Arizona Law Enforcement

Arizona authorities say cadaver dogs previously used in the search for 84‑year‑old Nancy Guthrie, the missing mother of NBC "Today" co‑host Savannah Guthrie, are no longer being actively deployed as the suspected abduction investigation enters its fifth week in Tucson’s Catalina Foothills. Pima County Sheriff Chris Nanos confirmed the dogs were used earlier in the case and remain "available if needed" but declined to discuss specific leads, while a National Police Association spokeswoman, speaking generally, outlined reasons departments may stand down cadaver K‑9s, including credible belief a victim may still be alive or lack of a clear search area. Investigators believe Nancy Guthrie was kidnapped from her home around 2:30 a.m. on Feb. 1, and the main public lead remains Nest camera footage of a masked intruder of medium build, about 5'9" to 5'10" tall, carrying a black Ozark Trail backpack. The sheriff’s office previously drew on Border Patrol K‑9 resources and continues to maintain a presence at the home as family visits and public interest remain intense, illustrating how investigators sometimes narrow or shift search tactics even in high‑profile missing‑person cases.
