FBI video forensics experts have been spotted arriving at the Tucson residence of Nancy Guthrie, an 84-year-old woman who has been missing for 12 days. Their presence marks a significant development in the ongoing investigation, particularly after the discovery of blood at her home.
Exclusive images provided to Fox News Digital depict the FBI’s Video Forensic Analysis Unit team as they transport several Pelican-style hard cases into a tent set up at the front door of Guthrie’s house. This specialized equipment is expected to play a crucial role in the investigation.
Notably, this same unit was instrumental in the capture of Bryan Kohberger, the individual responsible for the murder of Idaho students and who is currently serving a life sentence.
The investigators also brought along a forensic height board, a tool used to compare physical dimensions at the site with footage captured by surveillance cameras, offering potentially valuable insights into the case.

The FBI does not publicly release a case-by-case list of investigations handled by its forensic video specialists. But the bureau’s Forensic Audio, Video and Image Analysis Unit, part of the FBI Laboratory and Operational Technology Division, routinely provides technical support in some of the nation’s most high-profile cases.
According to FBI materials, the unit is responsible for enhancing and clarifying surveillance video, authenticating recordings and analyzing possible edits or tampering, extracting still images for investigative comparison, interpreting timestamps and metadata, restoring damaged or obsolete audio and video media and providing expert testimony in court.

In the University of Idaho quadruple homicide case, the FBI assisted local authorities with digital evidence review and surveillance analysis used to track the suspect’s vehicle across multiple locations. Historically, FBI digital evidence teams have supported cases ranging from the 9/11 attacks to the Enron fraud prosecution. And the bureau has said its digital evidence laboratory conducts hundreds of audio and video examinations each year.
Fox News Digital also observed a box for a Blackmagic Design UltraStudio 4K Mini being brought into the home. It’s a device used in professional broadcast production.

Tech expert Kurt “CyberGuy” Knutsson told Fox News Digital the UltraStudio 4K Mini is designed to capture and convert high-resolution video and audio across multiple formats.
“It’s a professional-grade tool often used in broadcast environments,” Knutsson said. “It allows you to ingest video from various sources and convert it into high-quality digital formats for analysis or sharing.”
Knutsson said the device could potentially be used to transfer video or audio from various formats into standardized digital files for preservation or further forensic review.

“It’s possible they’re taking precise measurements of the archway, the bricks, the stones and other fixed structures,” said retired FBI Supervisory Special Agent Jason Pack.
The measurements can help calculate the height of the masked man seen on Guthrie’s doorbell camera footage.Â
The FBI is offering a $50,000 reward for information leading to Guthrie’s whereabouts. The investigation remains active and ongoing.
