Overview
- Federal agents conducted renewed activity at the Catalina Foothills property on Feb. 25 in preparation for handing it back to the Guthrie family, while emphasizing the case remains active.
- More than 23,000 tips have reached the FBI since the disappearance, including some 750 in the first 12 hours after the family announced a private reward of up to $1 million; the FBI’s separate $100,000 reward remains in place.
- Forensic work has not produced usable matches, with sources describing some DNA from inside the home as low‑level or mixed, a glove DNA profile yielding no CODIS hit, and lab enhancement and investigative genetic genealogy ongoing.
- Authorities have not identified a suspect and say Nancy Guthrie’s three adult children and their spouses have been cleared as possible suspects.
- Doorbell images previously released by the FBI show a masked person tampering with the camera, while officials note the timing of one image without a backpack is unresolved due to the lack of a timestamp.
