Federal Bureau of Investigation (FBI) analysts have begun advanced DNA testing on a hair sample from the Tucson, Arizona, home of Nancy Guthrie, the 84-year-old mother of Today Show anchor Savannah Guthrie, but the mixed genetic profile could take six more months to untangle.
The sample reached the FBI Laboratory only in recent weeks, 11 weeks after a private Florida laboratory working with the Pima County Sheriff's Department collected it in February. An FBI official said the bureau had requested the material more than two months ago, describing the delayed handover as part of a continuing forensic process rather than a breakthrough.
