KVOA

The provided articles do not mention KVOA. They center on the disappearance of Nancy Guthrie, the mother of NBC's Today show host Savannah Guthrie, in the Tucson, Arizona area. The 84-year-old is believed to have been abducted. The Pima County Sheriff's Department, led by Sheriff Chris Nanos, is heading the investigation, with the FBI also involved. The sheriff has denied accusations of withholding forensic evidence from the FBI. The investigation has generated significant public interest, with over 18,000 calls received with tips. Despite extensive searches of the desert terrain near Guthrie's home and the release of video and images of a masked suspect, the search has so far yielded few results. The case remains highly relevant due to the ongoing search and the involvement of a prominent media figure's family.
