guthrie's disappearance. Law enforcement has, however, ruled out all members of the Guthrie family as suspects.
"The family has been nothing but cooperative and gracious and are victims in this case,"Nanos previously said."To suggest otherwise is not only wrong, it is cruel."
What evidence are investigators looking at?
The Pima County Sheriff's Department confirmed on Feb. 13 that DNA "other than Nancy Guthrie's and those in close contact to her has been collected from the property" and submitted for analysis. "We believe that we may have some DNA there that may be our suspect,"Nanos told NBC News. "But we won't know that until that DNA is separated, sorted out."
On Feb. 20, the sheriff's department said in an update that DNA analysis "is underway on biological evidence recovered during the investigation" but warned that "this process can be lengthy."
Nanostold NBC Newson Feb. 20 that investigators are "getting a little closer to identifying some of the other articles" of clothing worn by the suspect in the door camera video. Investigators have also been working with Walmart to identify the person who purchased the backpack seen in the video.
Guthrie's pacemaker was another investigation focus that law enforcement mentioned last week. "Investigators are attempting to locate the device and are working with the manufacturer and other experts in the field to assist in that effort," the sheriff's department said on Feb. 17. Guthrie's pacemaker app showed it was disconnected from her phone at 2:28 a.m. the morning of her disappearance, according toauthorities' previously released timeline.
Nancy Guthrie: Backpack found in search
Volunteers have been searching the area and on Feb. 22 recovered a backpack, which was handed over to a deputy. But the Pima County Sheriff's Department confirmed on Feb. 23 that "after reviewing the bag and its contents, it does not appear that this is a viable lead for the investigation."
The bag does not seem to be the same brand of backpack that was seen in the doorbell surveillance footage, and it also "appears to have been outside for much longer than three weeks" and contained the identification of a minor, according to the sheriff's department.
