Sheriff says hair evidence in Savannah Guthrie mother's abduction yields no suspect link

Pima County Sheriff Chris Nanos told ABC News that forensic analysis of hair recovered from the Tucson home of Savannah Guthrie's mother, Nancy Guthrie, did not match any suspect in the 84-year-old woman's abduction. > "The hair was done ... and there was nothing," Nanos said. The only remaining biological evidence is a mixed DNA sample that could contain material from up to four individuals. Nanos said the technology to separate the contributors has not yet been proven, but at least five or six laboratories nationwide, including the FBI lab in Quantico and facilities in Kansas, Florida, California and Arizona, are working on the case. Investigators suspect the victim was taken from her residence in the early hours of Feb. 1 after a masked man was captured on a doorbell camera, though the sheriff could not confirm whether the perpetrator acted alone. > "I don't think anybody's here ready to say it's one guy, it's 10 guys. Did he have help? Could have," Nanos said. Nanos expressed confidence the case can be solved and praised Savannah Guthrie for keeping public attention on the investigation through her social-media posts. He urged anyone with information to contact authorities, saying someone in the community likely knows the victim's whereabouts.
