The FBI has released a description of the suspect in the disappearance of Nancy Guthrie, an 84-year-old woman who vanished from her home in Tucson, Arizona on February 1st. The suspect is described as a male, approximately 5'9" to 5'10" tall with an average build. In a surveillance video released by the FBI, the suspect is seen wearing a black, 25-liter 'Ozark Trail Hiker Pack' backpack. The FBI is offering a reward for information leading to the suspect's capture. The investigation has led authorities to request that Guthrie's neighbors review their security camera footage for any suspicious activity. Meanwhile, the Pima County Sheriff's Department is working with the FBI and has not found a glove at Guthrie's home. The sheriff has also addressed criticism of his department's handling of the crime scene, stating that deputies had already collected the evidence they needed. The search for Guthrie continues, and the FBI is seeking any video showing vehicles, traffic, pedestrians, or suspicious activity from January 1st to February 2nd. The case has sparked speculation about the involvement of cartels or another nation state, but President Trump has stated that it's 'a little bit early' to make such conclusions. The FBI's decision to increase the reward for information on Guthrie's whereabouts is seen as a strategic move to target someone close to the perpetrator. Forensic expert Joseph Scott Morgan suggests that the suspect may have cased Guthrie's property beforehand, and a law enforcement expert speculates that investigators are reviewing sales of Ozark Trail backpacks at Walmart stores in the Tucson area. The disappearance has also drawn attention to a crime surge in the region, with large encampments containing drug and criminal activity located near Guthrie's home. The FBI will continue its investigation regardless of weather conditions, and the case has led to the repeated questioning of neighbors about truck ownership, raising questions about the role of a gray truck spotted on surveillance footage.
