Behind the scenes sorting through tips in cases like the Nancy Guthrie disappearance

TUCSON, Ariz. (AP) — An Arizona sheriff's department got more than 4,000 calls within 24 hours after the release of videos of a masked person on Nancy Guthrie's porch. Many tips will be worthless. Others could have merit. Experts say one thing's certain: They can't be ignored.

Tips can solve crimes — big or small — and eerie images of a mysterious male covered head to toe have been the most significant clues shared with the public during Guthrie's nearly two-week-old disappearance in the Tucson area.

Late Friday night, the investigation prompted officers to block off a road into a neighborhood about 2 miles (3.2 kilometers) from Guthrie’s house. A parade of sheriff’s and FBI vehicles were waved through the roadblock, including forensics vehicles. The Pima County Sheriff’s Department said the activity is part of the Guthrie investigation.

Sorting through the tips is a tremendous amount of work, said Roberto Villaseñor, a former Tucson police chief.

“In a situation like this, you really cannot do what's been done without tips and public input,” he said. “They have processed the scene. But once that’s done and exhausted, it's hard to move forward without additional information coming in.”

The Pima County sheriff and the FBI announced phone numbers and a website to offer tips about the apparent kidnapping of Guthrie, the 84-year-old mother of NBC “Today” co-anchor Savannah Guthrie. Several hundred detectives and agents have been assigned to the case, the sheriff's department said.

The FBI said it has collected more than 13,000 tips since Feb. 1, the day Guthrie was reported missing. The sheriff's department, meanwhile, said it has taken at least 18,000 calls.

"Every tip is reviewed for credibility, relevance, and information that can be acted upon by law enforcement," the FBI said Thursday on X, adding that the effort is a 24-hour operation. It said it won't comment on the tips received.

Law enforcement agencies are continuing to gather potential evidence. Investigators found several gloves, the nearest about 2 miles (3.2 kilometers) from Guthrie's home, and submitted them for lab analysis, the sheriff’s department said.

They collected DNA from Guthrie's property which doesn't belong to Guthrie or those in close contact with her, the department said. Investigators are working to identify who it belongs to.

The sheriff released a statement that stressed how his department is working with the FBI. “The Pima County Sheriff’s Department and the FBI continue to work jointly on this case. Our strong partnership is critical, and we remain fully committed to this collaborative investigation.”

Evidence requiring forensic analysis is being sent to the same out-of-state lab that has been used since the beginning of the case, something local FBI leadership agreed to, the department said.

Meanwhile, many people stopped Friday at KVOA-TV in Tucson, an NBC affiliate, to sign a large outdoor banner with a photo of Nancy Guthrie and the message “Bring her home.”

“They're like family, you know,” said Sandy Bryant, referring to her yearslong enjoyment of the “Today” show and the Guthrie family's local ties. “It's painful. It's scary, very scary.”

Major U.S. crimes for years have been cracked with a tip. In 1995, the brother and sister-in-law of Ted Kaczynski recognized certain tones in an anonymous, widely published anti-technology manifesto. Known by the FBI as the “Unabomber,” Kaczynski was found living in a shack in Montana and subsequently admitted to committing 16 bombings over 17 years, killing three people.

The 1989 murders of an Ohio woman and two teen daughters in Florida were solved three years later when St. Petersburg police asked the public if they recognized handwriting found in the victims' car. A former neighbor led investigators to Oba Chandler.

Retired Detroit homicide investigator Ira Todd recalled how images from a gas station camera solved the disappearance and death of a 3-month-old baby — and stopped authorities from pursuing the wrong person in 2001. “A niece of this guy saw it on TV and says, ‘That’s my uncle,’” he said.

The murders of four University of Idaho students in 2022 generated nearly 40,000 tips to state and federal authorities. None had a direct role in the capture of Bryan Kohberger, but the public's involvement nonetheless was “absolutely” important, said Lt. Darren Gilbertson of the Idaho State Police.

“That's one of the things that kept us going for weeks,” he said, while authorities awaited DNA and other evidence.

Gilbertson said much of the early vetting in the Idaho murders was done by the FBI. He said agents and analysts who were screening tips had a good grasp of what information could be spiked and what should be handed up to key investigators. Some tips arrived by regular mail.

“Aliens to bears to crazy conspiratorial ideas — don't even pass that along,” Gilbertson said.

Nancy Guthrie was last seen Jan. 31 and was reported missing the following day. Hours before her family knew she was gone, a porch camera recorded video of a person with a backpack who was wearing a ski mask, long pants, jacket and gloves — images that were released by the FBI along with a public plea for help.

The FBI on Thursday said the person, now a suspect, is a man about 5 feet, 9 inches tall with a medium build. The agency also named the brand and model of the backpack.

Neighborhood resident Laura Gargano said she's tried to be helpful. She recommended that authorities look at an underground tank at Guthrie’s home, which was checked last weekend. She also told them that a rental house, not typical for the neighborhood, had recently been vacated.

“I noticed the cars were gone,” she told The Associated Press. “It could have been nothing, it could have been coincidental, but it was a change.”

The sheriff's department has not said whether any tips from the videos have advanced the investigation.

“I'm hopeful,” said Villaseñor, the former Tucson chief. “I have seen cases where simpler and less detailed information has helped bring somebody about. Maybe someone recognizes clothing, maybe the bag. You never know what someone will key on.”

PHOENIX (AP) — When Jennifer Rizzotti arrived at UConn as a player in 1992, the expectations around the school, as well as the women's basketball landscape, were much different than they are today.

Geno Auriemma was only in his eighth season coaching the Huskies. UConn hadn't yet hoisted a national championship trophy. There wasn't nearly the same pressure to win that the Huskies face now. And women's basketball as a whole hadn't seen the unprecedented growth in sponsorships and popularity it is experiencing now.

By the 1994-95 season, Rizzotti and fellow UConn standout Rebecca Lobo helped the Huskies go undefeated en route to their first national title. Everything about the program changed, and even as women's basketball has evolved and skyrocketed in exposure, the Huskies have remained the gold standard.

“There was no thought that we were going to be undefeated,” Rizzotti said. “We didn't have that internal pressure. We didn't have external pressure. That's the last time a UConn team could play that way. Think about that: 1995 is the last time a UConn team could play without that kind of pressure.”

The Huskies have since won 12 national titles, reached the Final Four 25 times and won 30 conference titles. They've been ranked 653 weeks in The Associated Press women's basketball poll, and Auriemma is the winningest coach in women's college basketball history.

As conversations around the Final Four in Phoenix center around how the women's game has grown, the Huskies, who are competing for the second straight national title, have been at the forefront.

“You could tell that everything was aligned for this program to reach that pinnacle," said Rizzotti, who is currently the president of the WNBA’s Connecticut Sun. “I don't think anything of us would have predicted that it would have gone on as it had.”

Rizzotti joined former UConn players Stefanie Dolson, currently with the WNBA's Washington Mystics, and Shea Ralph, now Vanderbilt's coach, on a panel Friday at “The AP Top 25 Fan Poll Experience,” which is being held at Arizona State’s First Amendment Forum in the Walter Cronkite School of Journalism and Mass Communication.

Earlier Friday, Big East commissioner Val Ackerman, former Metro Atlantic Athletic Conference (MAAC) commissioner Rich Ensor and AP women’s poll founder Mel Greenberg spoke on a panel moderated by college basketball analyst Debbie Antonelli on the growth of women's basketball at the college and pro levels.

“I think women's basketball has never been more popular,” said Ackerman, who was the first president of the WNBA from 1996-2005. “I think schools that are succeeding are really seeing, feeling and believing in the (return on investment). And UConn's a case in point.”

Ackerman sees the investment that the schools in this year's Final Four — UConn, Texas, South Carolina, and UCLA — have made in their programs to reach back-to-back national semifinals as a reflection of the growing importance of pouring resources into women's hoops.

“And that's done a world of good,” she added. “Programs like South Carolina, UCLA, you see what they're doing for their campuses. The investment is paying off in terms of the brand and engagement with the community and school reputation.”

Even as women's sports are drawing record crowds and WNBA players are set to make more money than ever, Ensor sees much more room to capitalize on this current growth.

“It has been about breaking down barriers, and they still exist,” Ensor said. “We marvel at what's happened, but we still recognize there's a lot more that's to come.”
