The search for 84-year-old Nancy Guthrie entered its twelfth day, marked by a significant escalation in investigative resources. FBI video forensics experts arrived at Guthrie’s Tucson home, a location already known to investigators due to the discovery of blood evidence.
Members of the FBI’s Video Forensic Analysis Unit were observed carrying multiple hard cases into a tent erected at the front door. This specialized team previously played a crucial role in the Idaho student murder case, assisting in the capture of Bryan Kohberger, now serving a life sentence.
Investigators also brought in a forensic height board, a tool used to meticulously compare physical dimensions at the scene with figures captured in surveillance footage. This suggests a focused effort to analyze the movements and stature of anyone present at Guthrie’s home during the critical timeframe.
The FBI’s Forensic Audio, Video and Image Analysis Unit is renowned for its ability to enhance and clarify surveillance video, authenticate recordings, and detect tampering. Their expertise extends to restoring damaged media and providing compelling expert testimony in court.
Beyond routine enhancement, the team’s capabilities include extracting still images for comparison, interpreting timestamps, and converting various video and audio formats into standardized digital files for in-depth review. This meticulous process is vital for uncovering hidden details.
A box for a Blackmagic Design UltraStudio 4K Mini, a professional-grade device used in broadcast production, was also brought into the home. This tool allows for the capture and conversion of high-resolution video and audio, crucial for preserving and analyzing evidence.
According to retired FBI Supervisory Special Agent Jason Pack, the team may be taking precise measurements of the home’s architecture – archways, bricks, and stones – to calculate the height of a masked individual seen on Guthrie’s doorbell camera footage. These details could prove pivotal.
The timeline of Guthrie’s disappearance is starkly defined. On January 31st, family dropped her off at home around 9:30 PM, and the garage door closed shortly after. The following day, at 1:47 AM, the doorbell camera abruptly disconnected.
Further unsettling events unfolded: motion was detected by a security camera at 2:12 AM, and Guthrie’s pacemaker disconnected from its monitoring application at 2:28 AM. The family discovered her missing the next morning when she didn’t attend her weekly church livestream.
A 911 call was placed at 12:03 PM on February 1st, and sheriff’s deputies arrived at the home just twelve minutes later. The investigation remains active, and the FBI is offering a $50,000 reward for information leading to Nancy Guthrie’s safe return.
