FBI video forensics experts have been seen at the home of Nancy Guthrie in Tucson, Arizona, as the search for the missing 84-year-old woman continues for its 12th day. The specialized team was observed bringing in equipment to the area where blood was previously found, indicating the seriousness of the investigation. The unit is known for its previous involvement in high-profile cases, including assisting with the investigation into Bryan Kohberger, who was sentenced to life in prison for the murder of an Idaho student.

The presence of the FBI's Video Forensic Analysis Unit suggests that investigators are taking a thorough approach to the case, and they might be employing advanced forensic techniques that include comparison of physical conditions at the scene with any available surveillance footage. While the use of such forensic methods underscores the urgency of locating Guthrie, it also highlights the complexity of cases involving missing persons, especially when initial leads do not provide clear answers.

As the investigation progresses, the involvement of the FBI raises questions about the possible leads or evidence they may have uncovered. Furthermore, the urgency expressed by local authorities to locate Guthrie as quickly as possible illustrates the community's concerns and the empathy shown towards her family during this distressing time. This case continues to draw attention as it underscores broader issues related to elder safety and the prevalence of missing persons in the U.S.
