Overview
- Nancy Guthrie, 84, was last seen at her Tucson home on Jan. 31 and reported missing the next day, and investigators say they believe she was taken against her will.
- No arrests have been made and Pima County Sheriff Chris Nanos has publicly cleared immediate family members as possible suspects.
- Investigators have recovered unidentified DNA and officials say state and federal labs are working to make that DNA usable, including reported use of investigative genetic genealogy to search for relatives of the source.
- Authorities have collected and are reviewing thousands of surveillance videos and digital records, and an earlier masked figure flagged in the probe was later ruled unrelated.
- John Bennett Ramsey urged the Guthrie family to press investigators about DNA and resources, a high‑profile intervention that has increased public scrutiny and could push for more outside expertise or forensic steps in the coming weeks.
