Overnight activity at Nancy Guthrie's house as search continues

Authorities intensified the search for missing Nancy Guthrie as the investigation entered its 13th day, with police conducting overnight operations at her Tucson home while issuing another public plea for information about her whereabouts. The continued search comes as concerns grow for Guthrie's safety, with law enforcement officials maintaining a visible presence around her residence overnight. Tucson Police Department has been leading the investigation, coordinating efforts with other local agencies as they follow up on leads and interview potential witnesses. The overnight activity suggests that investigators may be following new information or conducting forensic examinations of the property. Nancy Guthrie, a resident of Tucson, was reported missing approximately two weeks ago, and her family has been cooperating fully with authorities, expressing both hope and anxiety as the days pass without concrete information about her location.
