The search for 84-year-old Nancy Guthrie has entered its third week, with investigators still working to piece together what happened the morning she vanished from her home in Tucson, Arizona. It has now been 18 days since she was last seen.
Authorities say forensic testing has not yet provided a breakthrough. Pima County Sheriff Chris Nanos confirmed that DNA recovered from a glove found near Guthrie’s home, as well as samples collected inside the residence, did not match any profiles in the FBI’s database.
As the investigation widens, federal agents have been following multiple leads. An Arizona gun store owner told Fox News Digital that an FBI agent recently asked him to review firearm purchases connected to a list of nearly two dozen individuals. It is not clear how those names are tied to the case, but the outreach signals that investigators are exploring a broad range of possibilities.
The FBI has also released a description of a person of interest captured on surveillance footage. According to investigators, a man wearing a mask and gloves was seen tampering with the doorbell camera outside Guthrie’s home in the early morning hours of Feb. 1, around the time she is believed to have disappeared.

The individual is described as a male between 5 feet 9 inches and 5 feet 10 inches tall, with an average build. He was carrying a 25-liter Ozark Trail Hiker Pack backpack.
In an effort to generate new leads, the FBI initially raised the reward for information leading to Guthrie’s location, or to the arrest and conviction of anyone involved in her disappearance, to $100,000. On Wednesday, an anonymous donor stepped forward, pushing the total reward to $200,000.
As investigators continue their search, neighbors say the disappearance has shaken what was once a quiet Tucson community.
Lloyd Anderson, who lives near Nancy Guthrie and attended church with her, told Fox News Digital that the uncertainty has prompted him to take extra precautions at his own home. In the days after she went missing, he decided to add security cameras to his home.
“I have had alarms, and I just recently put cameras in too,” Anderson said, noting that the upgrades came after Guthrie vanished.
For many in the neighborhood, the situation feels unfamiliar and deeply unsettling.

“It’s certainly different. We’ve never gone through this before. It’s something we just have to live through,” he said. “And I knew Nancy, and I think she was a wonderful lady. And I think we just got to give her our best wishes and God’s help.”
Anderson said he knew Guthrie through church and from seeing her regularly around the area.
“She sat in church, and I knew her from the neighborhood here,” Anderson said. “And just like I’m doing now, walking by her house.”
When he noticed she had stopped attending services, he reached out.
“I called her the first part of January and asked her why we hadn’t seen her,” he said, explaining that she had started attending other church gatherings and Bible discussions.
As the search stretches on, neighbors like Anderson say they are holding on to hope while adjusting to a new sense of caution in their daily lives.
