Timeline Highlights

Feb 1, 2026

Nancy arrives at Annie's for dinner

January 31, 5:32 p.m. MST — Nancy takes an Uber to daughter Annie's home for dinner and game night.

Feb 1, 2026

Nancy dropped off at home — last sighting

January 31, 9:48 p.m. MST — Annie's husband, Tommaso Cioni, drives Nancy home from dinner and game night. Cioni ensured Nancy made it safely inside the house before leaving. Garage door closed at approximately 9:50 p.m. This is the last confirmed sighting of Nancy Guthrie. Sheriff Nanos told The New York Times that Cioni watched her go inside.

Feb 1, 2026

Doorbell camera disconnected

February 1, 1:47 a.m. MST — Nancy's Google Nest doorbell camera goes offline. FBI later confirmed the camera was physically removed from the home. Recovered footage captured before disconnection shows a masked, armed individual approaching the front door, attempting to cover the camera with a gloved hand, and then ripping out a plant from the yard to place in front of the camera to block the view. Despite physical removal, the FBI's forensic team successfully recovered data from the device.

Feb 1, 2026

Motion detected at residence

February 1, 2:12 a.m. MST — A secondary camera system's software detects a person at the residence. No video was recorded because Nancy did not have an active subscription to the surveillance service. This is approximately 25 minutes after the doorbell camera was disconnected and 16 minutes before the pacemaker lost connection — placing it within the critical 40-minute window (1:47 a.m. to 2:28 a.m.) that investigators have zeroed in on as the likely abduction period.

Feb 1, 2026

Pacemaker disconnects from phone app

February 1, 2:28 a.m. MST — Nancy's pacemaker device loses its Bluetooth connection to the monitoring app on her phone. Her phone was later found inside the home. This suggests she was removed from proximity to the phone, or the pacemaker was disrupted.

Feb 1, 2026

Family discovers Nancy missing

February 1, approximately 11:56 a.m. MST — Nancy had a standing Sunday routine with a small group of close friends to gather at one another's homes and watch a New York-based church service via livestream. When she did not arrive that morning, one of the friends contacted her daughter Annie to report that Nancy had not shown up and could not be reached. Annie and family went to Nancy's home and discovered she was missing. 911 call placed at approximately 12:03 p.m. The home showed signs of forced entry, the doorbell camera had been physically removed, Nancy's cell phone was left inside, and blood was later found on the front porch.

Feb 2, 2026

Authorities confirm abduction

February 2 — Press conference by Pima County Sheriff Chris Nanos and FBI. Authorities state Nancy was 'taken in the middle of the night' and classify the case as an abduction based on evidence at the scene.

Community vigil at St. Philip's in the Hills — 400+ attendees

February 4, 2026 — A community vigil for Nancy Guthrie was held at St. Philip's in the Hills Episcopal Church in Tucson. Approximately 400-500 people attended. The service was also livestreamed. Family members participated in the vigil, which drew significant media attention and community support.

Feb 4, 2026

FBI searches Annie and Tommaso's home — twice

February 4 and February 7, 2026 — The FBI searched the home of Annie Guthrie and Tommaso Cioni on two separate occasions. The searches were part of standard investigative procedure. FBI also canvassed Annie's neighborhood. This is notable because Tommaso was the last person to see Nancy alive, and journalist Ashleigh Banfield's source controversially described him as a 'possible prime suspect' — a characterization that Sheriff Nanos publicly denied, calling Banfield's reporting 'irresponsible and reckless.'

Feb 5, 2026

FBI announces $50,000 reward

February 5 — FBI announces $50,000 reward for information leading to Nancy's recovery or the arrest of the person responsible. Blood on front porch confirmed as Nancy's via DNA testing. First ransom deadline ($4 million) passes with no payment made; the ransom Bitcoin wallet remains empty. FBI arrests California man Derrick Callella for sending fraudulent Bitcoin ransom texts to the Guthrie family. Callella used a virtual phone number registered to an email containing his name, accessed from an IP address at his California residence. He told authorities he 'was trying to see if the family would respond.' Charged with intent to transmit a demand for ransom and making harassing phone calls without disclosing identity. His texts have NOT been linked to the original ransom note.
