Nancy Guthrie scene hair sample DNA test yields no profile, sheriff says

Key Points:

• Investigators in the Nancy Guthrie disappearance case were unable to obtain a DNA profile from a hair sample found in her home, according to Pima County Sheriff Chris Nanos. The sample was tested in a California lab but yielded no DNA results.
• The hair sample has been preserved for potential future use, as its value may be determined once a suspect is identified and comparison can be made.
• DNA testing remains a key focus in the investigation, with multiple crime labs involved and the use of investigative genetic genealogy to generate leads.
• Guthrie, 84 and mother of "Today" co-host Savannah Guthrie, has been missing for nearly six months, and authorities continue to seek tips, offering over $1.2 million in combined rewards for information leading to an arrest.
• A suspect was captured on a doorbell camera wearing a mask, gloves, long sleeves, and carrying a black Ozark Trail backpack; the FBI and family urge anyone with information to contact law enforcement immediately.
