What happened overnight — Latest on the Nancy Guthrie
A coordinated late-night operation by the FBI and Pima County SWAT near Tucson, Arizona resulted in multiple detentions and a vehicle seizure about two miles from Nancy Guthrie’s residence.
Authorities said they executed a search warrant at a nearby home and towed a Range Rover from a Culver’s parking lot while forensic teams processed evidence at the scene.
Evidence and forensic updates investigators confirmed
DNA testing on blood found on Guthrie’s front porch has come back as matching her, officials reported in recent briefings.
Surveillance footage reviewed by investigators shows a masked, armed person tampering with the home’s doorbell camera on the night Guthrie disappeared — that video remains a key lead.
Who is involved in the probe right now
The FBI is leading a joint investigation with the Pima County Sheriff’s Department and local law enforcement; both agencies say the search is active but declined to provide further operational details.
Media outlets reported at least three people were detained during the operation; authorities emphasized that detentions are part of routine scene control and do not equal arrests or charges.
What authorities are asking the public to do
Officials continue to request any neighborhood video, doorbell footage or dashcam clips from late Jan. 31–Feb. 1 be submitted to investigators.
If you have information, contact the FBI tip line or the Pima County Sheriff’s Office; law enforcement says tips have been crucial and a reward has been increased to encourage more leads.
