Nancy Guthrievanished from her Tucson home in the early hours of 1 February, and now investigators say DNA tests on a glove found nearby on 15 February show it belonged to a local restaurant worker who has no connection to the missing 84-year-old or her disappearance.
The news came after detectives had briefly treated the single glove, discovered about two miles from Guthrie's residence, as one of the most promising pieces of physical evidence in the case. The item appeared similar to gloves worn by a masked and armed man seen on security footage at Guthrie's home, raising hopes that it might put a name, or at least a profile, to the shadowy figure caught on camera.
The glove wasfoundduring the wide search that followed Guthrie's disappearance from her Tucson property in Pima County, Arizona. Deputies and federal agents have spent weeks combing the surrounding desert and suburban streets, following up tips and reviewing hours of video after Nest doorbell footage released on 10 February showed an unidentified intruder on her property.
At first glance, the glove seemed to sit neatly within that emerging picture. According to reporting by PEOPLE magazine, its design was similar to what the masked man appeared to be wearing in the home surveillance footage. In a case with no confirmed suspect and no clear crime scene beyond a bloodstained front porch, it looked, briefly, like a lifeline.
Pima County Sheriff Chris Nanos has now publicly ruled that out. Speaking to local station KVOA, he said DNA analysis linked the glove to a person working at a restaurant near where it was discovered.
'We knew that at that time, we believed wholeheartedly that those gloves belonged to a restaurant and guess what? The owner of the glove, we found working at a restaurant across the street,' Nanos said. 'It has nothing to do with the case.'
The Pima County Sheriff's Department reinforced that on 4 March in a statement on X, confirming that the individual identified through the DNA match 'is not part of this investigation.' That shuts down what had looked like a potentially direct route to the suspect and forces detectives back to a broader, less tidy mix of digital clues, laboratory work and public appeals.
Investigators have not run out of forensic material, but what remains is harder to interpret. Sheriff Nanos said other gloves are still undergoing testing at a laboratory in Florida. Those items, which have not been described in detail, are producing what he called mixed DNA profiles.
'It's a challenge because we know we have DNA, but now we have to deal with that mixture and how we're going to separate it,' he told KVOA.
Mixed samples can include genetic material from more than one person, sometimes layered through contact, contamination or simple everyday use. In practical terms, it means the science is moving more slowly than the urgency of the case, and any clear answer about whether those gloves belong to the masked assailant, an innocent passer-by or someone else entirely is still some way off.
