Nancy Guthrie Update Today: New Home Camera Images Show No Suspicious Activity on Day 46
The search for Nancy Guthrie enters its 46th day on Wednesday, March 18, 2026 — with investigators releasing the most significant surveillance development in weeks, only to confirm it produced no new leads. New images recovered from cameras across the 84-year-old's Tucson property show nothing suspicious, leaving the case as the most high-profile unsolved abduction in the country with a $1.2 million reward still unclaimed.
Nancy Guthrie Update Today — New Camera Images Show Nothing Suspicious
Investigators have been able to retrieve additional images from some of the other cameras on Guthrie's property, but they do not show suspicious activity, according to two people briefed on the matter who spoke with NBC News.
The images were taken from a camera fastened to a fence focused on the back of the house and another showing the driveway and front of the garage door. They captured family members, landscapers, and pool workers stretching back weeks prior to the kidnapping. Nothing was deemed suspicious, and no images reviewed showed the suspect captured on the front door camera.
The Only Known Image of the Suspect — Ski Mask, Backpack, Holster
The person previously seen on doorbell camera video in front of Nancy Guthrie's home wearing a ski mask, backpack, and holster on the night she disappeared does not appear in any of the newly recovered footage. The previously released doorbell footage remains the only known image that authorities have of the suspect.
The suspect remains described by the FBI as a male approximately 5 feet 9 inches to 5 feet 10 inches tall with an average build, last seen wearing a black Ozark Trail hiker backpack. Investigators are still working to process mixed DNA recovered at Nancy Guthrie's property, and Sheriff Nanos has expressed hope the DNA will lead to a suspect.
Investigators Expand Timeline — Asking About January 24, One Week Before Abduction
As the search for Nancy Guthrie reaches its 46th day, investigators have broadened the range of dates they are examining for clues. Neighbors told NewsNation that investigators have been specifically interested in camera footage from January 24 — approximately one week before Guthrie is believed to have been taken.
One neighbor told NBC News she was asked about footage from January 24, a week before Guthrie was last seen. Investigators are still examining the possibility that the suspect visited Guthrie's home prior to her abduction — a theory that Sheriff Chris Nanos has not publicly ruled out.
Cadaver Dogs Pulled From Search — Expert Says Decision "Defies Logic"
The Pima County Sheriff's Department is no longer deploying cadaver dogs as part of the investigation. A retired K-9 expert said the decision defies logic, adding there are only two implications — either she is still alive, or investigators have given up searching for her.
The expert added that after six weeks without proof of life or anything else, the family has likely come to terms with the possibility that this is a homicide investigation and must be treated accordingly. Savannah Guthrie acknowledged the same painful reality in a public Instagram video last month.
Entire Guthrie Family Cleared — All Pass Polygraph Tests
All of Nancy Guthrie's family members — including Savannah, her sister Annie Guthrie, brother-in-law Tomasso Cioni, and brother Camron Guthrie — have passed polygraph tests. Pima County Sheriff Chris Nanos stated clearly that the Guthrie family are victims plain and simple and that suggesting otherwise is not only wrong, it is cruel.
The Pima County Sheriff and the FBI have not publicly named a suspect. Two men were briefly detained as separate warrants were being served in connection with the case — both were released without charges.
DNA Expert Calls for Fresh Swabbing of Nancy Guthrie's Home
A genetic genealogist and DNA expert said she would go back and re-swab parts of the house, looking for even a rootless hair — noting that modern forensic techniques can now solve cases with just that level of evidence. Sheriff Nanos previously told NBC News that investigators have been having difficulties processing mixed DNA found at the property, suggesting the mixture could contain DNA from several people.
$1.2 Million Reward and What Comes Next in the Investigation
Over 1,500 potential leads have come into the FBI since the Guthrie family announced a $1 million reward, which has since grown to a combined $1.2 million. It has been nearly three weeks since the family last called on the public for help and more than a month since law enforcement held a news conference to discuss the case.
One investigative expert told CBS News that the extended timeline means the investigation becomes much harder to keep going — but added she remains hopeful, suggesting the silence from law enforcement could mean they are on to something significant. Anyone with information is urged to contact the FBI tip line at 1-800-CALL-FBI or the Pima County Sheriff's Department tip line at 520-351-4900.
