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. The FBI also released a surveillance video showing the suspect wearing a black, 25-liter 'Ozark Trail Hiker Pack' backpack. The search for Guthrie, who is the mother of NBC host Savannah Guthrie, continues its 13th day. The FBI has increased the reward for information on Guthrie's whereabouts, and is working closely with the Pima County Sheriff's Department. The sheriff's department has not found a glove at Guthrie's home, and has sent evidence to a private lab in Florida. The disappearance has drawn attention to a crime surge in the region, with large encampments containing drug and criminal activity located nearby. Federal authorities are asking for any video showing vehicles, traffic, pedestrians, or suspicious activity from January 1st to February 2nd. The case has also sparked speculation about the involvement of cartels or another nation state, but President Trump has stated that it is 'a little bit early' to make such conclusions.
