The development comes as authorities say the investigation remains active and thatDNA analysismay soon identify whose blood was found on Nancy's property. Pima County Sheriff Chris Nanos has said forensic teams are moving closer to a result, while NBC News reported that investigators have gathered thousands of hours of video and continue to examine digital evidence tied to the disappearance.

According toRob Shuter's Naughty But Nice Substack, Savannah has assembled a team of private detectives, former federal agents and security specialists to follow leads connected to her mother's disappearance. The report said she has refused to scale back the operation despite the cost, with people close to the situation claiming she still believes Nancy can be found.

The same report also suggested Savannah has grown frustrated with the pace of the official investigation. One source quoted by Shuter claimed she was unwilling to rely solely on law enforcement and was prepared to continue funding additional investigative work if it could help uncover new information.

That frustration comes against a wider backdrop ofscrutiny surrounding the investigation. Reuters previously reported that the FBI was unable to access some evidence after the sheriff's office sent items to a private laboratory in Florida instead of the bureau's own crime lab. The decision drew criticism and prompted questions about whether the handling of forensic evidence had slowed parts of the investigation.

The case has also attracted sustained national attention because of Savannah Guthrie's profile as a television host. Since Nancy disappeared in February, investigators have faced a heavy flow of public tips, online speculation and media scrutiny while continuing to reconstruct the events surrounding her disappearance.

Nancy's disappearance remains unsolved after she vanished on February 1 from her Tucson home. Investigators have treated the case as a possible abduction after signs of violence, ransom notes and reports of a masked figure near the property surfaced early in the investigation.
