Investigators say a hair sample found in the home of 84-year-old Nancy Guthrie, who was abducted from her Tucson, Arizona residence on February 1, 2026, has not been linked to a suspect. The hair was tested but did not yield a DNA profile, according to the Pima County Sheriff's Office.
"The hair was done... and there was nothing," said Sheriff Chris Nanos about the sample, which was collected from Guthrie's home. The only known piece of biological evidence is a mixed DNA sample that includes as many as four individuals, the sheriff's office reported.
Nanos stated that multiple laboratories across the United States, including the FBI lab in Quantico, Virginia, and facilities in Kansas, Florida, California and Arizona, are working to analyze the DNA sample. "My understanding is there are at least five, maybe six, labs," the sheriff said.
Investigators believe Guthrie was taken by a masked man captured on her doorbell camera. Sheriff Nanos stated he is unable to determine if the masked man acted alone. "I don't think anybody's here ready to say it's one guy, it's 10 guys," Nanos said.
"Somebody in our community knows something. Call us, tell us, give us that information."
Nanos expressed confidence that the case is solvable and praised Savannah Guthrie, Nancy Guthrie's daughter, for keeping the case in the spotlight through Instagram posts. On February 12, 2026, a tent was placed over the front entrance of Guthrie's home to cover the area where her blood was found, the sheriff's office said.
