Meanwhile, investigators are chasing DNA that doesn’t match, analyzing biological evidence still in the lab, probing recent gun purchases, and even scanning for signals from Guthrie’s pacemaker, which mysteriously disconnected from her phone hours before she was reported missing. Gloves with unknown DNA found miles away. Extra security cameras still being processed. A possible second person involved. Someone knows what happened that night. And authorities believe this case is far from random.

Accomplice not ruled out in Nancy Guthrie disappearance, Arizona sheriff says

Investigators have not ruled out that an accomplice aided the suspected kidnapper seen in doorbell camera video outside the Tucson, Arizona, home of Nancy Guthrie the night of her disappearance, according to Pima County Sheriff Chris Nanos.

Authorities believe Nancy Guthrie, 84, was forcibly taken from her home in the middle of the night before she was reported missing Feb. 1. Nanos told CBS News partner network BBC News in an interview Tuesday that he believes Guthrie was targeted in the apparent abduction.

The video recovered from Guthrie’s Google Nest doorbell camera, which was shared by the FBI last week, is the only video that Google has been able to recover from the cameras at Guthrie’s home, according to the Pima County Sheriff’s Department. There are additional cameras from the property that engineers are still working through as they try to recover usable video. Investigators are hopeful that tech companies working on the videos will uncover more, according to the sheriff’s department.

A reward from the 88-CRIME tipline was increased on Thursday to $102,500 — thanks to a $100,000 anonymous donation, the organization said — for information leading to the arrest of the person or persons involved in Guthrie’s disappearance. That reward is in addition to a $100,000 reward the FBI is offering.

Authorities haven’t named a suspect or person of interest in the case, and did not provide further information about a possible accomplice. The FBI described the suspect seen in the doorbell camera video as a male who is between about 5 feet, 9 inches and 5 feet, 10 inches tall with an average build.

“Today” show co-host Savannah Guthrie, her two siblings and their spouses were all cleared as suspects in the case, the Pima County Sheriff’s Department announced Monday as the high-profile investigation entered its third week.

Nanos said the Guthrie family has cooperated with investigators.

“We really put them through the wringer,” Nanos said. “We not just interview them, we take their cars, we take their houses, we take their phones, all this stuff — and we’re not taking it. They’re giving it to us voluntarily. They have been 100% cooperative with us through everything we’ve asked. They are victims. They are not suspects.”

Nancy Guthrie was last seen on the night of Jan. 31 when her son-in-law, Tommaso Cioni, dropped her off at her house after she spent the evening with him and her daughter, Annie Guthrie, at their home, authorities said.

Since Nancy Guthrie’s disappearance, Savannah Guthrie, Annie Guthrie and their brother, Camron Guthrie, have appeared in videos pleading for their mother’s return.

Investigators were looking into genetic genealogy options to check for matches with DNA evidence collected in the case after a DNA profile from a set of gloves didn’t produce a match in a national database maintained by the FBI, the sheriff’s department said Tuesday. The gloves were found about 2 miles away from Nancy Guthrie’s home.

The DNA profile also didn’t match with different DNA evidence collected at the home, the sheriff’s department said.

The sheriff’s office said Thursday that “biological evidence” found at Nancy Guthrie’s home was being analyzed and DNA profiles were “under lab analysis.”

Law enforcement sources told CBS News that investigators have been using a tracking device known as a “signal sniffer” in an effort to detect possible signals from Nancy Guthrie’s heart pacemaker, which showed a disconnect from her phone in the early morning hours the night she went missing.

CBS News has also learned the FBI is probing gun purchases in the Tucson area. According to the owner of an area gun store, an agent came in about a week or so ago and showed him several images with faces and names on them, and agents inquired about purchases in the last year.

Colbert says network lawyers pressured him not to air it. CBS says that’s not true. Meanwhile, the political backdrop is anything but quiet — from corporate mergers to renewed “equal time” scrutiny from the FCC.  And here’s the twist: Talarico’s campaign reportedly raised $2.5 million in the fallout.  A segment that never aired on television just became one of the most-watched political interviews online.  So what was said that sparked 85 million views — and a network standoff?
Unknown DNA. And what used to be a dead end is now the most powerful lead in the case.  Investigators searching for answers in the disappearance of Nancy Guthrie are diving into investigative genetic genealogy — the same cutting-edge technique that helped identify the Golden State Killer and track Bryan Kohberger.  The glove found two miles from her Tucson home didn’t match anyone in CODIS. DNA collected at the house didn’t match either. Years ago, that would have stalled the case.  Now? It could be the breakthrough.  By combing through public DNA databases, experts can identify distant relatives of an unknown suspect — sometimes from less than 1% shared DNA — and build a family tree that narrows the search to a single name. It can take minutes. Or it can take years.
A masked man. A single glove. And now — DNA that could unmask a kidnapper.  Three weeks after 84-year-old Nancy Guthrie vanished from her Tucson home, investigators are turning to cutting-edge genetic genealogy in a high-stakes effort to identify a suspect. DNA recovered near the scene didn’t match anything in the FBI’s CODIS database. But authorities believe they may have found genetic material that belongs to the person who took her.  If that’s true, experts say it’s only a matter of time.  The same investigative technique helped catch the Golden State Killer and Bryan Kohberger. Now it could expose whoever was caught on camera outside Guthrie’s home — armed, masked, wearing a distinctive Ozark Trail backpack.  More than 19,000 tips have poured in. A reward exceeding $200,000 is on the table. Federal, state, and local agencies are combing through partial DNA, security footage, credit card trails, even backpack sales across Arizona.  And the sheriff has a warning: if you’re responsible, you should be worried.  Because this case isn’t cold. And the science may be closing in.
Officials say the victim’s spouse was not part of the rescue operation — but the emotional toll on the tight-knit search and rescue community is profound. “We’re all trying to support the family,” Woo said.  As identities remain unconfirmed and the storm refuses to let up, the tragedy is rippling through Lake Tahoe’s ski world — from elite academies to volunteer rescuers who now find themselves grieving while still on duty.  When the call for help came in, they answered.
Multiple victims had deep ties to Sugar Bowl Resort and its elite ski academy — a tight-knit community that has produced Olympians and generations of Tahoe athletes. Friends. Mothers. Longtime ski partners who made this trip every year.  They were experienced. It was guided. So how did everything unravel so fast?  As rescue crews battle relentless storms and families wait for answers, the tragedy is sending shockwaves from Mill Valley to Stanford to the heart of the Sierra.  And the hardest questions are only just beginning.
With extreme warnings in place, brutal storm conditions rolling in, and a 15-person group navigating high-risk terrain near Lake Tahoe, investigators are now piecing together a tragedy that has shaken the entire ski community. Was it the weather? The route? A split-second decision? Or a cascade of factors no one saw coming?  Rescue teams still can’t reach the victims. Families are left with heartbreak — and “many unanswered questions.”  This wasn’t a reckless adventure. These were experienced women who loved the mountains.  So how did it end like this?
