Hair found in Nancy Guthrie’s home not linked to suspect in abduction: Sheriff

(NEW YORK) — Testing on hair found at the home of “Today” show host Savannah Guthrie’s mother in the Tucson, Arizona, area is complete and does not point to a suspect in the 84-year-old’s abduction, Pima County Sheriff Chris Nanos told ABC News on Thursday.

“The hair was done … and there was nothing,” Nanos said in an interview. 

That leaves a mixed sample of DNA retrieved from Nancy Guthrie’s home as the only known piece of biological evidence, and one that has so far not been affirmatively linked to a suspect. 

The sample is a mix of as many as four people, the sheriff revealed. It’s not clear the technology even exists yet to untangle it, though the sheriff said multiple labs across the country are trying, including the FBI lab in Quantico, Virginia, and labs in Kansas, Florida, California and Arizona.

“My understanding is there are at least five, maybe six, labs across the country that are working on all of this,” Nanos said. “We have some of the brightest minds in the nation, if not the world, working on this.”

Investigators believe Guthrie was taken from her home in the early hours of Feb. 1 by a masked man captured on her doorbell camera. But six months later, Nanos is unable to say whether that masked man was working alone.  

“I don’t think anybody’s here ready to say it’s one guy, it’s 10 guys,” Nanos said.  “Did he have help? Could have.”

Danish high schoolers will have to verbally defend written assignments, in government move to combat AI cheating

(CNN) — High school students in Denmark will be required to verbally defend their written assignments as part of emergency government measures aimed at combating AI cheating.A verbal defense will be needed for all exams written at home, Denmark’s Ministry of Education announced in a statement Thursday, adding that it will work with schools to create the best framework for this.The rule, which comes into force immediately, applies to students in upper secondary education, which typically begins around age 16. It will include the approximately 9,000 students enrolled in the country’s two-year Higher Preparatory Examination program, who have to submit major written assignments each year, according to the ministry.The ministry is also calling on high schools to use tools to monitor students’ screens during exams, as well as a firewall to filter the content they can access during exams and in class.In addition, it is encouraging schools to get students to complete more assignments in school, under controlled environments, to make supervision easier.“Unfortunately, we have a problem with students using AI to cheat in upper secondary school,” Education Minister Magnus Heunicke said in the statement. “Action is needed now, and we are starting with these three initiatives.”“In the coming period, I will be engaging with schools, teachers and students about what can be done both in the short and longer term to ensure that AI does not undermine students’ skills, academic abilities and, not least, their ability to think for themselves,” he continued.‘Important first step’Three upper secondary school organisations — representing school leaders, teachers and students — welcomed the moves but called for more long-term solutions due to the “rapid pace of technological development,” the high schools association, Danske Gymnasier, said in a statement Thursday.Anders Frikke, chair of the Danish Association of Upper Secondary School Teachers (GL), said teachers “appreciate” that the education minister “has acted both swiftly and decisively. However, we also have additional proposals that we hope the Minister will consider.”“These include requiring students to clearly declare when AI has been used in major written assignments and ensuring that preparation for oral examinations takes place without access to AI,” he added.While students also “welcome” the emergency initiatives, “it is important that the increased amount of written work carried out at school is organised in a way that genuinely strengthens students’ learning, rather than simply moving the work from home to school,” Oscar Tønsberg Hoffmann, chair of the Danish Upper Secondary Students’ Association (DGS), said in the statement.He added that it is “essential that students have the opportunity to contribute to the development of longer-term solutions.”The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
