Fifteen days after 84-year-old Nancy Guthrie disappeared from her Tucson-area home, investigators announced a major development that initially seemed like a breakthrough. The Federal Bureau of Investigation confirmed that a glove recovered about two miles from the residence appears to match the gloves worn by a masked individual captured on Nest surveillance footage outside the home. The footage showed the person approaching the front door and attempting to cover the camera with leaves. Even more significant, the glove contained a DNA profile that differed from DNA previously collected at the house. Authorities prepared to upload the profile into CODIS, the FBI’s national DNA database, raising hopes of a quick identification if a match to a known offender or relative was found.

However, in a twist few expected, the Pima County Sheriff’s Department later revealed that the DNA from the glove produced no matches in CODIS. Officials also confirmed that separate DNA evidence found at the residence remains under analysis, meaning investigators are now working with at least two unknown profiles. Experts cautioned that forensic testing takes time and does not guarantee immediate answers. Meanwhile, authorities continue reviewing digital clues, including signal data from Nancy’s pacemaker and other electronic evidence, while also assessing tips that suggest the suspect could have left the country. Rather than closing the case, the glove discovery has deepened the mystery and shifted the investigation in an unexpected direction.
