Nancy Guthrie Day 18: CODIS Fails, the Glove Is a Dead End, and the Investigation Can't Keep Up

Eighteen days after 84-year-old Nancy Guthrie was taken from her home in the Catalina Foothills outside Tucson, the evidence the nation was banking on just came back empty. DNA recovered from a black glove found two miles from Nancy's home produced no matches in CODIS, the FBI's national database of over 26 million offender profiles. But the bigger problem isn't the miss — it's the fact that this glove was never the evidence everyone pretended it was.

A generic disposable glove found on a desert roadside, visually compared to grainy black-and-white Nest camera footage, elevated to the centerpiece of a national investigation. And now we know the DNA on the glove doesn't even match the DNA found inside Nancy's home. Two separate unknown male profiles. Two dead ends. Meanwhile, the evidence Sheriff Chris Nanos himself says is more critical — biological material recovered from inside the residence — still hasn't been fully processed for database submission.

The Pima County Sheriff's Department confirmed investigators are now pursuing genetic genealogy, the same technique that cracked the Bryan Kohberger case. But genealogy takes weeks, sometimes months. For an 84-year-old woman who requires daily medication and has a pacemaker, that timeline is a luxury she may not have.

While the glove dominated headlines, a far more significant development went largely unnoticed. A Tucson gun store owner revealed that FBI agents visited his shop with printed pages showing 18 to 24 individuals — photographs and names — asking him to check firearm purchase records. The agent's list featured men with similar physical characteristics matching the suspect profile from the doorbell footage. Yet on Tuesday, Sheriff Nanos publicly denied that investigators have narrowed the suspect pool. The contradiction between what's happening on the ground and what's being said at press conferences tells its own story.

Perhaps the most troubling revelation: investigators are only now asking Google to attempt recovery of footage from additional cameras on Nancy's property. The front door camera was recovered from backend systems within the first two weeks. A driveway angle showing a vehicle could change this case overnight. That request should have been made before dawn on February 1st, not discussed publicly as a hopeful possibility on day 18. Parsons Corporation has confirmed its BlueFly sensor technology has been scanning for Nancy's pacemaker signal since February 3rd — by air, by ground, on foot — with no results. Forty to fifty thousand tips. Multiple warrants. Zero arrests. The effort is there. Whether the urgency has matched the moment is a different question entirely.
