The provided articles do not directly mention KVOA. Instead, they focus on the disappearance of Nancy Guthrie, the mother of NBC's "Today" show host Savannah Guthrie, in the Tucson, Arizona area. The Pima County Sheriff's Department, led by Sheriff Chris Nanos, is heading the investigation, with the FBI also involved. The case is newsworthy due to the high-profile nature of Savannah Guthrie and the ongoing search efforts. Recent developments include the release of door camera video and still images of a masked suspect by the FBI, leading to over 18,000 tips. There have also been accusations that the Pima County Sheriff withheld forensic evidence from the FBI, which the sheriff denies. The search of the desert terrain near Nancy Guthrie's home has yielded little progress. The case remains significant due to the intense public interest and the ongoing efforts to locate the missing 84-year-old.
